四川省主要铜“矿源层”及成矿旋回

SOURCE BED AND METALLOGENETIC CYCLE OF COPPER DEPOSITS IN SICHUAN

从地质找矿角度出发,按广义的“矿源层”概念,将省内四个Ⅰ、Ⅱ级构造含铜区内主要的与铜成矿有关的数十个地层层位,进行梳理分析,划分出原生和次生两类“矿源层”,并在此基础上尝试划分出铜的成矿旋回,探索其物质流向,从时、空演化上阐述成矿规律,并预测某些可能的成矿位置。

According to the source bed concept and form search for minerals, four tectonic-metallogenetic provinces and tens stratigraphic horizons concerned with Cu mineralization in Sichuan are classified into original and secondary source beds, on the basis of which, the present paper makes some attempts to determine the metallogenetic cycles, to probe into the source of the metal material, to set forth the metallogenetic regularity and to predict some Cu deposits.
