Name: Miller Range 15489 This is an OFFICIAL meteorite name. Abbreviation: MIL 15489 Observed fall: No Year found: 2015 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 30.2 g
Most of exterior has brown/black fractured fusion crust, frothy on some surfaces. The exposed interior is black with white specks. Some evaporites and rust are visible. The interior is a black matrix with white specks, minor oxidation and evaporites.
Thin Section Description (,2) - Cari Corrigan, Tim McCoy
The sections consist of a few small chondrules (up to 0.5 mm), mineral grains and CAIs set in a black matrix; rare metal and sulfide grains are present. Olivine compositions are Fa1-52, pyroxene is Fs5-25. Aqueous alteration of the matrix is substantial, but the chondrules are extensively altered, apparently more so than those we group with MIL 15303, although this distinction may reflect the particular sections examined rather than real differences between these groups of meteorites. The meteorite is a CM2 chondrite.
