甘肃地区金矿地质特征与成因探讨

Geological characteristics and genesis of gold deposits in Gansu Province

甘肃地区有着非常广阔的地域面积,北山、祁连和秦岭等都历经长期复杂的地质构造演化历史,正是由于该区复杂的地质演化特征,促进来该区特征及不同成因金矿的形成。由于甘肃地区特殊的构造、变质、地层、岩浆以及岩性等控制,甘肃地区主要划分为北山、祁连和西秦岭等几个金矿成矿带。下文结合实践,对甘肃地区金矿地质特征进行详细的分析与探讨,并对甘肃地区金矿成因进行研究,希望能为该区地质找矿工作提供一定的参考作用。

Gansu Province has a very wide area.Beishan,Qilian and Qinling have experienced a long and complex geological structure evolution history.It is precisely because of the complex geological evolution characteristics of the area that the characteristics of the area and the formation of different genetic gold deposits are promoted.Due to the special control of structure,metamorphism,strata,magma and lithology,Gansu area is mainly divided into several gold mineralization belts,such as Beishan,Qilian and West Qinling.Based on the practice,this paper analyzes and discusses the geological characteristics of gold deposits in Gansu Province,and studies the genesis of gold deposits in Gansu Province,hoping to provide some reference for the geological prospecting work in this area.
