小秦岭金矿田处于秦岭东西向复杂构造带与新华夏系第三隆起带交接部位。成矿地质背景主要是多种地质因素的复合，赋矿地层为多期变质变形的上太古宙太华群深变质岩系；控矿构造为东西向构造叠加北东向构造形成的斜网格状断裂系统，多期的构造一热事件使Au元素多次活化迁移富集成矿，具有较大的找矿潜力。
小秦嶺金礦田處于秦嶺東西嚮複雜構造帶與新華夏繫第三隆起帶交接部位。成礦地質揹景主要是多種地質因素的複閤，賦礦地層為多期變質變形的上太古宙太華群深變質巖繫；控礦構造為東西嚮構造疊加北東嚮構造形成的斜網格狀斷裂繫統，多期的構造一熱事件使Au元素多次活化遷移富集成礦，具有較大的找礦潛力。

The Xiaoqinling gold field occurs in a junction between the east-west trend Qinling complex structural belt and the third uplift of Neocathaysian, in which the geological settings for mineralization are composed of multiple geological factors and the ore-hosted beds are of multiple metamorphosed and deformed rocks of the Archean Taihua Group. Ore-controlled structures are of oblique fault system grid formed by superimposed east-west trend structures over north-south trend structures. Multiple phase tectonic and thermal events migrated and activated Au element and then enriched Au to form gold deposits.
