甘肃金矿地质特征及其启示

Geological Characteristics and Inspiration of Gold Deposits in Gansu Province

甘肃金矿资源丰富,类型众多。按照成矿区域及地质背景,甘肃金矿可分为北山、祁连、西秦岭和摩天岭4个成矿带。本文对4个金矿成矿带的地质背景和其中金矿的地质特征进行了总结,提出未来西秦岭和北山金矿成矿带是最有利的找矿潜力区,以期对甘肃金矿成矿规律的认识和找矿工作提供参考。

Gold resources in Gansu are abundant and their types are various.Considering the metallogenic mechanisms and geological characteristics,gold deposits in Gansu can be divided into four metallogenic belts,namely Beishan,Qilian,West Qinling and Motianling.In this paper,the geological background of the four gold metallogenic belts and the geological characteristics of the gold deposits are summarized,and it is put forward that the West Qinling and Beishan gold metallogenic belts would be the most favorable prospecting potential areas in the future.It may provide reference for the understanding of the metallogenic rules and prospecting work of gold deposits in Gansu.
