Writeup from MB 105:

Yucca 036        34°42.845’N, 114°10.697’W

Arizona, United States

Find: 2006 Oct

Classification: Ordinary chondrite (L6)

History: Found by Dennis Asher in the "Buck Mountains 002 find area," and later donated to Cascadia.

Physical characteristics: Brownish weathering patina and remnant fusion crust patches occur on rough exterior surfaces.

Petrography: Well integrated chondritic texture visible optically and in BSE imaging. Plagioclase feldspar grains are >50 μm across, indicative of a type 6 chondrite. A large igneous-textured clast is visible along one edge of the section. Silicates in thin section are stained brown, with about 25% of the metal+sulfide weathered to form hydroxides, suggesting a W2 weathering grade. A shock stage of S3 is indicated by the prevalence of undulose extinction and planar fractures in olivine grains.

Geochemistry: (M. Hutson and A. Ruzicka, Cascadia) Olivine (Fa26.1±0.7, N=16), low-Ca pyroxene (Fs21.4±0.1Wo1.8±0.1En81.9±0.2, N= 12).

Classification: L6 based on mineral chemistry and texture.

Specimens: Cascadia holds 15.9 g in a single piece, in addition to two polished thin sections and a mounted butt.
