摘要
甘肃省脉石英分布较分散,其中肃北县马鬃山一带脉石英分布较多。本文重点分析了肃北县大三羊井一带脉石英地质特征,区内脉石英主要赋存在敦煌岩群变质岩及二长花岗岩、辉绿岩中,探讨了脉石英成矿地质条件,认为大西井南、大三羊井东地区具有一定的找矿潜力。
The distribution of vein quartz is scattered in Gansu province, especially in Mazongshan, Subei county. In this paper,the geological characteristics of vein quartz in Dasanyangjing area, Subei county are analyzed. The vein quartz mainly occurs in metamorphic rocks of Dunhuang group, monzogranite and diabase, and the geological conditions of vein quartz mineralization are discussed, it is considered that the south area of Daxijing and the East area of Dasanyangjing have certain prospecting potential.
