Name: Mount Pratt 04401 This is an OFFICIAL meteorite name. Abbreviation: PRA 04401 Observed fall: No Year found: 2004 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 55 g
Macroscopic Description: Kathleen McBride
20-50% of the exteriors have thin, shiny patches of black fusion crust. The interiors are charcoal gray to black matrix with no metal visible.
Thin Section (,2) Description: Tim McCoy and Valerie Reynolds
The meteorites 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. PRA 04401 contains
particularly abundant CM2 clasts. Orthopyroxene compositions span a range of Fs16-60Wo1-3, although a single grain
of Fs1 was observed, presumably from the CM2 clast. The Fe/Mn ratio is ~30 and feldspar is anorthitic (An87-90). The
meteorites are howardites.
