Fact sheet
Description: 

12016 contains resorbed olivine crystals often included within pyroxene grains. Pyroxenes tend to be elongate (0.5 to 1 mm) and occur as complex intergrowths of augite and pigeonite. Plagioclase occurs interstitially, and is sometimes subpoikililitic. The groundmass of 12016 includes grains of fayalite, silica and phosphate in a cryptocrystalline matrix of devitrified glass.

The sample weighed 2028.3 grams before analysis. It has not been dated.
