甘肃党河南山巴音金矿地质特征及成因

Geological characteristics and genesis of Bayin gold deposit in Dang Nan Shan, Gansu

甘肃党河南山巴音地层区域属华北地层大区,金矿资源储量有着很大的地理优势。本文主要研究甘肃党河南山巴音金矿地质特征及成因条件。基于甘肃成矿的地质环境,分析了巴音金矿的地质特征和成因,根据矿山元素的分布和地址环境对甘肃党河南山巴音金矿地质环境的勘查,调查结果发现巴音金矿的区内褶皱构造表现为矿区地层的展布由北到南从北东向转为北西向,呈帚状弯曲,具有多阶段,多来源等特点,矿床成因类型为中、低温热液蚀变碎裂岩金矿,有利的地质环境特征,提高了金矿生产率。

The stratigraphic area of the Bayan formation in the south of the Dang River in Gansu is a large area in the North China strata. This paper mainly studies the geological characteristics and genetic conditions of Bayin gold deposit in Gansu. Based on the geological environment of the Gansu mineralization, the geological features and causes of the Ba Yin gold deposit are analyzed. According to the distribution and address environment of the mine elements, the geological environment of the Ba Yin gold mine in Nanshan, Gansu is investigated. The investigation results show that the fold structure in the area of the Bayan gold mine shows that the distribution of the strata in the mining area is from north to south to the north from the north to the north. The west direction is a broom shaped bend with multiple stages and multiple sources. The genesis of the ore deposit is a medium to low temperature hydrothermal altered clastic rock gold, which is favorable for geological environment and improves the productivity of gold deposits.
