Bonnie Claire 003        37.229°N, 117.025°W

Nevada, United States

Find: 2020 Apr 3

Classification: Carbonaceous chondrite (CO3)

History: Found by Sonny Clary on Sarcobatus Flat, southern Nevada, on April 3, 2020.

Physical characteristics: A small (60.4 g) rounded black stone lacking fusion crust. The fresh interior revealed by cutting exhibits numerous fairly closely-packed, very small light colored chondrules and tiny metal grains.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Abundant well-formed, unequilibrated chondrules (apparent diameter 180±110 µm, N = 25), zoned olivine fragments, small AOA and sparse small, very fine grained CAI are set in a sparse fine grained matrix (~15 vol.%, reddish-brown in thin section) containing kamacite, taenite, troilite, pentlandite and Ti-free chromite. Some chondrules contain glass, whereas other chondrules contain plagioclase and nepheline (which has been observed in chondrules in other CO3 chondrites by Tomeoka and Itoh, 2005).

Geochemistry: Olivine (Fa24.6±24.1, range Fa1.3-64.9, N = 7; Cr2O3 in ferroan olivine 0.04-0.25 wt.%, mean 0.12±0.09 wt.%, N = 5), low-Ca pyroxene (Fs2.2±1.7Wo2.5±1.9, range Fs1.0-3.4Wo1.1-3.8, N = 2), diopside (Fs0.9Wo39.9), augite (Fs26.3Wo42.6), plagioclase (An27.6Or0.7; An78.3Or0.4; N = 2).

Classification: Carbonaceous chondrite (CO3, nepheline-bearing).

Specimens: 13.8 g including one polished thin section at UWB; remainder with Mr. R. Clary.
