甘肃辛曲金矿床地质特征及找矿标志

GEOLOGIC FEATURES AND PROSPECTING INDICATOR OF XINQU GOLD DEPOSIT,GANSU PROVINCE

甘肃辛曲金矿位于甘肃省大水金矿田的西北部,属构造蚀变岩型金矿床。矿体受NNE向张扭性断裂控制,与印支期岩浆活动及脉岩有时空成因联系,具有矿体大,矿化均匀,物质组分简单的特征。文章在总结了矿床的地质背景、矿化类型、特征及富集规律的基础上提出了找矿标志。

Xinqu Gold Deposit,which is located in the northwest part of Dashui gold field in Gansu,is a low grade gold deposit of altered rock type controlled by structure.Under the control of NNE direction fold structures,its formation has relations with Indo-Chinese epoch igneous activity and vein rock from the point of space and time.It is characterized by large ore body,even mineralization and simple mineral composition.Based on the summary of geologic background,mineralization types and features,and rules of meta...
