Writeup from AMN 17(1):
Sample No.: EET92025; 92026 Location: Elephant Moraine Dimensions (cm): 4.0 x 2.5 x 1.5; 3.5 x 2.5 x 1.5 Weight (g): 18.4; 17.0 Meteorite Type: Eucrite (brecciated)
Macroscopic Description: Carol Schwarz Both fragments are similar in appearance with fusion crust covering 40-50% of their exterior surfaces. The fusion crust is black and very shiny in places. The interiors of both are a similar tannish-gray color and medium-grained. 92026 contains several 1-2 mm sized white plagioclase inclusions.
Thin Section (EET92025,2; 92026,2) Description: Brian Mason The sections are so similar a single description will suffice; the meteorites are probably paired. They show a brecciated texture, with gabbroic clasts up to 3 mm across and pyroxene and plagioclase grains up to 0.6 mm in a comminuted groundmass of these minerals. The pyroxene is pigeonite with a moderate range in composition: Wo10-17, Fs42-55, En28-47, and clustered around Wo13Fs49; plagioclase composition is An88-94; a silica polymorph, probably tridymite, is present in small amounts. The meteorite is a monomict eucrite (brecciated).
