Writeup from AMN 37(1):
Sample Number DOM 10085
Newsletter 37,1
Location Dominion Range
Field Number 17216
Dimensions 3.0 x 2.0 x 1.5
Weight 18.15
Original Classification CR2 chondrite
Mineral Composition (%Fa &  %Fs)
Fayalite (mol%): 0-4; Ferrosilite (mol%): .7-1.65
Macroscopic Description - Kathleen McBride
The exterior of this CR2 has a patch of black fusion crust. The interior is rusty black with no visible features.
Thin Section Description (,2) - Linda Welzenbach, Pamela Salyer and Tim McCoy
The section exhibits a distinct lineation with a few small (100-300 microns) metal-rich chondrules and a few CAIs in a dark matrix of FeO-rich phyllosilicate. Polysynthetically twinned pyroxene is abundant. Small metal grains show “fizzed” texture and some silicates show mosaicism indicating moderate to strong shock. Silicates are unequilibrated; olivines range from Fa0-5, with most Fa1 and pyroxenes from Fs0-1Wo0-2. The meteorite is probably a CR2 chondrite.
