Notes:
# NASA data for MAC 02635 Weathering: C Fracturing: B Fs: 1-4 mol %
The exterior of this enstatite chondrite is rusty and shiny. The rusty black matrix is hard, brittle and contains dark gray to rusty chondrules/inclusions that are 1-2 mm in size.
The section shows an aggregate of chondrules (up to 2 mm), chondrule fragments, and pyroxene grains in a matrix of about 30% metal and sulfide. A few chondrules contain rare olivine. Weathering is moderate, with staining of enstatite grains and heavy alteration of metal and sulfides. Microprobe analyses shows the orthopyroxene is Fs₁₋₄ and metal contains 1.1 wt.% Si. The meteorite is an EL3 chondrite and is likely not paired with MAC 02837/02839.
