Name: Miller Range 15468 This is an OFFICIAL meteorite name. Abbreviation: MIL 15468 Observed fall: No Year found: 2015 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 4.3 g
Exterior has 70% black fusion crust with frothy areas. Areas without fusion crust are black. The interior is a black matrix with white specks and minor oxidation.
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 Fa0.5-51, pyroxene is Fs2-12. Aqueous alteration of the matrix is substantial, but the chondrules are only modestly altered, apparently less so than those we group with MIL 15300, although this distinction may reflect the particular sections examined rather than real differences between these groups of meteorites. The meteorite is a CM2 chondrite.
