Writeup from MB 102:
Rosamond 34°49.676’N, 118°8.784’W
Kern County, California, United States
Found: 2012 June 9
Classification: Ordinary chondrite (LL3)
History: Found by Robert Verish on June 9, 2012, while he was searching for meteorites in an empty lot on the outskirts of the town of Rosamond.
Physical characteristics: Yellowish-brown tabular-shaped, weathered fragment of a chondritic stone. Through a thin, patchy relict fusion-crust, large chondrules which were flattened and are in a preferred-orientation, could be discerned easily with a hand-lens.
Petrography: (A. Rubin, UCLA): The rock has large chondrules, averaging about 600 μm in diameter, consistent with LL chondrites. The rock has a pronounced petrofabric.
Geochemistry: Fa13.5±11.0 (n=4), range Fa0.7-25.0; Fs15.7±12.1Wo0.8±0.6 (n=16), range Fs1.6-31.7; the low-Ca pyroxene Fs distribution has a broad peak between Fs23 and Fs32, consistent with a low petrologic grade LL chondrite.
Specimens: 3.45 g type specimen at UCLA; main mass with Verish.
