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.
