Sample Number MIL 13079
Newsletter 38,2
Location Miller Range
Field Number 21106
Dimensions 3.6 x 2.2 x 1.0
Weight 11.57
Original Classification Eucrite (Brecciated)
Mineral Composition (%Fa &  %Fs)
Ferrosilite (mol%): 24-62
Macroscopic Description - Mitchell Haller
70% of the exterior has glossy jet black fusion crust and minor fractures. Areas without fusion crust are gray with some oxidation. The interior is gray matrix with black and white inclusions and minor weathering.
Thin Section Description (,2) - Cari Corrigan, Tim McCoy
The section consists of a coarsely comminuted pyroxenes (up to 1 mm) and feldspar (up to 0.5) mm set in a fine-grained matrix. Polyminerallic clasts are scarce, with most fragments being monominerallic. Mineral compositions are homogeneous with orthopyroxene (Fs62Wo2), with lamellae of augite (Fs24Wo47), and plagioclase (An88Or0.5). The Fe/Mn ratio of the pyroxene is ~28. The meteorite is a brecciated eucrite.
