| 摘 要： | 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。

| Abstract: | Microfeatures and mineral chcmistry of the phenocrysts in the porphyries of Shaxi ore deposits have been studied. It is shown that the mineralizing materials of the porphyries comes from the upper manlfIe, contaminated by crlJst mass during ascending, and its melanes are rich in magnesiun and titanium; the material of barren porphyries comes from the deep crust and its rnelanes are rich in iron. The magma-crystallization envlronment of mineralized porphyries is also different from that of barren ores. |
