Macroscopic Description - Kathleen McBride | |
40% of this carbonaceous chondrite's exterior has thick purplish-black fusion crust with polygonal fractures. The interior is a dark gray to black color with a soft matrix. White to light gray chondrules are visible, <1mm in size. | |
Thin Section Description (,2) - Tim McCoy | |
This meteorite may be paired with the other MET 00 CM2 chondrites, but is a geographic outlier from that cluster. The section consists 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 Fs0-1. The meteorite is a CM2 chondrite. |
