Sample No.: MAC87320

Location: MacAlpine Hills

Weight(g): 16.2

Field No.: 4651

Dimensions (cm): 3x2.5x1.3

Meteorite Type: C2 Chondrite

Macroscopic Description: Carol Schwarz

The meteorite is covered by reddish-black weathered, polygonally fractured fusion crust. A small amount of salt is visible. The interior is black with white and rusty clasts/chondrules plainly visible.

Thin, Section, (,2) Description: Brian Mason

The small section consists almost entirely of large chondrules, up to 4 mm across, in a dark matrix which contains abundant metal grains, concentrated on chondrule margins; only a small amount of sulfide is present. Most of the chondrules are of granular olivine and polysynthetically twinned clino-enstatite; one small melilite-spinel inclusion was noted. The matrix appears to consist largely of phyllosilicates. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa1-30, mean Fa6; pyroxene, Fs1-7. The meteorite is tentatively classified as an unusual C2 chondrite; it resembles Renazzo in texture and in the abundance of metal.
