| [摘 要]南秦岭柞山地区位于陕西省东南部,其西起柞水县,东到山阳县,面积约3000km2。其地处南秦岭海西-印支褶皱带东段,主体夹持于商丹缝合带与凤镇-山阳大断裂之间。作者总结了区域成矿地质背景,对热卤水喷流沉积型铜(银铅)矿、沉积-改造层控型铜矿、热液脉型铜(镍)矿、矽卡岩型铜(铁)矿、震裂岩型铜矿、斑岩型铜(钼、金)矿等6 种铜矿成矿类型的特征进行了探讨,在此基础上阐述了柞山地区铜矿的成矿规律,指出热水喷流型铜矿、斑岩型铜矿、沉积-改造层控型铜矿最具找矿潜力。目前已知的矿床(点)均受具导浆、导热、导流、导矿功能的区域性凤镇-山阳大断裂控制,并沿其两侧展布。未来一段时期,柞山地区铜矿找矿主攻类型为热水喷流型铜矿、斑岩型铜矿、沉积-改造层控型铜矿。找矿靶区首推柞水县银洞子矿床深部、山阳县池沟铜矿点、柞水县冷水沟铜矿点,次为柞水县张家坪铜矿点、山阳县色河铺铜矿点。通过进一步勘查有望取得铜矿找矿的重大突破。 |

| Abstract:The Zhashan area of the South Qinling Mountains lies in the southeast of Shaanxi Province. It begins from Zhashui County in west and terminates at Shanyang County in east, covering an area of about 3000 km2. It is located in the South Qinling Mountains Hercynian and Indosinian fold zone with the main body between the Shangdan suture zone and the Fengzheng-Shanyang fault. This paper summarizes the regional metallogenic geological setting, and studies the characteristics of the hot brine exhalogene type copper (silver lead ore), sedimentary reformation stratabound copper deposit, hydrothermal vein type copper (nickel) deposit, skarn copper (iron), hydrothermal cracking rock type copper deposits, and porphyry copper (molybdenum,gold) deposits in this area. Based on these data, we elaborate the copper metallogenic regularity in this area, and propose that hydrothermal exhalation type, porphyry copper deposit, sedimentary reformation stratabound copper mines show a great prospecting potential. Currently known deposits (orepoints) are all controlled by the regional Fengzheng-Shanyang fault which can conduct magma, heat, fluid and ore, and these deposits are distributed along both sides of the fault. The next exploration targets of copper deposits in the Zhashan area can be hydrothermal exhalation copper deposits, porphyry copper deposits and sedimentary reformation stratabound copper deposits. The preferred prospecting target areas are the deep part of the Yingdongzi deposit in Zhashui County, Chigou copper mining occurrence in Shanyang County, Lengshuigou copper mining occurrence in Zhashui County, followed by the Zhangjiaping copper mining occurrence and Sehepu copper mining occurrence in Shanyang County. Important exploration successes can be expected to find copper deposits through further surveys. |
