Writeup from MB 88:
Northwest Africa 2065 Morocco Found 2003 Achondrite (eucrite) A 58 g partial stone with 40 % crust was purchased in Erfoud, July 2003. Classification and mineralogy (T. Bunch and J. Wittke, NAU): monomict breccia of highly variable textures: fine-grained (< 1 mm) cumulate to subophitic with a partial overlay of metamorphic-granular (prominent 120 ° triple junctions). Cumulate areas: orthopyroxene host Fs58.2Wo2.1, exsolution lamellae, Fs25Wo45; plagioclase, An90.1, Cr/(Cr+Al) = 0.87; subophitic Ca-poor pyroxene, Fs62.3Wo5 with exsolved Fs27Wo43.9. This specimen probably sustained high shock levels, but shock indicators were mostly annealed-out during post-impact metamorphism. Very fresh, little apparent weathering. Specimens: type, 11.6 g NAU; main mass, Boswell. | ||||||||||||
