摘要
驱龙铜矿发育多元素的岩石地球化学异常。成矿元素Cu、Mo、(Ag)异常强、规模大,异常与矿化区一致;伴生元素Au、Bi、Pb、As、Sb、Hg异常在Cu、Mo异常边部并套合产出的B Co、Ni Mn Zn的异常主要分布铜钼矿化带外侧。Na2O在矿化区显示负异常,K2O为正异常。从异常元素组合、水平分带性和贫Na2O、富K2O的成矿环境表明,矿床属典型的斑岩型铜矿地球化学特征,并受到了强烈的剥蚀。
Multielements primary geochemical anomalies are well developed in the Qulong porphyry CuMo deposit. The anomalies of oreforming elements Cu and Mo(Ag) are characterized by high intensity and large size, and accord quite well with the mineralization. The anomalies of associated elements Au, Bi, Pb, As, Sb and Hg are mainly distributed on both sides of the ore anomalies, whereas the anomalies of BCo and NiMnZn are spread around the ore anomalies. Na2O occurs as negative anomalies while K2O appears as positive anomalies in the ore district. Based on the above-mentioned association of elements, the horizontal zoning, and the Na2Opoor and K2Orich oreforming environment, it is considered that the Qulong Cu-Mo deposit is a typical porphyry deposit subjected to strong denudation.
