Ordinary chondrite, (H6)
Found, 1939; 6.2 kg
A Mrs. Hyatt sent a sample to the Nininger Laboratory of an odd-looking rock which had been plowed up in a largely rock-free field. Polished specimens reveal chondrules, Fe-Ni metal, and fractures within a reddish and sometimes blackened weathered matrix. Compositionally, equilibrated olivine (Fa20) and low Ca-orthopyroxene ('bronzite') are characteristic of the H6-chondrite geochemical group. Mineralogically the meteorite consists in the main of olivine and pyroxene with troilite, and Fe-Ni metal. Accessory chromite and ilmenite are found. The meteorite has not been studied extensively, but its fusion crust was sufficiently intact to be part of a study of isotopic fractionation within meteoritic fusion crusts.
The H-group (relatively high in total iron) chondrites are the largest group of ordinary chondrites and represent ~40% of classified meteorites. The H6 petrologic type represents ~25 % of the H group.
Like many meteorites collected by Harvey Nininger, the main mass (of the first stone) is now at the Arizona State University Center for Meteorite Studies in Tempe (1.3812 kg in 2016).
What's in a name? "Ovid (b)", a separate smaller 860 g H5 chondrite was found later (1943), but not formally recognized as a separate meteorite until 2005.
