Writeup from AMN 19(2):
Macroscopic Description: Robbie Ann Score
Shiny black fusion crust with well-developed flow lines covers
one half of this pretty eucrite. The other surface is broken and
shows minor oxidation. The interior has coarse grained graphic
intergrowths of plagioclase and pyroxene. Some brown oxidation
is scattered throughout. Thin Section (,5) Description: Brian Mason The section shows a granular aggregate of pyroxene and plagioclase (grains up to 0.9 mm). The meteorite is unbrecciated, but the individual pyroxene crystals have been granulated. Microprobe analyses show essentially uniform compositions; pyroxene, Wo2-6 Fs60-63; plagioclase, An89-90. The meteorite is a eucrite. | ||||||||||||||||||||
