Ordinary chondrite, (H4)
Found, 1927; 3.9 kg

A single 'odd-looking' stone was recovered ~8 km south of Ulysses by one L.P. Carter. After his death, the entire stone was obtained by the Nininger Laboratory. Inspections reveal distinct chondrules (up to 4 mm in diameter) and chondrule fragments within a grayish matrix. Olivine (Fa17) and low Ca-pyroxene ('Bronzite') are characteristic of the H-chondrite geochemical group. Dominant olivine and pyroxene along with Fe-Ni metal are readily observed. Troilite grains of quite variable size are often intermingled with the Fe-Ni metal. Accessory chromite, ilmenite, and copper are also reported. Surprisingly, Ramdohr (1973) did not report troilite — suggesting that some sections of the meteorite have experienced severe weathering as can also be seen in photographs. A reported 1.91 Ga U,Th/He age and a 5.2 Ma cosmic ray exposure (CRE) age provide some initial chronological markers to constrain the actual timing of the mineralogical record.

The H-group chondrites (relatively high in total iron) are the largest group of ordinary chondrites and represent ~40% of the well-classified recovered meteorites. The H4 petrologic type represent ~ 1/4th of the total group. Like many meteorites collected by Harvey Nininger, the main mass (1.2271 kg) remains at the Arizona State University Center for Meteorite Studies [2016 report].
