Ordinary chondrite (H5)
Find, 1947; 3.58 kg

A single meteoritic stone was recovered. Chondrules, clasts, and flecks of Fe-Ni metal are seen within a generally equilibrated matrix interrupted by obvious weathering. Compositionally, equilibrated olivine (Fa19) and low Ca-orthopyroxene are characteristic of the H-chondrite geochemical group. Mineralogically the meteorite consists primarily of olivine and pyroxene accompanied by minor troilite, and Fe-Ni metal. Accessory copper and ilmenite are also reported. Penokee is unusual in that it is one of the very few ordinary chondrites in which chromite wasnot observed by Ramdohr (1973).

The main mass is at the U.S. National Museum in Washington, DC (3.352 kg in 2017).
