| 摘 要： | 对川西北哲波山金矿区内出露的中 -酸性岩脉、岩株的类型、化学成分、地质特征以及微量元素、同位素、稀土元素等特征进行了研究 ,指出印支晚期和燕山早期的岩浆岩均属钙碱质岩系列 ,均起源于幔壳混源区 ,原始岩浆在成分上和演化上又存在着一定的差异性。岩浆岩为成矿提供了一定的物质基础。

| Abstract: | There are many granite-porphyry veins and granodiorite stocks in the Zhebo gold deposit. The magmatite features, which include the type, chemical composition, geological feature, trace elements, and isotopes, REE, etc. in the district, are described in this paper. The research results indicate that Late Indosinian and Early Yanshanian magmatites are of alkali-lime series. The magma originated from the intermediate belt between the crust and the mantle. The primary magmas showed some differences in composition evolution. The magmatite have probably provided metallogenic elements. |
