| 摘 要： | 研究区处于上黑龙江断陷盆地中段，中生代火山岩出露面积广泛，区内12处岩金矿床（点）均与中生代火山活动有关，塔木兰沟期和上库力期火山岩是成矿的岩体标志，3期火山岩均属碱性系列，以富Zr,Ti,Cr,P及轻稀土富集型为特征。硅化，绢云母化，绿泥石化，黄铁矿化，黄铜矿化。方铅矿化和褐铁矿化是找矿的蚀变标志，断陷盆地边缘和推覆构造边缘，火山带交汇部位，NE或NNE向断裂与其他方向断裂交汇部位以及火山机构周围的环状，放射状断裂是成矿的有利部位。

| Abstract: | The study area is located in the middle of the upper Heilongjiang fault basin,the distribution of Mesozoic volcanic rocks are extensive,and there are 12 rock gold deposits(points) related to Mesozoic volcanic activities.The volcanic rocks of Tamulangou and Shangkuli formation are ore body mark of the ore-forming.The three periods of volcanic rocks belong to the alkali-complex series and featured by rich Zr,Ti,Cr,P and light REE.The alteration remark of exploration include silicification,sericitization,chloritization,pyritization,chalcopyritization,galenitization and limonitization.The intersection part of faulted basins and nappe structure margins or volcanic belt,the intersection part of NE or NNE strike fault with others and ring-shaped and radial fault around volcanic mechanism are favorable sites for gold precipitated. |
