Hi List,

Last night I heard something puzzling.

A collector/scientist that I know says that he read a paper published
by GSI that claims Katol is an H5 chondrite. I asked him for a link
to the paper or more info on it, and I am still waiting to hear back
on that.

In the meantime, this has me wondering. I have seen a lot of H5
chondrites over the years. I have seen fresh H5 falls and weathered
H5 NWA stones. I have never seen an H5 (or any H-chondrite) that
resembles Katol. I have a hard time believing that this meteorite is
an H. The pieces I have seen (many, ranging in size from crumbs to 2+
grams, whole and fragments) do not look like chondrites at all. I
have heard reports of specimens that have chondrules, but I have not
seen any. I also heard reports of a specimen that is entirely metal
and another one with crystalline inclusions. If those reports are
credible, and based on the green matrix and crystalline texture, then
I doubt this is an H-chondrite.

Does anyone have a link to this GSI paper or more info about it?

Best regards,

MikeG
