摘要
北秦岭西段地处秦岭造山带和祁连造山带的接合部位，是构造岩浆活跃地带，特别是中生代构造岩浆活动形成了该地段中生代构造岩浆带。北秦岭西段是金矿（化）集中的地带，控矿的主要因素可以归结为下列几个方面：①区域地质构造背景；②区域地球化学场；③构造断裂；④构造岩浆活动；⑤流体地质。这五种因素共同作用决定了金及相关元素的迁移富集，形成了规模不等、类型各异的金矿床及金矿化点。
Western section of the North Qinling is localited in juncture of the Qinling Orogenic beltwith the Qilian Orgenic Belt,and characterized by well-developed tectonomagmatism,especiallyMesozoic tectonomagmatism. Gold deposits and gold metallization are common i n the studiedarea. Chief controlling factors of gold deposits and gold metallization can be listed as the follow-ings:①regional geologic tectonic background,②regional geochemical field,③fracture,①tectono-magmatism,and⑤fluid geology.Migration and concentration of gold and its relative elements arecommonly controlled by the above-mentioned 5 factors.Thus,it led to form various scale and dif-ferent types of gold deposits and gold metallization.
