甘肃省文县新寨金矿成矿地质条件分析

新寨金矿位于著名的"川甘陕"金三角地区,处于白龙江成矿带的玛曲―南坪金成矿亚带东段。文章系统总结了金矿地质特征和地球化学异常特征,研究了矿床的成矿地质条件及热液蚀变特征,得出了地层、岩石、构造、围岩蚀变及地球化学找矿标志。最后,提出了一些认识,以期指导矿区找矿工作的进一步深入开展。

An analysis of metallogenic and geological conditions of Xinzhai gold deposit in Wenxian of Gansu

Xinzhai gold deposit is located in the famous"Sichuan-Gansu-Shanxi"golden triangle area which is a part of the east section of Maqu-Nanping gold metallogenic sub-belt of Bailongjiang metallogenic belt. This paper systematically summarized the geological characteristics and geochemical anomaly features of this gold deposit,and conducted research on the metallogenic and geological conditions and characteristics of hy-drothermal alteration of the deposit.Strata,rocks,structures,wall rock alteration and clues for geochemical prospection are defined in this paper.At last,this paper put forward its understanding,so as to guide the further prospecting works in this mining area.
