Writeup from MB 102:
Diamond Valley 002 (DV 002) 39°57.318’N, 115°56.285’W Eureka County, Nevada, United States Found: 14 May 2011 Classification: Ordinary chondrite (H6) History: A single stone was found by Mr. Richard Kimbell on the Diamond Lake bed north of Eureka, Nevada, on May 14, 2011. One piece of this stone was donated to Cascadia in July 2011. Physical characteristics: The stone has a dark brownish-black exterior which represents a combination of weathered fusion crust and weathering rind, along with traces of a pink-colored caliche. The cut face is reddish-brown. Petrography: (M. Hutson, Cascadia) Recrystallized texture with few discernible chondrules. Twinned feldspar is present. An abrupt contact between two recrystallized lithologies is visible. One of the two lithologies is more heavily weathered, with >= 95% of the opaques replaced by terrestrial weathering product. The majority of the thin section is composed of a less weathered lithology with ~60-70% replacement, indicative of a W3 weathering grade. Olivine grains are relatively deformed, with most having mosaic extinction and one or more planar fractures, indicating an S4 shock stage. Geochemistry: Olivine (Fa20.8±0.7, n=18) and low-Ca pyroxene (Fs18.2±0.4Wo1.5±0.2, n=22). Specimens: A single mass of 16.2 g and 2 polished thin sections are on deposit at Cascadia. Mr. Richard Kimbell holds the main mass. | ||||||||||||||||||||||||||||||||||||||
