On February 11, 2012, a large meteor blazed across the sky over the mountains of rural China. This meteorite exploded in flight and the fragments showered across the remote mountainous region of Huangzhong County in Qinghai Province China.
Early recovered pieces of the fall show pristine black fusion crust in patches and the broken exposed matrix is virgin grey with shock veins and tiny flecks of metal. Later recovered specimens are starting oxidize in the snow. This meteorite is likely an L5 or L6 chondrite based on appearance and examination by local finders and authorities.
