Writeup from AMN 6(2):
Sample No.: EETA82600 Location: Elephant Moraine Field No.: 2956 Weight (gms): 247.1 Meteorite Type: Howardite
Physical Description: Carol Schwarz Some black pitted fusion crust occurs on one surface of EETA82600. The other surfaces are smooth and gray with small white and dark gray inclusions. Chipping revealed an interior that is gray with an indistinct whitish weathering rind. The inclusions present are small and not very obvious. Dimensions: 7 x 5 x 5 cm
Petrographic Description: Brian Mason The section shows a microbreccia of angular fragments (grains up to 2 mm across) of pyroxene (orthopyroxene and pigeonite) and plagioclase, in a matrix of comminuted pyroxene and plagioclase. Trace amounts of troilite and nickel-iron are present, and rare plagioclase-pigeonite clasts, up to 1.5 mm across. Microprobe analyses show a wide range in pyroxene compositions: Wo1-24, En33-77, Fs22-53; the grains with En >70 indicate the presence of a diogenitic component. Plagioclase shows a considerable range of compositions, An7-21. The meteorite is classed as a howardite and is possibly paired with EETA79006.
