Writeup from AMN 19(2):
Macroscopic Description: Cecilia E. Satterwhite
Fifty percent of the exterior of this carbonaceous chondrite is
covered with fractured black fusion crust. Flow lines are present
on the fusion crust on some surfaces. Areas without fusion crust
are dull and brownish gray in color. The interior reveals a black
fine grained matrix with mm-sized gray inclusions. Thin Section (,2) Description: Brian Mason The section shows sparse chondrules, up to 0.9 mm across, some irregular aggregates, and numerous small silicate grains in a dark brown to black matrix. The silicate grains are almost entirely olivine near Mg2SiO4 in composition, with a few more iron-rich grains. A little pyroxene near MgSiO3 in composition is present. The matrix appears to consist largely of iron-rich serpentine. The meteorite is a C2 chondrite. | ||||||||||||||||||||||||
