Re: [meteorite-list] Smallest Meteorite

Revelstoke had a recovered mass of about 1 g. Yamato 8333 is listed as being 10 mg, which is only 1% as massive as Revelstoke. Alan Rubin Quoting Adam Hupe raremeteori...@yahoo.com: I thought Revelstok Canada which was just a smudge in the snow held the record. Best Regards, Adam

Re: [meteorite-list] Sutter's Mill BSE - two more

I just received two small chips this afternoon but haven't had a chance to look at them yet. But I have seen the images that Sasha Krot, Mike Zolensky and Carl Agee made. The rock is clearly a breccia. Sasha's chip has a CM2.0 clast surrounded by slightly less altered material, probably

Re: [meteorite-list] Asteroid Or Comet Sutters Mill

CM chondrites are also ubiquitous. The most abundant foreign component of the lunar soil is chemically similar to CM chondrites. If i recall, many fireballs also seem to be CM like, although other list members would be better able to address this point. More CM chondrites would be in

Re: [meteorite-list] Solar system mystery 'solved'

Many people who have seldom looked at chondrules have come up with imaginative theories of how they formed. The source of heat is just one aspect of the problem. Most chondrules appear to have been heated multiple times, an observation difficult to reconcile with this new model. Many

Re: [meteorite-list] Classifying iron meteorites

The main classifier of irons is John Wasson at UCLA who uses neutron activation analysis to get the trace element compositions. Quoting Robert Beauford robertbeauf...@rocketmail.com: What is the 'standard' instrument used for classifying iron meteorites by trace element composition and who

Re: [meteorite-list] Question - meteorites returned from Moon

The sample described in the McSween paper is Bench Crater. There are also a few iron fragments that are probably iron meteorites, but they have not been officially designated. There are probably additional small meteorites waiting to be discovered. Quoting tracy latimer

Re: [meteorite-list] Question

There are two named meteorites returned among the Apollo samples: Bench Crater and Hadley Rille. Quoting pshu...@messengersfromthecosmos.com: I don't guess I have ever seen this anywhere. Does anyone know if any Apollo Lunar returned rocks were Meteorites? Any answers out there Pete

Re: [meteorite-list] meaning of breccia

Just a clarification of the word breccia. A breccia is a rock that contains distinct chunks or clasts. If the clasts are all of the same lithology and the host is the same lithology as the clasts, the rock is a monomict breccia. If the clasts or hosts are from different meteorite

Re: [meteorite-list] Full Circle With Correo

An interesting aside: Correo and Suwanee Spring were the first meteorites I classified. I went looking for more specimens one hot summer day back in 1979 or 1980 but found nothing. Alan Rubin Quoting Robert Woolard meteoritefin...@yahoo.com: Hi List,   I hope you will indulge me with

Re: [meteorite-list] Fwd: Re: CAI and chondrules

Jeff brought up an important point on which that I would like to elaborate. A few chondrules may sport a peculiar feature that may have important constraints on how those few chondrules formed. The problem is in generalizing. I may feel that those few chondrules are a Rosetta Stone that
