[meteorite-list] NWA CV3's & Dark Inclusions

[David Weir]

Hey Jeff,

I have a little info compiled that compliments what has been said so far 
(re: Allende):

In contrast to the generally held belief that the formation of
dark inclusions involved aqueous alteration/dehydration processes, it
has been demonstrated through a study based on the preferential
solubility of 7Li over 6Li that Li isotopic fractionation did not occur
within the dark inclusions to a greater extent than in the whole rock.
Therefore, a history of aqueous processing and dehydration for Allende
dark inclusions is not evident (Sephton et al, 2006). It has also
been demonstrated through fabric analysis that DIs, CAIs, and matrix
components were all accreted together prior to the common
impact/gravitation compressional forces that produced the observed
preferred orientation (Watt et al., 2006).
