Hi Adam, I agree that third-hand Internet-based visual means are an extremely poor, unreliable, ineffective, and highly inappropriate method of classifying meteorites. But I also agree that it is fun.
Your scientific wild-assed guess and mine likely differ based upon our personal experiences with meteorites. So... are you willing to bet a margarita in Tucson on your guess? I am. Cheers, Martin On 7/18/06, Adam Hupe <[EMAIL PROTECTED]> wrote:
Hi Martin and All, I don not think images are a good way to ascertain classifications but in this case I took a S.W.A.G. at it in the interest of fun. I think the crust is wrong for a CO3 because virtually every sample of a CO3 I have seen has very fine contraction cracks, some do not even penetrate as deep as the matrix. These cracks show up in detailed images. These cracks are absent in the enhanced image provided by a List member taken from an article on the new fall. The color of CO3 type crusts is usually semi-gloss black, never flat black like the one in the image. In my opinion, the crusts are always uniformly thin on a CO3 and never velvet-like and patchy. I think many feel it is a CO3 based on the numerous very small chondrules and not the crust. I agree the chondrules are too small for an LL, CV, CR, CK or even an L. They are too numerous for a CM2 which are sparsely populated. This leaves only CO, H or Anom types as candidates. I picked an H type because I have seen examples with exceedingly small chondrules, velvet like flat black crusts and friable matrixes.
