| 摘 要： | 对四川西部乡城-稻城-得荣中带地区矿点进行岩石化学特征分析及典型矿床(点)对比,该区域内浅成岩体属于亚碱性岩体,又分为钙碱性系列和拉斑系列(TH)2大类.从微量元素角度判别了相关矿点的构造背景并预测了相关矿点的成矿潜力.处于火山弧环境的足鸡顶地区的花岗细晶岩具有与热液有关的成铜矿潜力;红卓、那郎地区具有很好的找铜矿潜力;措岩体具有一定钨锡矿的成矿潜力.

| Abstract: | This paper analyses the petrochemical features of the deposits of the Middle Daocheng- xiangcheng-derong area in west Sichuan. The hypabyssal granites in the area are subalkaline rocks and include tholeiitte and calc-alkaline rocks. Using trace elements,we distinguish the tectonic background of the granites and forecast the minerogenic potentiality of some related deposits. The granite aplite in Zujiding area generated in a volcanic arc environment have the are prospective for hydrothermal copper.There is also some copper potential in Hongzhuo, Nalang, and Haocaichu areas. The rocks in the Hongcuo area have potential for tungsten-tin mineralization. |
