Jiajika (JSD-1 scientific drill hole)
Western Sichuan, Kangding (Garzê), China
Magmatic (Ni-Cu-PGE, carbonatites)Li
- Type
- Lithium granitic pegmatite field (LCT type)
Largest hard-rock lithium deposit in China, in the southeastern Songpan-Garzê terrane; spodumene pegmatites around the Majingzi two-mica granite, in Triassic metasediments with Barrovian metamorphism. JSD-1 drill hole, 3211 m deep, about 1 km NE of the granite. Huan et al. (2023): magmatic tourmalines of granite and pegmatites from -9.49 to -7.06 ‰, differentiation by equilibrium crystallization and fluid exsolution; spodumene bodies concentrated between 5 and 150 m depth. Indicative coordinates taken from the district (X03 vein record).
