Qinghai, China<\/span><\/p>\n

Confirmed fall: 2016 Aug 24<\/span><\/p>\n

Classification: Ordinary chondrite (L5)<\/span><\/p>\n

History: On 24 August 2016, at about 21:00 local time, several nomads of Banma City, Qinghai province, saw a bright object flying from a southeasterly direction, followed by a loud explosion. The next day, the nomads searched in the direction of the explosion and found a black stone embedded in the ground in a small crater on a hillside.<\/span><\/p>\n

Physical characteristics: The stone is relatively flat and 32 \u00d7 23 cm and 18 cm thick. Fusion crust and regmaglypts are well preserved.<\/span><\/p>\n

Petrography: Chondrule outlines are obscure. The matrix displays a moderate to high degree of recrystallization. Poorly defined BO chondrules are 0.4-0.6 mm wide. All the feldspar grains are relatively small, less than 50 \u03bcm. Numerous FeNi metal and FeS grains are present.<\/span><\/p>\n

Geochemistry: (W. Hsu, PMO) Olivine, Fa24.0\u00b10.4 (n=14), range Fa23.2-24.8. Low-Ca pyroxene, Fa20.3\u00b10.5Wo1.6\u00b10.1 (n=10), range Fs19.7-21.4Wo1.5-1.8.<\/span><\/p>\n
