[meteorite-list] CHELYABINSK

[DAN via Meteorite-list]

It was 8 years ago that arguably this most well documented fall occurred over 
Chelyabinsk, Russia.This 254 g specimen is a size not commonly offered, is 90% 
fusion crusted, and bears a few shallow regmaglyphs on one end.Asking  
$9/gram.Images available. 
Have an impactful day, DAN

[meteorite-list] Chelyabinsk-like meteorites may strike Earth twice this century

[Shawn Alan via Meteorite-list]

Hello Listers,

Chelyabinsk-like meteorites may strike Earth twice this century

Source: REX

The threat of an asteroid or meteorite attack on Earth is still
relevant, Professor of the Ural Federal University, Victor Grokhovsky
believes. 

According to the scientist, large celestial bodies "attack" planet Earth
approximately three times in 100 years. Therefore, we may witness
another meteorite attack, similar to the one that occurred in the sky
above Chelyabinsk, Russia. 

"In this century, the first large meteorite exploded in the sky over
Chelyabinsk. It is quite possible that objects similar to the
Chelyabinsk meteorite may strike Earth once or twice this century," the
professor told TASS, Pravda.Ru says. 

Grokhovsky explained that his theory was based on the statistical data
of meteorite attacks on Earth in the last hundreds of years.

According to Grokhovski, scientists do not know much about the threats
that planet Earth may encounter in space.

Pravda.Ru

http://english.pravda.ru/news/science/14-10-2015/132322-chelyabinsk_meteorite-0/

I would say this is true, hello is a stony meteorite and we get hit by
those a lot. What would be cool is if it was a lunar meteorite :))

Thank you Jason, Francesco,

I wasn't sure of when the KE was released and/or what it was capable of.

All best, John

When meteorites fragment, they don't "explode."  Think about the forces at 
work; ram pressure and internal strain being released. 
Theoretically, nothing should be imparted with any "upward" KE.  In reality, 
some fragments do move vertically upward relative to 
the bolide's center of mass, but there are no substantive forces at play that 
would cause fragments to move against gravity --  
unless you have a rare event like the '1972 Great Daylight Fireball,' when the 
object's original trajectory took it skimming across 
the atmosphere and back into space.

If bolides did "explode" with appreciable force, try to envision what the 
structure of a strewnfield would be: instead of larger 
masses being concentrated at one end of a strewnfield, they *should* be found 
all around the periphery of the field -- perhaps 
~concentrated at one side due to initial KE, but there would be exceptions.  We 
don't observe that..


Regards,
Jason

Re: [meteorite-list] Chelyabinsk as a model for Tunguska

[E.P. Grondine via Meteorite-list]

Hi all - 

Perhaps modeling the fall of the fragments remaining after the airburst at 
Chelyabinsk 
may provide some estimate as to the location of the landing site of any 
fragments left after
the Tunguska airburst.

Even if most of the Tunguska impactor turned to fine dust, 
perhaps some lof it survived intact with momentum. 

Of course, after more than 100 years on the ground,
it is highly unlikely that any piece survives survives intact,
but even a soil stain could clear up a lot of mysteries.

good hunting,
Ed

Re: [meteorite-list] Chelyabinsk TKW

[cbo via Meteorite-list]

Dear Bernd!

I thought for the found and collected pieces not for the original object.

So many meteorite has found by the Russian officials, hunters and orhers.

The TKW in the MetBull 1 t. But I think the real TKW its over 1 t by hunters 
and orhers.
We can just estimatate the correct mass.

"Do you know (or estimate) anybody that what

Hello Zsolt and List,

Not quite sure what you mean but Brown estimates the *original object*
had a diameter of about 54 feet (17 m) and a mass of roughly 10,000
metric tons.

According to the writeup from MB 101:

The total mass collected by local people is certainly > 100 kg and perhaps > 
500 kg.

Re: [meteorite-list] Chelyabinsk Meteorite Sheds Light on Dinosaur Extinction Mystery

[Galactic Stone & Ironworks via Meteorite-list]

Hi Vishnu and Larry,

This is why I love the Meteorite List so much.  Ask a layman question,
and get scientists who will gladly answer that question.  :)

Thanks to both of you for taking the time to answer my query and
improve my understanding.

So, we still do not know the composition of the KT impactor.  Does
anyone else find it surprising that there are no extant remnants of
this impactor?  Or, is the fossil meteorite found by Frank Kyte
considered to be such a remnant?  Granted, the impact happened a very
long time ago, but would not an impact of that scale leave behind
something that would still remain today?

Best regards,

MikeG

Hi Mike

The original link between Baptistina Family and the K/T impactor was proposed 
based on the composition of the "fossil" meteorite that was discovered in the 
K/T layer by Frank Kyte at UCLA. 
Here is a quote from his 1998 paper. 

"The fossil meteorite from DSDP Hole 576 appears to be from (1) a chondritic 
meteorite with (2) significant amounts of metal and sulphide (4-8%), (3) large 
inclusions [larger than 200 um] of mafic minerals that also contained metal, 
and (4) 30-60% fine-grained matrix. The known meteorite groups that best fit 
these criteria could be the CV, CO, and CR carbonaceous chondrites."

Bottke et al. proposed the link between K/T impactor and Baptistina family 
based on dynamical evidence and also the colors (very rudimentary analog for 
composition). Baptistina asteroid family seems to have lower albedo and weaker 
absorption bands similar to what one would expect for a carbonaceous asteroid. 

We looked at several members of Baptistina asteroid family and got their 
near-IR spectra to constrain their surface composition.  What we noted was that 
Baptistina family asteroid spectra looked very similar to the background Flora 
family but were subdued by some unknown darkening material. The mineralogy of 
Baptistina suggested that they were similar to LL chondrites just like the 
Floras. We also looked for OH/H2O absorption bands in Baptistina asteroid 
family and found none. Our rationale there was if some of them were mixtures of 
LL chondrite material and carbonaceous then they could show such a feature. We 
see these OH/H2O bands in some of the carbonaceous meteorites under the right 
laboratory conditions on Earth. We found no such evidence and so ruled out the 
possibility of the darkening agent being a carbonaceous impactor like we see on 
Vesta. There is no evidence from LL chondrites for widespread carbonaceous 
xenoliths like we see in howardites. So there is also not much suppo
 rt from the meteoritical side. Shock darkening and impact melt that we see on 
Chelyabinsk seems to be the most logical way to explain the spectral properties 
observed on Baptistina family. 

The take away message would be that if BAF is the source of the K/T impactor 
then K/T impactor is not carbonaceous contrary to what Kyte reports. A more 
logical conclusion would be that Baptistina Asteroid Family had nothing to do 
with the K/T impactor in the first place and the compositional link between the 
K/T impactor and BAF asteroids is not valid in light of what we see in 
Chelyabinsk. So the original hypothesis that K/T impactor might be carbonaceous 
remains. 

I hope that clears the air.

Vishnu Reddy

Re: [meteorite-list] Chelyabinsk Meteorite Sheds Light on Dinosaur Extinction Mystery

[Larry Lebofsky via Meteorite-list]

Hi Mike:

That is not what the press release says.

It is still thought that the KT impactor was carbonaceous. There was also
thought, based on being dark and formation age of the BAF (when the parent
body was disrupted), that the BAF was the source of the KT impactor.
However, there is a better spectral match between the Baptistina Asteroid
Family members and the shocked-darkened material seen in the Chelyabinsk
meteorites than there is between these members and carbonaceous
meteorites. This implies that the BAF members are shock-darkened and not
carbonaceous.

Re: [meteorite-list] Chelyabinsk Meteorite Sheds Light on Dinosaur Extinction Mystery

[Galactic Stone & Ironworks via Meteorite-list]

This is an interesting theory.  But, how does Chelyabinsk completely
rule out a carbonaceous KT impactor?  Until we recover an extant
sample of the KT impactor, the question is still unanswered.  Yes,
there are dark meteorites that are not carbon-rich.  But how does this
fact rule out a carbonaceous (or any) impactor for the KT impact?  Am
I missing something?

Best regards,

[meteorite-list] Chelyabinsk Meteorite Sheds Light on Dinosaur Extinction Mystery

Russian Meteorite Sheds Light on Dinosaur Extinction Mystery

July 16, 2014, Tucson, Ariz. -- A long-standing debate about the source of
the asteroid that impacted the Earth and caused the extinction of the
dinosaurs has been put to rest thanks to the Chelyabinsk meteorite that
disintegrated over Russia in February 2013, a new paper published in the
journal Icarus shows.

Astronomers have debated whether the dinosaur killer was linked to the
breakup of a large asteroid forming the Baptistina Asteroid Family (BAF)
beyond Mars, some of which ended up on Earth-crossing orbits. The asteroid
impacting Earth is thought to have been dark and carbonaceous. The BAF
hypothesis was bolstered by them being dark and with a spectral shape
similar to carbonaceous meteorites.

Analysis of the Chelyabinsk meteorite shows that shock produced during
catastrophic disruption of a large asteroid can darken otherwise bright
silicate material. Shock darkening was first reported by Dan Britt (now at
the University of Central Florida) in the early 1990s. The Chelyabinsk
meteorite has both bright unshocked and dark shocked material. However, the
details of the spectra of the dark Chelyabinsk material closely reproduces
spectral signatures seen with members of the Baptistina Asteroid Family,
said Planetary Science Institute Research Scientist Vishnu Reddy, lead
author of  "Chelyabinsk meteorite explains unusual spectral properties of
Baptistina Asteroid Family that appears in Icarus.

"Shock and impact melt can make bright asteroids dark, Reddy said. "In
other words, not all dark asteroids are rich in carbon as once thought."
The latest measurements rule out the possibility for the Baptistina family
being the source of the K/T impactor, he added.

'The link between the K/T impacator, thought to be carbonaceous, and BAF,
has been proved invalid," Reddy said.

Chelyabinsk provided a great opportunity to see the mixture of shocked and
unshocked material in a single meteorite, Reddy said while cautioning that
no clear evidence exists that the Russian meteorite itself came from the
Baptistina family.

"The new finding has implications for hazards from Near-Earth Objects and
for mining asteroids for space-based resources," Reddy said. "A potential
target identified as primitive and rich in volatiles/organics and carbon
based on its spectral colors could in fact be just shocked material with
entirely different composition."

PSI researchers David P. O'Brien and Lucille Le Corre were among the
co-authors on the paper.

This research work was supported by grants from NASA's Planetary Mission
Data Analysis Program, NEOO Program and Planetary Geology and Geophysics
Program.

Guys,
Check this version out that appeared earlier on youtube. You can see
the blast of snow and ice downwind from the fall.

Re: [meteorite-list] Chelyabinsk Meteorite Falling in Dark Flight

[karmaka]

Dear list members,

the moving dark spot in the footage does definitely not show the falling 
meteorite because the direction does not
fit to the location of the impact hole in the ice of the lake. It's probably a 
bird.

Graham, I've analysed the footage and could not see the mass fall.

the main mass of Chelyabinsk hitting the lakethe spash/ impact can

[meteorite-list] Chelyabinsk Meteorite Falling in Dark Flight

[J Sinclair]

Hi List,

On March 24, Martin Goff posted on FB a link to a video that shows
some different footage of the Chelyabinsk event. It's entirely in
Russian and over 12 minutes long but it's worth a look.

I noticed at minute 10:30 of the video there is a clip of a
meteor(ite) falling in dark flight.
It's only about 3 seconds of video but there appears to be a black
rock tumbling straight down from the sky.

https://www.youtube.com/watch?v=YgZuqm7893A

Chelyabinsk continues to amaze.

John

Congratulations to Dr Svend Buhl and his team on the Chelyabinsk Strewn Field 
map.

A historical record of the meteorite of the century has been created for future

http://www.meteorite-recon.com/img_inventar/Chelyabinsk_strewnfield_map_7500.jpg

For background information see:

http://www.meteorite-recon.com/en/Meteorite_Chelyabinsk_6.html

In March our calculations gave a window of 200 – 800 kg for the Lake Chebarkul
fragment. Our scenario and the resulting map used a conservative value of 300 kg
for this mass. Now, after its successful recovery, the determination of its
approximate mass (~ 600 kg) enabled us to narrow a few parameters of the
trajectory and dark flight. The resulting minor changes in the final map are
listed below:

- The transverse displacement of the calculated wind shift discounted
impact point for the lake mass is reduced from 1.100 m to 950 m.
- As a result, the trajectory is slightly displaced to the south, albeit
with the map scale used, the change is of no consequence for the depiction
- Impact velocity for the lake mass is ~ 550 km/h instead of ~ 500 km/h
- The altitude at which the transition into dark flight occurred is ~ 14
km instead of 14.7 km

In addition to these changes, within the last two months a total of 34 masses
with documented find locations were submitted and successively added to the map.
These recently discovered masses range from 0.5 g to 1,440 g. The final version
of the strewnfield map now shows 285 find locations of Chelyabinsk meteorites,
of which 228 were submitted with their respective weights.

Karl and I would like to thank all contributors.

Cheers

Svend

[meteorite-list] Chelyabinsk bronze plaque

[Martin Goff]

Hi all,

I posted a while ago asking for help in locating a source of cast iron
plaques that had been made to commemorate the Chelyabinsk meteorite fall.
Well after much searching and lots of use of google translate i have found
a source :-) Shout out to Karmaka meteorites, thanks Martin for your
assistance :-)

The foundry cast all sorts of items using the traditional 'Kasli' method
and are actually based in Chelyabinsk. The plaques are available in iron or
bronze. They are really nice in hand and look good when displayed next to
some Chelyabinsk specimens.

The link to their website is below:

(http://www.ural-antik.ru/index.php?ukey=search&searchstring=%D0%BC%D0%B5%D1%82%D0%B5%D0%BE%D1%80%D0%B8%D1%82)

And here is a link to some photos of my plaque:

(http://www.flickr.com/photos/94515040@N03/sets/72157635504830298/)

And lastly here is a link showing a Chelyabinsk family photo ;-)

(http://www.flickr.com/photos/94515040@N03/sets/72157635504845206/)

Enjoy :-)

Re: [meteorite-list] Chelyabinsk with Natural Hole...worth a look! / More Meteorites With Hole

[Galactic Stone & Ironworks]

Holy Meteorites Batman!

Who doesn't like a holey meteorite?

What I really like, are stones with holes, like Ruben's Chelyabinsk.
While any meteorite with a hole is rare, a stone with a hole seems to
be the rarest of the rare.  I've handled thousands of stony meteorites
(classified and unclassified), and I have only seen one holey stone
meteorite.

This one was a small unclassified NWA chondrite.  I sold it a few
years ago and have no idea where it is now.

[meteorite-list] Chelyabinsk: six months of eBay sales

[valparint]

Sorry about the previous post - itchy trigger finger.

I've been doing some similar record keeping for ebay sales and can add this 
about Chelyabinsk specimens >= 3 grams:

Through the end of March, the average cost per gram, including shipping, was 
about $35.

This declined steadily. For August sales, the figure is closer to $8.

Re: [meteorite-list] Chelyabinsk: six months of eBay sales

[Michael Farmer]

eBay is not the world market, and sadly these dealers are cutting their own 
throats, selling non-stop even after they are in the profit. Lunacy. There is a 
thing called market saturation, you can only sell so many of the same item and 
then your customers are tapped out.
Smart people would stop selling for a few years. 
These guys will sell out soon and then be crying as they have no more 
Chelyabinsk and the price rises. The same thing happened during Park Forest and 
Ash Creek, now try to find those things.
I have put thousands and thousands of Chelyabinsk in storage, will get them out 
in a decade or so. Bob Haag told me a story about Esquel, that after he bought 
the main mass, Al Lang and Ray  Myer and Blaine Reed bought a 50 kilo chunk 
that remained in Argentina, which they promptly sold for $1-2 gram back in the 
80s. Haag just pulled his from the market, waited until they sold it all, then 
popped back out and has made millions. They have none.

With hundreds and hundreds of chelyabinsk on eBay daily, how can the price do 
anything but go down? Quality has also gone down, you are seeing mostly after 
snowmelt material, low quality and ugly, that affects price as well. One can 
not just look at the price and say that the market is "in ruin". 90% of my 
customers are not on eBay or interested in the endless scams and problems that 
come with buying or selling there.

Re: [meteorite-list] Chelyabinsk: PRICING six months of eBay sales

[Michael Blood]

Hi Valparint & all,
Interesting. I examined the Xl file and what I saw was that
Such decline was related to % of fusion crust, size, etc.
I believe the average price originally (after the first blush) was
About $20 to $25/g and now, FOR THE SAME QUALITY  & SIZE
A few "bargains" can be had, but the price is still close to what it was,
Just a lot more weathered and/or broken specimens - not the 99% to 100%
Fusion crusted black beauties.
I am close to sold out so I have no horse in this race - just that
the real "shift" seemed to me to be more about much more poor quality
Material with much lower prices is now available.
Best regards, Michael

Re: [meteorite-list] Chelyabinsk: six months of eBay sales

[Adam Hupe]

Interesting, I guessed it would be down to $5.00/gram by the end of September.  
The only way it will get to the $5.00/gram mark is if the Russians offer it in 
bulk in Denver.  Then I predict the price will stabilize six months after that.


Kind Regards,

Adam

Sorry about the previous post - itchy trigger finger.

I've been doing some similar record keeping for ebay sales and can add this 
about Chelyabinsk specimens >= 3 grams:

Through the end of March, the average cost per gram, including shipping, was 
about $35.

This declined steadily. For August sales, the figure is closer to $8.

Re: [meteorite-list] Chelyabinsk: six months of eBay sales

[Galactic Stone & Ironworks]

Hi Richard,

Spot on and right.  Same here.  Buying directly from the finder cannot
be beat for provenance purposes.  It doesn't get better than that.
Buying directly from a finder who publicly documented their entire
trip, every step of the way (including the vodka hangovers!), is
priceless.  It's well worth an increased premium to have that extra
story, photos, and details that can only come straight from the
finder.  Good stuff there.  :)

In fairness, I have bought from middle-men and dealers also, and have
gotten some great deals.  But I really don't mind paying more for
having that extra documentation and provenance that only comes
directly from the finder.

Best regards and happy huntings,

MikeG

That is amazing work Robert, I would love to see it.
Millions were spent on Chelyabinsk worldwide, that's for sure.
The mexico event last week could easily have been just as large or larger 
based on the videos so far released, but it seems most likely the 
meteoroid skipped back out into space!
It would have been amazing to have had to massive events in the same year,

appeared to be an IMB, or anything else I thought relevant.

If enough people are interested in the spreadsheet, rather than email it

Having spent over 30 hours over the last 6 months compiling all this

point to mention it on the List. I think you'll find the master plot

this is the most detailed price history of a meteorite ever constructed.

Hi Rob,

This is awesome.  Some of the numbers are interesting, if not surprising.

Average cost per gram is about typical for OC falls in Russia - a
little less than US/Canada/Europe falls and more than most Saharan
falls.

However, given the global attention Chelya received and the massive
shockwave (a first of this scale in modern history, second only to
Carancas.), the price seems a like a bargain for collectors.  $11/gram
for an unprecedented fall - if the Chelya body had exploded lower in
the atmosphere, the effects would have been catastrophic.  Windows
blown out for miles.  Building collapsed.  Thousands of injured
witnesses. Captured world attention for months and is still getting
press.  It's gorgeous when cut.  It's gorgeous when fresh and uncut.
It's arguably a hammer fall - surely something was struck by that
widespread shower of stones, and if not, the shockwave damage should
qualify for collector "hammer" purposes.  This fall has everything
collectors want and it was a global wake-up call for the entire world
to be more cognizant of the other small asteroids/comets targeting our
fragile blue marble.

At $11/g, this is a steal.

Of course, as you said Rob, this number itself doesn't take into
account the notations you made about quality/type of material, and
this material shows a lot of faces - fresh, weathered, IMB lithology,
"regular" lithology, dual lithology, anomalous specimens (inclusions,
weirdness), cut and uncut.  I am guessing the $11/g number is seen
with a few lucky eBay snipers and/or the more weathered and less
attractive pieces.

Myself, I have paid up to $40 a gram for Chelyabinsk - depending on
the situation.  I paid $40/g for gorgeous beautiful uncut stones that
were almost-pristine and free of oxidation. I paid substantially less
for tiny crumbs or weathered frags.

22.1 kilos seems a bit small for a fall that likely produced much more
material on the ground than the eBay total suggests.  (who knows what
is sitting at the bottom of Lake Chebarkul, rotting in the chilly
muck.)  Of course, this is still a useful number because it can be

[meteorite-list] Chelyabinsk: six months of eBay sales

[meteorite-list] Chelyabinsk Meteorite May Have Collided with Another Body in Solar System

[Ron Baalke]

http://www.sci-news.com/space/science-chelyabinsk-meteorite-another-body-solar-system-01338.html

Chelyabinsk Meteorite May Have Collided with Another Body in Solar System
Sci-News.com
Aug 27, 2013 

According to a team of Russian scientists reporting today at the Goldschmidt 
conference in Italy, the Chelyabinsk meteorite either collided with another 
body or came too close to the Sun before it fell to our planet.

The researchers from the Institute of Geology and Mineralogy in Novosibirsk 
have analyzed fragments of the meteorite, the main body of which fell 
to the bottom of the Chebarkul Lake near Chelyabinsk on February 15, 2013. 
Although all of the fragments are composed of the same minerals, the structure 
and texture of some fragments show that the meteorite had undergone an 
intensive melting process before it was subjected to extremely high 
temperatures 
on entering the Earth's atmosphere.

"The meteorite which landed near Chelyabinsk is a type known as an LL5 
chondrite and it's fairly common for these to have undergone a melting 
process before they fall to Earth," said Dr Victor Sharygin, who is a 
first author of the study (an abstract has been published in the Mineralogical 
Magazine).

"This almost certainly means that there was a collision between the Chelyabinsk 
meteorite and another body in the solar system or a near miss with the Sun."

Based on their color and structure, the researchers have divided the meteorite 
fragments into three types: light, dark and intermediate.

The lighter fragments are the most commonly found, but the dark fragments 
are found in increasing numbers along the meteorite's trajectory, with 
the greatest number found close to where it hit the Earth. The dark fragments 
include a large proportion of fine-grained material, and their structure, 
texture and mineral composition shows they were formed by a very intensive 
melting process, likely to have been either a collision with another body 
or proximity to the Sun. This material is distinct from the "fusion crust" 
- the thin layer of material on the surface of the meteorite that melts, 
then solidifies, as it travels through the Earth's atmosphere.

The fine-grained material of the dark fragments also differs from the 
other samples as it commonly contains spherical "bubbles" which are either 
encrusted with perfect crystals of oxides, silicates and metal or filled 
with metal and sulfide.

Surprisingly, the scientists also found small quantities of platinum group 
elements in the meteorite's fusion crust. They identify these elements 
as an alloy of osmium, iridium and platinum, but its presence is unusual 
as the fusion crust is formed over too short a time period for these elements 
to easily accumulate.

"Platinum group elements usually occur as trace elements dispersed in 
meteorite minerals, but we found them as a nanometer-sized mineral (100-200 
nm) in a metal-sulfide globule in the fusion crust of the Chelyabinsk 
meteorite," Dr Sharygin said.

"We think the appearance of this platinum group mineral in the fusion 
crust may be linked to compositional changes in metal-sulfide liquid during 
remelting and oxidation processes as the meteorite came into contact with 
atmospheric oxygen."

Re: [meteorite-list] Chelyabinsk Russia Meteorite "smuggling" and Rob Elliot Newspaper Story

[Gary Fujihara]

Everyone is bashing the British press reports on all counts, but this is what I 
know about the early exportation of Chelyabinsk. Within days of the February 
15th fall, the Russian Duma Committee did declare exportation off-limits 
(seemingly to protect Russian scientists to have access to material for 
research) and the Ministry of Culture rejected all applications for meteorite 
exportation. 

At this point, at least one independent seller of Chelyabinsk was hiding the 
Russian meteorites in vintage analog vacuum tubes when shipping them out of the 
country. Others followed suit by hiding meteorites within macrame figures and 
other innocuous objects.

These bits of information were probably not supplied by Elliot, but any 
journalist could have ferreted them out, and they appear to be early reports as 
the reference to Elliot's specimen being "one of the only pieces of the Russian 
meteorite Chelyabinsk to have made it to the west…" is clearly inaccurate.

[meteorite-list] Chelyabinsk Russia Meteorite "smuggling" and Rob Elliot Newspaper Story

[drtanuki]

Graham and list, 
 I find it odd that the Guardian Newspaper "reporter" was able to pull the 
details of packaging the meteorites carefully hidden with electronic equipment 
for the "smuggling" through the mails out of thin air?  I would guess the 
British press reports about what they are told or do they just make it up as 
they go? 
Best Regards,  Dirk Ross...Tokyo

Great work, Svend! The insights provided into wind-shift influence on strewn 
field distribution are remarkable. A real boon to meteorite strewn field 
research. Congratulations, and thank you for making the results of your 
excellent work freely available to all. :-)

Thanks to everyone for your kind feedback.

Perhaps the most surprising result was that the combined weight of the 233 finds
submitted (recorded from mid-February to mid-June) was just 52.9 kg (52 find
locations were submitted without data on the respective masses).

Cheers

Re: [meteorite-list] Chelyabinsk strewnfield map and trajectoryprojection

[Matthias Bärmann]

What a marvellous result of your utmost challenging work, Svend, Karl.

The map embodies graphically the irresistable path of the bolide, aiming at 
least to the very heart of Lake Chebarkul - emphatically spoken.


It offers insights as well as an aesthetical "impact" of this breathtaking 
event.


Best as ever - Matthias

Re: [meteorite-list] Chelyabinsk - slickensides or shock planes?

[MEM]

Morning Jim   How, you ask? 


Take two large meteoroids and wack them together at incredible speeds.  What is 
not vaporized or pulverized will sheer and move in an opposite vector to 
relieve compressional forces where the two meteoroids "interfaced". The 
compression varies according to the macro surface: where there are ridges/bumps 
on one body, the other body at that junction will see more compressional force 
and where there are valleys one will see less compressional and vice versa.  
The rupture of the matrix is nature's way of balancing the competition for 
space and the kinetic energy vectors: the inertia thingy. We know it as equal 
and opposite reactions.  Since silicate is not elastic, it will break and areas 
of it will be displaced relative to the other side of the fracture. Since the 
rupture is rarely even, the two sides will grind against each other leaving 
skid marks all other things considered.

Both the energy and masses have to return to balance after the impact. 
Slickensides represent areas of the original body where sheer exceeds physical 
bonds and will be displaced to accommodate the compression forces(solids don't 
compress but they do respond to compressional forces)

Elton

Re: [meteorite-list] Chelyabinsk - slickensides or shock planes?

[Graham Ensor]

I'm not so sure this picture shows slickensides...if you look closely
at the picture there are veins of melt running from the black
areaI think it is just a break through one of the large melt
pockets that are evident in Chelyabinsk.it does have the look of a
slickenside but they are just paper thin black melt sheets scored in
one direction and would not have thicker melt veins coming from them.

Re: [meteorite-list] Chelyabinsk - slickensides or shock planes?

[Meteoriteshow]

Yes it is. A very famous meteorite that shows great slickensides is Zag
actually.

Have all a great day!

Does this help Jim?

To me, slickensides look almost like streaks, and yes, shiny.
Like my cat scratched it!  ;-)

Welp, I just need to see one up close. But in the mean time here is a
paper on the subject that may be of interest...
