[meteorite-list] Carancas crater - 8 months later
Hello list, last week I visited the impact site in Carancas, Peru for my very last time. I´m heading back to Germany soon... I found the crater covered with a tarpaulin. After more than eight months since the impact it is pretty much eroded, the rims are much shallower than at my last visit on september 26, 2007. The water inside the crater ist approx. 30 cm deep, the crater bottom is completely shoaled. Although local authorities had claimed to preserve the crater in novermber 2007, obviously not very much has happend since then. There are 4 concrete pillars surrounding the crater, approx. 1,5 meters high, that ought to be the basis for a roof that was supposed to protect the crater from the heavy rainfall in the rainseason. However, it looks very much as if these construction works hav been stopped some time ago. As I write in my report, the structure of these pillows looks very similar to to the fragile character of the Carancas meteorites... There have been some diggings in the vicinity of the crater, it was explained to me that they are to redirect the flow of surface water. My guide (who was the same guy that brought me there on my first visit on september 22) told me that sometimes tourists came to Desaguadero to visit the crater. On the way there I was offered some meteorites. I found that most of them were just dust from mother earth, but among the dust were indeed some tiny meteorite fragments! I took the fragments and left the dust for the other tourists :-) You can find some fotos and my report (in german, but I mentioned the interesting part in this email) on my webblog: http://www.kosmologs.de/kosmo/blog/himmelslichter/chile-2008/2008-06-05/8-monate-danach-besuch-am-meteoritenkrater-von-carancas Best regards fom Peru: Jan -- Das Universum expandiert?

Re: [meteorite-list] Carancas crater

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.

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.

NWA 3133 was instrumental in demonstrating that finding groups for orphaned stones using oxygen isotope plotting for parent-body provenance purposes is feasible. This is the only reason why I can see the metachondrite issue coming up in the case of GRA 06128/9 which seems to be more evolved. A neat stone, yes, but the outrageous claims that it is more fantastic than other equally interesting meteorites holds no water with me.

Re: [meteorite-list] Carancas crater
Hi Mike- Being _highly_ skeptical that the Carancas event was hypervelocity or crater forming was an entirely appropriate attitude during the first days. After all, not a year goes by that we don't get stories out of usually backwater places about fiery meteorites, destroyed homes, and craters. How often do these stories actually pan out? Once. It is precisely because Carancas appears to be unique that it is generating so much interest amongst meteor (and to a lesser extent, meteorite) researchers. It is also important to consider that there is no sharp distinction between a crater and an impact pit. Personally, I consider the presence of shock structures to push this into the crater category, but even so, identifying that evidence took several months.

Re: [meteorite-list] Carancas crater
Thanks for clarifying that Ted. Michael Farmer --- Ted Bunch [EMAIL PROTECTED] wrote: I am not sure why there is an argument about whether or not Carancas is an impact crater. 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.

Re: [meteorite-list] Carancas crater
Tim, it is somewhere in the 10 kilo range, giv or take a kilo. Of the 10 kilos I know of, about 6 kilograms was fine dust in baggies. Hans Koser has this material, he was trying to sell it at the Tucson show. 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. Calr Esparza in Tucson got around 1.4 kilo with Bob Haag, I bought all of Bob's share from him. There is about a kilo in a museum in La Paz, Bolivia. So around 12 kilos is my estimate of total material recovered.

Re: [meteorite-list] Carancas crater
Mike, I do not understand why this hashed out thread was started again by you as it is barely worthy of the bandwidth. I am not the one who started the impact pit versus crater debate months ago. I expressed my opinion at the time so why am I being the target of this immature string about who is right or wrong? I conceded months ago that Carancas could be called a crater. My initial problem came from reading old books including some of Ninninger's works that tried to define some craters as impact pits. Apparently, unpublished modern terms define craters more precisely but a lot of haze still exists. It is not about who is right or wrong. It is about defining terms through debate. The tone of your posts is argumentative as far as I am concerned and not worthy of more posts as this subject has already been beaten to death. Lets just call it a muddy hole in the gound created by a meteorite and be done with it.
