Re: [meteorite-list] Carancas crater

[meteorite-list] Craters and impact pits revisited
SEARS D.W.G. (1978) The Nature and Origin of Meteorites (Adam Hilger Ltd., Bristol), pp. 25-26: Krinov (1966)* distinguishes between explosive craters, impact craters, and impact holes. The first correspond to major craters, where essentially complete vaporization of the meteorite occurs. Where meteorite fragments are occasionally found near such craters, they appear to have become detached from the meteorite before impact. Impact craters are non-explosive but, in the former case, the meteorite is destroyed mechanically, whereas in the latter, large specimens are usually found. For the major Sikhote Alin fall, where more than 100 craters and holes were made, Krinov has been able to show that the divisins may be made at 20 and 9 feet, but it is doubtful that these figures are generally applicable. *KRINOV E.L.

Re: [meteorite-list] Carancas crater
Ted and List, I'm happy to see you weigh in on this. Maybe this will stop the quibbling. I sense an odor of sour grapes in this thread anyhow. If one [or more] of our team managed to get there and survey the site, survive angry protestations, bring back a quantity for us to share, why quibble over terminology. Subsequent investigations corroborate earlier assessments and now this meteorite is being recognized for its historic import. HYPERVELOCITY is the watch word anyway.

Of course it is! In scientific terminology, impact pit is not acceptable. Let's review the facts: 1) The Carancas crater was produced by a hypervelocity impactor that excavated a deep hole and formed a raised rim of target materials (unconsolidated clastic debris). 2) Produced ejecta rays out 350 m from the crater 3) The event had sufficient shock energy to cause classic shock features in target quartz. 4) There is no size limitation for use of the term crater as long as the feature fits the accepted scientific constraints, e. g., formed by hypervelocity impact. LDEF (Long Duration Exposure Facility) flew in space for 5.5 years and studies of the facility skin showed thousands of craters as small as a few microns. Similar tiny craters have been found all over space shuttle vehicles. Apollo glassy spherules and rock samples show tiny impact craters as do several meteorite surfaces. In all of these cases, scientific reports used the term crater.

On the first page you will find the criteria for inclusion within this database (which is the most comprehensive and well-researched list on the planet). Sikhote-Alin is listed, Carancas is not (yet?). Also note Wabar and Haviland, both of which are termed craters and do fall within Adam's range of 5-20 m. The term impact pit is not listed in the Glossary of Geology (Jackson, 1997, 4th ed.), and is thus likely a loosely-used definition. Impact crater is listed in the Glossary and is defined as a generally circular crater formed either by impact of a projectile on a planetary surface or by an experimental hypervelocity impact of a projectile into solid matter...

It seems that some of the top scientists in the world think that it is a crater, perhaps you should enlighten them. Carancas is a crater, and I am not sure:), but I do believe that the impact of a meteorite created it, thus, I am still confused, but would that not tend to suggest that it is meteoritic? Adam, I think regardless of whether it is a common chondrite, the simple fact that it exists forces science to re-calculate its models for impact craters by chondrites. So Carancas is extremely important. I forsee papers written about Carancas for decades. There will be no roof built, the crater is already mostly destroyed (as I predicted that it would be, thanks to those of us who went there, at least some material was preserved).

Ok, I am now packing and sorting the last of the glass for shipment to China this evening, last call here folks, I still have about 20 kilos of the best material seperated for sales directly to list members, but I must send it all in about 5 hours, whatever does not sell now goes for making jewelery, so if you need cheap high quality tektites, now is the time to email me.

It doesn't matter to me what it is called. I'm just glad I bought a piece from Michael Farmer. Being new to meteorites, this is my first one.

Moritz Karl and I bought the other ~3 kilos he had, and most of that is sold now. I have less than 400 grams of material left for sale.

When you are in the crap, you make decisions on the spot, it is not as easy as sitting at your desk and typing emails.
