Tong'an-Baishuidong lithium district (Wutang granites)
North-western Jiangxi, eastern Jiangnan Orogen (Qiankeng and Dagang areas), China
Magmatic (Ni-Cu-PGE, carbonatites)Li
- Type
- Lithium-bearing rare-metal granite
Granite-type lithium district related to the Ganfang intrusive suite (Ganfang, Guyangzhai, Wutang and Baishuidong plutons). The Wutang granites, highly fractionated S-type two-mica monzogranites dated at 145.8 ± 1.0 Ma (monazite), derive from melting of old crust (TDM2 1488 to 1553 Ma) in a compression-extension transition linked to Palaeo-Pacific subduction. Indicative coordinates.
