Nagornyj        47°22.95’N, 41°45.03E

Rostovskaya oblast’, Russia

Petrography: The meteorite mostly comprises chondrule fragments and a few whole chondrules 400-600 μm in diameter, surrounded by fine-grained crystalline matrix. The grains of FeNi metal (100-200 μm in size) are partly replaced by FeNi hydroxide, that also forms numerous thin veinlets in the meteorite. Olivine has weak undulatory extinction and irregular fractures; feldspar grains are up to 60 μm and have undulatory extinction. The minor phases are troilite and chromite.
