| 摘 要： | 云南人头箐金矿位于北西向洱海-红河断裂与近南北向程海-宾川断裂夹持部位,区内赋矿围岩地层主要为奥陶系迎凤村组第三段(O2y3),岩性为薄层状粉砂岩、石英砂岩。构造以北东向和近东西向为主,北东向的响水断裂带是程海-宾川断裂南段的组成部分,多期次活动特征明显,是区内一级构造。近矿围岩蚀以钾长石化、硅化为主,其次为绢云母化和黄铁矿化,均与金矿化关系密切。该金矿类型为构造蚀变岩型金矿床。

| Abstract: | The Rentouqing Au deposit is situated in the delta between the NW-trending Erhai-Honghe fracture zone and the longitudinal Chenghai-Binchuan fracture zone.The Au deposit is hosted in thin bedded siltstone and quartz sandstone of the third Member of the Ordovician Yingfengcun Formation(O2y3).The deposit is characterized by wallrock alteration such as K-feldspathization,silicification,sericitization and pyritization in close relationship with Au mineralization.The deposit belongs to tectonic alteration type o... |
