Hello List, I found the following abstract from the latest MetSoc meeting interesting. Having not read the GCA article by Wasson that was mentioned by Jeff, I was interested to read some further details on the subject, however brief. I assume this is what Wasson wrote about.
http://www.lpi.usra.edu/meetings/metsoc2002/pdf/5083.pdf It seems to me to give more credence to Jeff's (and Wasson's ?) statement ascribing the reduction of OCs to different parent body processes, rather than to an origin on a separate parent body - the latter proposal suggested in one post-Wasson, non-peer-reviewed paper.

Others were studied by: Wasson J. T., Rubin A. E., Kallemeyn G. W. (1993) Reduction during metamorphism of four ordinary chondrites. Geochim. Cosmochim. Acta 57 (8), 1867-1878. If memory serves, some of the meteorites discussed in this paper were Suwahib (Buwah), Willaroy, and Cerro los Calvos. There don't really form an "extension" of H chondrites. They are anomalous, and have seen different processes. jeff ______________________________________________ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
