Permian peralkaline, peraluminous and metaluminous A-type granites in the Panxi district, SW China: Their relationship to the Emeishan mantle plume

Numerous Permian granitic intrusions (plutons) in the Panxi region, SW China are spatially and temporally associated with the Emeishan large igneous province (ELIP). Granites from the 260 Ma Panzhihua and Taihe plutons are peralkaline (ASI = 0.76–1.12; Na + K/Al = 0.78–1.2) and have high Fe⁎ values (0.92–0.99) with negative Eu anomalies (Eu/Eu⁎ = 0.22–0.98). Contrasted with the peralkaline plutons, syenites from the 260 Ma Woshui pluton are...
