【摘要】 通过对新疆西天山金山金矿床勘探资料综合研究,识别出京希矿区存在火山塌陷构造与同生断裂耦和,对京希金矿床成矿过程中起着重要控制作用,造就了富大金矿体。不整合面+断裂+热液角砾岩是金山金矿床控矿的基本特征。根据控矿构造组合方式,发现3种构造控矿式样:矿体形态主要受控于不整合面的"伊尔曼得式",矿体形态受不整合面和南北向断裂联合控制的"巴拉克式"和矿体形态主要受控于火山塌陷构造和同生断裂控制的"京希式"。更多还原

【Abstract】 With the integrated study on the exploration data of west Tianshan Jinshan gold deposit in Xinjiang, the Jingxi mining area was identified to exist the coupling of volcanic collapse structure and contemporaneous fault, which was the controlling factor in the metallogenic process of the deposit and formed large and rich orebodies. Unconformity surface, fault and hydrothermal fluid breccia are the basic ore-controlling characters in Jinshan gold deposit. 3 types of structure ore-controlling forms are concluded, Yelmend type controlled by unconformity surface, Barak type controlled by unconformity surface and N-S faults, Jingxi type controlled by volcanic collapse structure and contemporaneous fault.更多还原
