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

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

Re: [meteorite-list] Chelyabinsk Meteorite Sheds Light on Dinosaur Extinction Mystery
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. Larry > This is an interesting theory. But, how does Chelyabinsk completely > rule out a carbonaceous KT impactor?

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

[meteorite-list] Chelyabinsk Meteorite Sheds Light on Dinosaur Extinction Mystery
NEWS RELEASE FROM THE PLANETARY SCIENCE INSTITUTE FROM: Alan Fischer Public Information Officer Planetary Science Institute 520-382-0411 520-622-6300 fisc...@psi.edu 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.

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.

[meteorite-list] Chelyabinsk Meteorite May Have Collided with Another Body in Solar System
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." __ Bibliographic information: Sharygin V et al. 2013.

My question is, with some of the historic meteorites I have, can over time, the strength at which a LL or L or even a H meteorite increase over time, due to oxidation and or rusting? Why I ask is because is because I have two meteorite samples that fell in 1803 and both are from France, but two different falls and are both L6. One sample is is less magnetic than the other. The one that is stronger has about the same attraction and pull to a H7 Forest City meteorite. All three meteorites come from top dealers and collectors, so I know the authenticity is genuine, but it seems some stones can have anomalys within, when tested with magnets. Has any other listers noticed this, and if so, why would this happen? I have also heard that some dealer has devised a full proof test to test stoney meteorites to see if they are LL L or H or HH, or did I just make up HH :) > >Shawn Alan >IMCA 1633 >ebay store >http://www.ebay.com/sch/imca1633ny/m.html >http://meteoritefalls.com/ > > >- Original Message - >From: Graham Ensor >To: Count Deiro >Cc: Peter Scherff ; meteorite-list@meteoritecentral.com >Sent: Saturday, March 16, 2013 6:24 PM >Subject: Re: [meteorite-list] Chelyabinsk meteorite > >Hi Countstrange that yours do not have any of the brown crust or >other surface features common in most from the fall that were picked >up within days. > >Graham > >On Sat, Mar 16, 2013 at 10:01 PM, Count Deiro wrote: >> Peter and List >> >> All nine Chelyabinsk/Chebarkul individuals that I have purchased from three different foreign sources resemble themselves.

None but a few that I've seen so far show more than the smallest impact marks and those display a typical grey chondritic, almost Portland cement color. Most landed on snow so have remained pristine. Heavier pieces will be recovered when the ice and snow melt. They are strongly attracted to a neo magnet and set off a detector easily, so I'm a little curious about the initial classification I've heard. Is LL6 S1 W1 and named Chebarkuhl..correct?

Re: [meteorite-list] Chelyabinsk meteorite
Hello Graham and Count and the rest of the Listers By chance with any of the people on here with multiple samples do you have photos of them grouped together to compare the bunch. Also, I think someone said Mike Farmer had posted an image/s of the them grouped together, is there a link, cause I missed that posting. Count/ when you tested the chelyabinsk fragments with a magnet, were they all consistent on how they stuck to and pulled from the neo magnet for the most part? I also have a question for the List about the magnet test. I have a small rare earth magnets which they are strong, but not super super strong. My question is, with some of the historic meteorites I have, can over time, the strength at which a LL or L or even a H meteorite increase over time, due to oxidation and or rusting? Why I ask is because is because I have two meteorite samples that fell in 1803 and both are from France, but two different falls and are both L6. One sample is is less magnetic than the other. The one that is stronger has about the same attraction and pull to a H7 Forest City meteorite. All three meteorites come from top dealers and collectors, so I know the authenticity is genuine, but it seems some stones can have anomalys within, when tested with magnets. Has any other listers noticed this, and if so, why would this happen? I have also heard that some dealer has devised a full proof test to test stoney meteorites to see if they are LL L or H or HH, or did I just make up HH :) Shawn Alan IMCA 1633 ebay store http://www.ebay.com/sch/imca1633ny/m.html http://meteoritefalls.com/ - Original Message - From: Graham Ensor To: Count Deiro Cc: Peter Scherff ; meteorite-list@meteoritecentral.com Sent: Saturday, March 16, 2013 6:24 PM Subject: Re: [meteorite-list] Chelyabinsk meteorite Hi Countstrange that yours do not have any of the brown crust or other surface features common in most from the fall that were picked up within days.

Re: [meteorite-list] Chelyabinsk meteorite
Hi List, I am still waiting on my first piece to arrive. I'll report my impressions, for what that is worth, after it gets here. I had the opportunity to purchase as little or as much material as I could afford, but I elected to purchase only a small crusted fragment for now. I am eventually in the market for a few whole crusted peas for my personal stash and a couple of friends, but I am holding off on that purchase until the market stabilizes some. Once the dust settles and newness wears off, we'll see the price come down. Hopefully Mike leaves some choice stones for the rest of us. LOL. ;) I was impatient enough to rush out and buy a "place holder" for my falls collection, but I'll wait a little longer before buying something that is for keeps. :) Having said that, that photo on the meteorite picture of the day was drool-inducing - all those delicious little perfect peas. Talk about a pea-lovers full serving. Give peas a chance! (Pultusk eat your heart out) Best regards, MikeG -- - Web - http://www.galactic-stone.com Facebook - http://www.facebook.com/galacticstone Twitter - http://twitter.com/GalacticStone Pinterest - http://pinterest.com/galacticstone RSS - http://www.galactic-stone.com/rss/126516 - On 3/16/13, Peter Scherff wrote: > Hi, > > I think the characteristics I described are seen one "larger" (over > 20 grams) specimens.

[meteorite-list] Chelyabinsk meteorite
Hello Peter, Count, List, > Has anyone else noticed these or other > interesting characteristics of this meteorite? As far as I know its preliminary classification is LL5 (S4; W0). As with Millbillillie, quite a few Chelyabinsk meteorites seem to be flight-oriented or at least flight-marked. I have a hunch that this has something to do with the entry / flight / explosion dynamics. Maybe the violent disruption of the original meteoroid (the spectacular, double cloud trail!) caused numerous fragments to be "propelled" into an almost or quasi-stable flight orientation when the meteoroid plunged into and hurtled through the denser layers of the atmosphere.

[meteorite-list] Chelyabinsk meteorite
I have had an opportunity to see samples of the Chelyabinsk meteorite. I think that these stones are almost as distinctive as the fireball was spectacular. Many samples have deep fractures. Many samples have patches of reddish fusion crust. The reddish crust may be secondary crust. It formed on broken surfaces or perhaps in the lower portions of regmaglypts. The reddish crust is smoother than the primary crust. Some samples have a brownish "dusty" appearance. Despite being freshly collected.
