Ordinary chondrite (H4)
Find, 1934; 11.1 kg
Several masses, including one found in 1964, were recovered. Composition of olivine [Fa19] and pyroxene ('bronzite' &/or 'clinobronzite') are characteristic of the H (relatively high bulk iron) ordinary chondrite geochemical group. Opaques were studied by Ramdohr (1973). A cosmic ray exposure age (CRE) of ~7.3 Ma has been obtained.
Moderate-sized masses have been held at Arizona State University in Tempe [1663.6 g in 2016], the Field Museum in Chicago [783.60 g in 2017], the TCU/Monnig Collection [3.4 kg in 2000], and elsewhere.
