甘肃天水黑沟金矿地质特征及找矿前景浅析
|
摘要
甘肃天水黑沟金矿床位于北秦岭、中秦岭构造带接合部位,属北秦岭柴家庄—庞家河金及多金属成矿带上;区域商丹深大断裂在矿区通过,是区内的重要导矿、导热构造,为成矿物质迁移富集提供了重要的条件;热液来源与印支期柴家庄二长花岗岩的侵入作用有关;矿床为较典型的中低温热液型矿床;从区域地质背景、矿区地质特征、含矿建造及深部钻探等多元信息综合分析,认为该矿区具有较好的找矿前景。
Heigou gold deposit is located at the junction of the northern Qinling and middle Qinling tectonic belts, belonging to the chaijiazhuang-liangshan and multi-metallic metallogenic belts in the northern Qinling. The deep fracture in the "S" type region is an important mineral and thermal conducting structure in the region, which provides important conditions for the migration and enrichment of metallogenic minerals. Hydrothermal sources are related to the intrusion of Erchang Granite in Chajiazhuang during the Indian period. The deposit is a typical low temperature hydrothermal deposit. According to the comprehensive analysis of multiple information such as regional geological background, geological characteristics of the mine area, the construction of the mine and deep drilling, the mine area has a good prospect of prospecting.
