辽宁省桓仁县穷棒子沟斑岩型钼矿床地质特征及控矿因素

Geological characteristics and Ore-controlling Factors of the Qiongbangzigou Porphyry Mo Deposit,Huanren County of Liaoning Province

穷棒子沟钼矿床矿体受火山机构环状断裂构造裂隙所控制,三度空间上钼矿体围绕次生石英岩流纹斑岩体高角度并向内倾斜,其形态呈同心环状分布,矿体赋存在次生石英岩化流纹斑岩体及其外带火山岩中。通过对矿床成因进行分析,认为穷棒子沟钼矿床是与火山机构有关的斑岩型钼矿床。

Qiongbangzigou Porphyry Mo Deposit is affected by the circular fault structure fracture of volcanic apparatus. The Mo orebody circles the secondary quartzite rhyolite porphyry three-dimensionally and is tiled inward at a high angle. It is distributed in a concentric ring-shape. The orebody exists in secondary quartzite rhyolite porphyry and the volcanic outer zone. Through the analysis of genesis of the orebody,it is believed that Qiongbangzigou Mo Deposit is porphyry Mo Deposit related with volcanic apparatus.
