Writeup from AMN 37(1):
Sample Number DOM 10077
Newsletter 37,1
Location Dominion Range
Field Number 17228
Dimensions 2.5 x 2.0 x 0.75
Weight 8.56
Original Classification CR2 chondrite
Pairing DOM 10077, DOM 10344, DOM 10467
Mineral Composition (%Fa &  %Fs)
Fayalite (mol%): 2-31; Ferrosilite (mol%): 14-23
Macroscopic Description - Kathleen McBride and Cecilia Satterwhite
These carbonaceous chondrites have brown/black fusion crust with oxidation haloes and rusty areas. The dark gray/black interior has abundant chondrules/inclusions of various sizes and color. Some metal is present.
Thin Section Description (,2) - Linda Welzenbach, Pamela Salyer and Tim McCoy
These sections exhibit small (100-300 microns), well-defined, metal-rich grains, and up to 2mm chondrules and a few CAIs in a dark matrix of FeO-rich phyllosilicate. Polysynthetically twinned pyroxene is abundant. Silicates are unequilibrated; olivines range from Fa2-33, and pyroxenes from Fs1-23Wo0-2. These meteorites are CR2 chondrites and are similar enough to be initially paired.
