Writeup from AMN 37(1):
Sample Number DOM 10092
Newsletter 37,1
Location Dominion Range
Field Number 17207
Dimensions 2.4 x 2.0 x 1.3
Weight 8.40
Original Classification LL chondrite (impact melt)
Mineral Composition (%Fa &  %Fs)
Fayalite (mol%): 17-28; Ferrosilite (mol%): 7-22
Macroscopic Description - Cecilia Satterwhite
The exterior has fractured black fusion crust with some oxidation. The interior is light gray with some darker gray heavily weathered areas along the edges. Some metal is visible.
Thin Section Description (,2) - Linda Welzenbach, Pamela Salyer and Tim McCoy
The section exhibits two textures; one side is a fine-grained, melt-textured matrix of olivine and pyroxene (1-10 microns) with fragments of mineral grains (200-300 micron grain size) and the other, chondrules and chondrule fragments with abundant fractures. The mineral compositions are slightly unequilibrated; olivine is Fa17-28 and pyroxene is Fs7-22. The meteorite is an LL chondrite impact melt.
