| 摘 要： | 近年来在青海省祁漫塔格地区陆续发现了一系列斑岩-矽卡岩矿床,卡尔却卡铜多金属矿床是其中一个典型的矿床。通过对该矿床S、Pb同位素研究,结合前人研究成果与成矿岩石地球化学特征,认为该矿床的成矿物质来源为深源岩浆,同时也有壳源物质的混染,成矿物质具有壳幔混合的特点。

| Abstract: | In recent years, a series of porphyry-skarn ore deposits were found in Qimantag area, Qinghai Province in succession, the Karqak copper polymetallic ore is one of typical deposits among them. Through deposit S, Pb isotopic study, combined with previous research results and ore-forming rock geochemical characteristics, have considered that the ore-forming material source is from deep magma, also hybridized with crust materials, thus ore-forming materials have characterized by crust and mantle hybrid source. |
