Coolidge
Coolidge is a carbonaceous (C4-ungrouped) chondrite found in Kansas in 1937. According to Meteoritical Society classification, type-4 carbonaceous chondrites mostly have Mg/Si ratios near solar value, oxygen isotope compositions that plot below the terrestrial fractionation line, and abundant metamorphosed chondrules. At the Buseck Center for Meteorite Studies, collection curator and research professor Laurence Garvie deciphers […]
Camel Donga
Camel Donga is an achondrite found on the Nullarbor Plain of Western Australia in 1984. The word “donga” is a term for “campsite” in Australia.

Parnallee is an ordinary (LL3.6) chondrite that fell February 28th, 1857, in Tamil Nadu, India. Parnallee is a low-iron, low metal (LL) chondrite exhibiting abundant chondrules, un-equilibrated mineral assemblages, and a low degree of aqueous alteration. Over 77 kilograms of the Parnallee meteorite have been recovered to date. The overwhelming majority of meteorites recovered in […]
