Writeup from MN J20:
Y981670
Lodranite

The section shows an equigranular texture with lots of 120° triple junctures. Constituent minerals include olivine, low-Ca pyroxene, plagioclase, Fe-metal, and troilite. Mafic minerals are generally clean, but some grains have small inclusions of opaques. Rims of Fe-metal are in many cases replaced by weathering products. Mineral compositions are olivine: Fa9.4-11.7; pyroxene: Fs11.6-13.1; and plagioclase An18.6-22.8.
