Fact sheet
Description: 

The texture of 15636 could be described as microgabbroic because of its coarse grain size. Anhedral, elongate pyroxene reach 3mm in length, plagioclase is 1 to 2mm, and larger embayed olivine phenocrysts are scattered throughout. Residual phases include cristobalite, fayalite, troilite, ilmenite, ulvospinel and glass. Chromite and silicate liquid inclusions are found in olivine. Ilmenite exsolution in ulvospinel is observed.

The sample weighed 336.7 grams before analysis and has not been dated.
