    STRATIGRAPHIC GEOCHEMISTRY OF PERMIAN STRATA IN THE CENTRAL DA HINGGAN MOUNTAINS AND ITS METALLOGENIC SIGNIFICANCE

    • 摘要: 二叠纪海相火山沉积岩系是大兴安岭中段出露的主要基底地层,是铜多金属矿床的主要赋矿围岩,其中成矿元素Cu、Pb、Zn、Ag、Sn均具有较高的丰度值,是形成矿床的重要物质来源,而不同矿床类型的时、空分布与早二叠世古构造沉积环境密切相关

       

      Abstract: The principal strata exposed in the central sector of the Da Hinggan Mountains are the Permian marine volcanic sedimentary series,which constitutes the main host rocks of copper polymetallic deposits.It has higher abundances of the ore forming elements Cu,Pb,Zn,Ag and Sn and thus is the important source of major ore forming substances.The spatial temporal distribution of different deposit types is closely related to the Early Permian tectonic sedimentary environment.
