Writeup from MB 104:
Yucca 034 34°44.1’N, 114°13.1’W Arizona, United States Find: 6 May 2004 Classification: Ordinary chondrite (H6) History: Jerry A. Baird found the stone on May 6, 2004. He donated it to Cascadia on March 9, 2013. Physical characteristics: Oriented stone covered with weathered fusion crust. Petrography: In thin section, the sample appears well integrated, but with readily discernable chondrules, consistent with a low type 6 grade. BSE imaging shows that olivine and pyroxene is equilibrated throughout the section. Numerous feldspar grains >50 μm across were observed. Weathering is uneven, but ~15-20% of metal and sulfide grains have been replaced, consistent with a W1 weathering grade. Most olivine grains show undulose extinction and one to two sets of planar fractures, but no melt was observed, indicative of shock stage S3. Geochemistry: (M. Hutson and A. Ruzicka, Cascadia) Olivine (Fa18.8±0.3, N=16), low-Ca pyroxene (Fs16.5±0.2Wo1.5±0.1En81.9±0.2, N= 12). Classification: H6 based on mineral chemistry and texture. Specimens: Cascadia holds 84.8 g in a single piece, in addition to two polished thin sections and a mounted butt. | ||||||||||||||||||||||||||||||||||||||
