| 摘 要： | 以地南金矿床位于力士山—新堡复背斜及其2条区域性大断裂之间。矿体受近NS向断层破碎带控制,呈板脉状、透镜状,主要赋存于德乌鲁岩体内接触带,为受断裂破碎带控制的岩浆后期热液矿床。容矿围岩主要为石英闪长岩,硅化、毒砂化、黄铁矿化和辉锑矿化与金矿化关系密切。文章着重对矿床地质特征进行了分析研究,探讨了成矿控制因素,对该区域或类似地区金矿找矿勘查具有指导意义。

Geological characteristics and ore-controlling factors of Yidinan Gold Deposit in Gansu |
| |
| Abstract: | Yidinan Gold Deposit is located in Lishishan -Xinbao anticlinorium and between 2 great regional faults.The orebody in form of lens and slaty veins mainly occurs in the inner contact zone of Dewulu rock mass and is controlled by NS trending faulted fracture zone.The deposit belongs to a postmagmatic hydrothermal deposit controlled by faulted fracture zone.The host rocks are mainly quartz diorite and gold mineralization is closely related with silicifi-cation,pyritization,arseno-pyritization and stibnitization.The ore-controlling factors are discussed based on the analysis of geological features,which is referable for the prospecting of gold deposits in this mining area and similar ones. |
