Writeup from MB 90:

San Pedro Jacuaro            19°46′N, 100°39′W

Estado de Michoacan de Ocampo, Mexico

Fall: 1 December 1968

Ordinary chondrite (LL6)

History: In December 1968, Jose Dimas Bautista of San Luis Potosi, Mexico, heard a loud “airplane type” sound while working outside the mines in the Sierra Madres mountains near San Pedro Jacuaro. A search recovered a 460 g mass from a fresh hole in the sand. He kept it in his possession until July 2003, when he brought it to the attention of Robert Cucchiara of Alameda, California, who recognized it as a meteorite.

Geochemistry: (P. Sipiera, Harper, K. Cole, Univ. Illinois) Olivine (Fa27.7), pyroxene (Fs23.2Wo2.0).

Classification: Ordinary chondrite (LL6); S2, W0.

Specimens: A 20 g type specimen is on deposit at PSF. Robert Cucchiara holds the main mass.
