Writeup from MB 110:
Cargo Muchacho Mountains (b) 32°55.260’N, 114°45.920’W California, United States Find: 2009 Dec 31 Classification: Ordinary chondrite (H4) History: On December 31, 2009, while searching in the watershed of the Indian Pass Wash for additional meteorites in the Cargo Muchacho Mountains (CO3) strewn-field, a single complete-individual stone with relict fusion-crust was found right next to where Robert Verish had parked his truck. Physical characteristics: A single, shield-shaped dark-brown stone; somewhat oriented. The side that was in contact with the ground is stained orange, while the top-side has a desert-varnished patina, which is indistinguishable from a relict fusion-crust. A cut surface reveals an interior with small, matrix-supported chondrules of various colors. Petrography: (A. Rubin, UCLA) Chondrules moderately abundant (500±50 µm). Sample composed of olivine, low-Ca pyroxene, troilite, Fe-Ni metal, and Fe-oxides. Geochemistry: Olivine (Fa18.0±0.1 n=7); Ferrosillite (Fs 16.2Wo1.6 n=9); low-Ca Pyroxene (Fs6.9Wo44.8 n=8). Classification: Ordinary Chondrite (H4) Specimens: 4.3 g at UCLA; main mass with Verish. | ||||||||||||||||||||||||||||||||||||||
