嘉峪关阴洼沟金矿地质特征及成因探讨

Geological characteristics and genesis of yinwagou gold deposit in Jiayuguan

阴洼沟金矿是甘肃省嘉峪关市发现的一重要的金矿床,褐黄色碎裂构造蚀变岩、灰绿色及黄绿色碎裂构造蚀变岩是改矿的主要的矿石类型,文中结合实践对阴洼沟金矿地质特征进行分析与阐述,详细研究该矿控矿地质要素,探讨该矿成矿地质特征,总结认为,阴洼沟金矿成矿过程中明显受控于区内的张-压扭性断裂构造,这些张-压扭性断裂构造明显控制着矿床规模、矿体形态和矿化强度等。下面对嘉峪关阴洼沟金矿地质特征及其成因进行详细分析与探讨,希望能对区内同类型矿床的寻找,提供一些指示作用。

Yinwagou gold deposit is an important gold deposit discovered in Jiayuguan City,Gansu Province.Brown yellow cataclastic structural altered rock,gray green and yellow green cataclastic structural altered rock are the main ore types for ore transformation.In this paper,the geological characteristics of yinwagou gold deposit are analyzed and elaborated,the ore controlling geological elements are studied in detail,and the metallogenic geological characteristics are discussed The oreforming process of yinwagou gold deposit is obviously controlled by the tension compression shear fault structure in the area,which obviously controls the deposit scale,ore body morphology and mineralization intensity.The following is a detailed analysis and discussion of the geological characteristics and genesis of the yinwagou gold deposit in Jiayuguan,hoping to provide some indications for the exploration of the same type of deposits in the area.
