    GEOLOGICAL CHARACTERISTICS AND PROSPECTING INDICATORS OF THE LINGYUAN-FUXIN GOLD METALLOGENIC BELT IN LIAONING PROVINCE

    • 摘要: 凌源-阜新金矿成矿带是辽西及辽宁省至关重要的金成矿带.区内出露的各时代地层较齐全,与成矿关系最密切的为建平群小塔子沟组.构造运动发育从太古宙到中生代均有较大规模的构造活动,同时这些构造运动也控制了岩浆岩的侵入和金矿的形成与分布.成矿带内发育含金石英脉型金矿和次火山热液型金矿两种类型的金矿.通过对区域地质背景、典型矿床特征分析,总结了凌源-阜新金成矿带的金矿的赋矿层位、构造对金矿的控制作用及侵入岩与金矿的时空关系等3个方面的找矿标志.

       

      Abstract: The Lingyuan-Fuxin metallogenic belt is a significantly important gold metallogenic zone in Liaoning Province, outcropped with various formations, among which the Xiaotazigou Formation of Jianping Group has the closest relation with gold deposit. Tectonic movements developed from Archean to Mesozoic Eras with large-scale structural activities, which controlled the magmatic invasion and the formation and distribution of gold deposits. There are two types of gold deposits in the area, i.e. auriferous quartz vein type and subvolcanic hydrothermal type. Based on analysis of regional geological background and typical deposit characteristics, the author summarizes the ore prospecting indicators of host strata of gold, structural controls of deposits and the spatiotemporal relation between intrusive rocks and gold deposits.
