金沙江—哀牢山岩带富碱侵入岩的成矿专属性

METALLOGENIC SPECIALIZATION OF ALKALINE—RICH ROCKS IN SHAJIANG—AI LAOSA BELT

金沙江-哀牢山富碱侵入岩带的矿化类型有:(1)Cu-Mo;(2)Pb-Zn多金属;(3)Au;(4)Mo-Cu;(5)稀有稀土金属矿化。富碱侵入岩的岩石类型和岩石化学成分与矿化类型之间存在明显的成矿专属性,其酸度和碱度是影响和控制矿化类型的主要因素,利用代表岩石酸度和碱度的变量能有效地区分富碱侵入岩的矿化类型。

The mineralization types of alkaline-rich rocks in An Shajiang-Ai Laosa belt are divided into five groups:(1)Cu-Mo; (2) Pb-Zn multiple metal;(3) Au; (4)Mo-Cu; and(5)Rare and Rare earth element metal mineralizations. There is a specialization relationship between the mineralization and alkaline-rich rocks. The acidity and alkalinity of alkaline-rich rocks are the major factors of affecting and controlling the mineralization types of these rocks, and they are efficaciously used to distinguish the mineralization types of al-kaline-rich rocks.
