Macroscopic Description - Kathleen McBride, Cecilia Satterwhite | |
The exteriors of these carbonaceous chondrites are black with small patches of purplish colored fusion crust. The interiors are a black, platy or shale like matrix with small (< 1 mm) white specks. | |
Thin Section Description (,2) - Tim McCoy | |
We tentatively describe these as paired given their find sites in a linear array ~4 km in length. The MET 0063X meteorites exhibit the shaly texture seen in other MET 00 meteorites, particularly the MET 00431 grouping (AMN Vol. 24, #2), with which these are spatially associated. The sections consist of a few small, unaltered chondrules (up to 1 mm), mineral grains and CAIs set in a black matrix. Olivine compositions are Fa0-41; orthopyroxene is Fs1-7. The meteorites are CM2 chondrites. |
