They were formed by mixing of the partial melting graniticmagma of crust-derived material and mantle-derived basic magma.
岩石主要由幔源岩浆与中下地壳物质部分熔融形成的花岗质岩浆的混合形成的。

Research indicates that the main ore-controlling factors are intrusion of graniticmagma, multiple activities of regional faults and greisenization.
研究认为花岗岩浆的侵位、区域性断裂的多次脉动作用及蚀变作用是区内钨锡矿形成的重要控制因素。

The earlier units contain abundant mafic micro-enclaves, and the petrographic study of the enclaves indicates the crust-mantle mixing origin of the graniticmagma.
