Newsletter 36,1
Location Miller Range
Field Number 22562
Dimensions 5.7 x 3.2 x 2.5
Weight 74.20
Original Classification Howardite
Mineral Composition (%Fa &  %Fs)
Ferrosilite (mol%): 15-47
Macroscopic Description - Cecilia Satterwhite
90% of the exterior has brown/black fusion crust with some gray matrix visible. The interior is a light gray matrix with minor oxidation and small white, gray, black and rusty grains.
Thin Section Description (,2) - Cari Corrigan and Andrew Beck
The section shows a groundmass of comminuted pyroxene and plagioclase (up to 0.5 mm) with large diogenitic pyroxene grains up to 3 mm. The section shows numerous impact features such as glass and sulfide clusters. Most of the pyroxene is orthopyroxene with compositions ranging from Fs15-47Wo2-45(most Wo2-10). Plagioclase is An86-94Or0-1. The Fe/Mn ratio of the pyroxene is ~28. This meteorite is a howardite.
