Name: Miller Range 090034 This is an OFFICIAL meteorite name. Abbreviation: MIL 090034 Observed fall: No Year found: 2009 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 195.6 g
35% of the exterior of this sample is covered with a dull olive green fusion crust. The remaining 65% is broken surface which consists of gray to olive green fine-grained matrix with fine cracks throughout. Features visible in the matrix include four white clasts that range in size from 2-5 mm, several 1-2 mm white clasts, and two 15-20 mm orangish-tan areas. The interior of this sample consists of a gray, fine-grained matrix with 1-2 mm white clasts throughout.
Thin Section (,2) Description - Cari Corrigan, Tim McCoy and Linda Welzenbach
The section consists of an extremely fine-grained matrix with isolated, large (up to mm-sized) mineral grains and fine- to coarse-grained anorthosite and basaltic clasts in all size ranges up to 3 mm. Microprobe analyses reveal olivine of Fa36-43, pyroxene in a wide range of compositions from pigeonite Fs23-41Wo4-6 with intermediate and more FeO-rich compositions, and plagioclase of An97. The Fe/Mn ratio of the pyroxene averages ~58. The meteorite is a basalt-bearing anorthositic regolith breccia.
