白银厂矿区及外围区域地质背景、地球化学异常特征及找矿潜力

GEOLOGICAL SETTING,GEOCHEMICAL ANOMALY AND PROSPECTING POTENTIALITY IN THE BAIYINCHANG MINE AND OUTSKIRTS,GANSU PROVINCE

白银厂矿区及外围是北祁连铜多金属成矿带的主要地段。区内强烈多期次的火山活动、岩浆侵入及断裂构造,为该区提供了优越的成矿条件,而元素地球化学异常的密集特征又为进一步找寻新的矿床提供了有利的依据。区内最具找矿潜力的区域为石青硐—白银厂火山岩带、苏家湾—石青硐断裂带、白银厂矿区深部及附近地区。

Baiyinchang mine and its outskirts are important area in the northern Qilian metallogenic belt. Continental rifting, active volcanic eruptions and rupture structure provided excellent metallogenic factors. Concentrated element geochemical anomalies offered evidence for new deposit finding. The most favorable prospecting areas are Shiqingdong - Baiyingchang volcanic rock belt, Sujiawan - Shiqingdong fault belt, and deep and outside of Baiyingchang mine.
