Writeup from AMN 4(2):
Sample No.: RKPA80224 Location: Reckling Peak Field No.: 1291 Weight (gms): 8.0 Meteorite Type: Unbrecciated Eucrite
Physical Description: Roberta Score Thin, shiny black fusion crust covers five surfaces. One surface is a fracture surface. Areas devoid of fusion crust contain white crystals with dark inclusions. When this achondrite was chipped, fine-grain material was apparent between the white crystals. Some oxidation is present. Dimensions: ~3.5 x 1.5 x 1.0 cm.
Petrographic Description: Brian Mason The section shows an ophitic intergrowth of pigeonite and plagioclase, with accessory amounts of tridymite and opaque minerals; the average grain size of pyroxene and plagioclase is about 1 mm. Fusion crust is present on one edge of the section. The pyroxene and plagioclase crystals are somewhat granulated and show undulose extinction. A little limonitic staining is present in one area of the section. Microprobe analyses show pigeonite with an average composition of Wo10Fs54En36; some grains show exsolution lamellae of augite with composition Wo44Fs26En30. Plagioclase ranges in composition from An85 to An91, with a mean of An89. The opaque minerals are troilite and titanian chromite (TiO2 13-15%). The meteorite is an unbrecciated eucrite (pyroxene-plagioclase achondrite). | ||||||||||||||||||||
