Ordinary chondrite, weathered (L6)
Find, 1939; 93.5 kg
A single much-weathered meteoritic stone was recovered. The primary minerals, olivine (Fa23) and orthopyroxene ('hypersthene'), are compositionally representative of the L chondrite geochemical group. Ramdohr (1973) identified the normally expected kamacite, taenite, troilite, and chromite in material provided by Harvey Nininger. The L6 chondrites are the most abundant type of ordinary chondrites with 9773 confirmed and named stones listed at the Meteoritical Bulletin Database in early 2017. Concho is its 26th most massive member. However, the absence of significant additional reports for such a large meteorite in the readily available literature suggests that weathering may have compromised the meteorite's usefulness in scientific studies.
The main mass [at least 758 g in 2000] has been at the American Museum of Natural History in New York. Arizona State University [129.4 g in 2016] is one of several institutions with very modest-sized samples.
