Name: Miller Range 090032 This is an OFFICIAL meteorite name. Abbreviation: MIL 090032 Observed fall: No Year found: 2009 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 532 g
The exterior surfaces of all three nakhlites have patches of black, wrinkled fusion crust. Areas without fusion crust have vugs. The interior broken faces are coarse grained and possess a crystalline, granular texture ranging from green to black.
Thin Section (,2) Description - Cari Corrigan and Linda Welzenbach
The sections are dominated by lathy to equant clinopyroxene that reaches 2 mm in maximum dimension. Mesostases occupies approximately 20% of the rocks and contains skeletal iron-titanium oxides. Clinopyroxenes have core compositions of Fs22Wo43 with rims reaching Fs49 Wo34. Olivines were observed in all three sections, are equant to subequant, and have slight alteration/oxidation along fractures. Olivine grains, which range between 0.5 and 1 mm, have core compositions of Fa57 and rim compositions of Fa89. Many olivines contain inclusions of mesostasis. Rare feldspars exist with compositions of An20-28 and Or11-14. These meteorites are nakhlites. These meteorites are similar enough that one description will suffice. They are also similar to and likely paired with, MIL 03346.
