Thin Section Description (,2) - Cari Corrigan, Tim McCoy, Linda Welzenbach | |
The meteorite is an equigranular aggregate (0.5 mm grain size) of olivine and pyroxene in a metal-rich matrix, with lesser plagioclase, metal, sulfide, chromite and schreibersite. Plagioclase occurs interstitially to mafic silicates. Olivine (Fa8), low-Ca pyroxene (Fs11), high-Ca pyroxene (Fs4Wo44) and plagioclase (An14Or3) are homogeneous. The meteorite is a lodranite. |
