摘　　要：甘肃西秦岭大桥金矿具有良好的成矿地质条件,矿产资源丰富,矿藏资源主要分布在石岩系同三叠系之间存在的不整合接触面上。矿藏资源整体上体现出了分布范围广,矿藏资源埋深浅,整体的品味较低。当前西秦岭地区已经成为了我国重要的金属矿藏地带之一,但对于该矿地质特征类型的研究不足,其大地构造背景、矿床特征、矿体特征、矿区构造特征、矿床地球化学特征的相关研究较为匮乏,基于此,本文对西秦岭大桥金矿的上述特征进行了系统全面的论述。The Daqiao gold deposit in West Qinling,Gansu Province has good metallogenic geological conditions and rich mineral resources.The mineral resources are mainly distributed on the unconformity contact surface between the stone series and the Triassic system.Mineral resources as a whole reflect the wide distribution range,shallow burial depth of mineral resources and low overall taste.At present,the West Qinling area has become one of the important metal ore deposits in China,but the research on the geological characteristics of the mine is insufficient,and the relevant research on its tectonic background,deposit characteristics,ore body characteristics,mining area structural characteristics and deposit geochemical characteristics is relatively scarce.Based on this,this paper systematically and comprehensively discusses the above characteristics of the West Qinling Daqiao gold mine.
