延边复兴—杜荒岭金矿化区控矿规律与找矿方向

The metallogenic regularity and ore-seeking direction of Fuxing-Duhuangling gold mineralization district, Yanbian

复兴—杜荒岭金矿化区与中生代火山岩浆活动有关。主要控矿条件为小岩株状石英闪长玢岩(次火山岩),其中寄生的隐爆角砾岩筒及外围裂隙中赋存着金矿体;石英闪长玢岩体受东西向断裂(带)与近南北向断裂交汇部位火山机构中心控制,横向上具有等间距分布规律,构成本区控矿重要的构造条件。通过对九三沟等金矿床调查研究,总结了矿化区内控岩控矿条件及找矿标志,确定了区内找矿靶区和找矿方向。

The gold mineralization district of Fuxing-Duhuangling mineralization district is relative to the activity of Mesozoic volcanic magma. The main control condition is quartz diorite-porphyrite with the shape of small rock stub （ subvolcanic rocks）, among the parasitic rubblerack tube and the off-lying crack, the gold orebody occurs. The quartz diorite-porphyrite body is subjected to volcano organization center which is around the crossing point of the east-west fracture （zone） and the south-north fracture, equidistant in transverse direction ,and it is the important tectonic condition of mineralization in this area. By doing the research to the Jiusangou gold deposits, the gold orebody control condition and indicator in the mineralization area are generalized, and the ore-seeking target and direction are determined.
