Sixiangkou meteorite, Sixiangkou, Taizhou City, Taizhou Prefecture, Jiangsu Province, China

L6 Chondrite

The Sixiangkou Meteorite fell on June 15, 1989 near Sixiangkou town.

Microscopic examination shows that it is an olivine-bronzite chondritic meteorite composed primarily of olivine (40%), bronzite (32%), plagioclase (10%), kamacite (7%), troilite (6%) and some Ca-rich salite and cristobalite.
