Name: Grosvenor Mountains 17112 This is an OFFICIAL meteorite name. Abbreviation: GRO 17112 Observed fall: No Year found: 2017 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 16.3 g
Very dark red-brown possible fusion crust that is fractured with orange rust spots covers about 30% of exterior while exposed areas are weathered with a dark red-brown varnish though some spherical inclusions are visible. Fresh interior is a fine-grained matrix that is weathered to a dark orange-brown color with metal inclusions throughout.
Thin Section Description (,2) - Cari Corrigan, Tim McCoy
The section shows an aggregate of chondrules (up to 1 mm), chondrule fragments, and pyroxene grains in a matrix of about 30% metal and sulfide. Chondrules contain moderate to significant abundances of olivine. Weathering is modest, with staining of some enstatite grains and minor alteration of metal and sulfides. Microprobe analyses show the olivine is Fa0.5 and pyroxene is Fs0-1. FeNi metal contains 2.7 wt.% Si. The meteorite is an EH3 enstatite chondrite.
