对沙溪斑岩铜（金）矿矿区有关岩体斑晶矿物的显微特征和矿物化学研究显示：含矿斑岩成岩物质主要源于地幔，但在岩浆上侵过程中受到壳源组分混染，其暗色矿物富Mg、Ti；无矿斑岩以壳源为主，暗色矿物富Fe；含矿斑岩与无矿斑岩结晶动力学环境亦有所差别。
The microscopic characteristics and mineral chemistry of the porphyry minerals related to rock mass in the Shaxi porphyry Cu (Au) ore deposit show that the diagenetic material of the ore-bearing porphyry is mainly derived from the mantle, but is affected by the crust source component The dark mineral is rich in Mg and Ti. The ore-free porphyry is dominated by crust and the dark mineral is rich in Fe. The crystallization kinetics of ore-bearing porphyry and ore-free porphyry are also different.
