Name: Miller Range 05062 This is an OFFICIAL meteorite name. Abbreviation: MIL 05062 Observed fall: No Year found: 2005 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 23.8 g
Macroscopic Description: Cecilia Satterwhite and Kathleen McBride
30-40% brown/black fusion crust is on the exteriors with polygonal fractures. The interiors are tan to gray in color and are friable. No metal is visible. Black and white inclusions and odd shaped clasts of various colors are visible.
Thin Section (,2) Description: Tim McCoy and Valerie Reynolds
The sections are so similar that a single description suffices. The sections show a groundmass of comminuted pyroxene and plagioclase
(up to 0.5 mm) with fine- to coarse-grained basaltic clasts ranging up to 5 mm. Fine-grained clasts, presumably impact melt in origin,
are observed. Most of the pyroxene is orthopyroxene and pigeonites with compositions ranging from Fs29-57Wo1-7, although augite of
Fs40-60Wo24-40 is found. The Fe/Mn ratio is ~30 and feldspar is anorthitic (An90-92). The meteorites are howardites.
