Writeup from MB 83:
Talampaya Argentina Fell ~1995 Achondrite (eucrite) Stories circulating among meteorite dealers tell of a meteorite that fell in Argentina, producing a sonic boom that scared a mountain climber. The climber eventually found the meteorite somewhere down range. The location of the fall may have been in San Juan or La Rioja province. One 1421 gram stone was recovered, and sold in the United States. Classification and mineralogy (P. Warren, UCLA): monomict breccia with a cataclastic texture, containing some millimeter-sized unbrecciated clasts; pyroxenes, En58.6–60.0Wo1.2–1.6 and En40.5Wo45.7; plagioclase, An89–95, mean An92; chromite contains ~1.26 wt% MgO; very low in incompatible trace elements; bulk Cr content (3400 ppm) typical of cumulate eucrites. Oxygen isotopes (M. Prinz, AMNH): typical eucrite composition. Specimens: main mass being sold by commercial meteorite dealers; 530 g, AMNH. | ||||||||||||||||
