摘要：

洛坪金银铜矿普查区位于秦岭造山带东部，属韧性剪切带型金矿。普查区构造线总体上呈EW向展布，核桃园断裂贯穿其中部，为商丹断裂的次级断裂，它是在区域韧性剪切带基础上演化而成的脆性断裂带，该断裂控制着区内的地层分布，是北部下元古界与南部泥盆系的分界线。区内有岩浆侵入，构造发育，成矿条件极为有利。通过分析研究商州洛坪金铜多金属矿普查区成矿地质背景、地质特征、地球化学特征、矿化蚀变等特征，进行找矿潜力预测，推断该区具有良好的金找矿前景。

Abstract:

Luoping Au-Ag-Cu deposit is located in the eastern Qinling orogenic belt，which is a ductile shear zone-type gold deposit.Tectonic line of the area is generally distributed in the east-west direction.Hetaoyuan fault is the secondary fracture of the Shangdan fault and runs through the middle of the area.Based on the regional ductile shear zone，it evolved into brittle fracture.The fracture zone which is the boundary of the northern Lower Proterozoic and the southern Devonian stratums controls the distribution of stratums.There exist magmatic intrusive events in the area where structures are well developed and metallogenic conditions are advantageous.Through a comprehensive analysis for regional metallogenic background，geological features，geochemical characteristics，mineralization-alteration of Luoping gold deposit in Shangzhou，we predict the prospecting potential，and thus infer the area has good prospecting foreground.
