| 中文摘要: |
| 随着双王金矿床的不断开采，矿山探明的资源储量已消耗殆尽，企业面临着严重的资源危机，接替资源的探矿工作迫在眉睫。为解决制约矿山找矿突破的关键问题，通过对双王金矿床角砾岩带外围开展系统的地质调查研究，在角砾岩带(下盘)南部发现了新类型微细浸染型 KT8-1金矿体，核实已控制的金矿体资源量 2.4 t，实现了双王金矿床找矿的重大突破。发现的新类型矿体严格受构造控制，尤其以 NW-NWW构造脆韧性剪切带、复式褶皱构造为主要控矿因素，矿(化)体均赋存于石英脉及石英脉与围岩接触带上。为了扩大矿体的规模，对 KT8-1矿体外围、深部开展了构造叠加晕及高密度电法研究，圈定了找矿靶区 2处，其中 1处找矿靶区经工程验证探获了工业矿体。结合区域地质资料认为，矿区新类型矿体成矿地质背景良好、已有找矿成果显著，具有寻找更多隐伏金矿体的潜力。 |

| With the continuous exploitation of the Shuangwang gold deposit, the proven resource reserves ofthe mine have been exhausted, and the enterprise is facing a serious resource crisis. The exploration work to replacethe resources is imminent. In order to solve the key problems that restrict the breakthrough of mine prospecting, asystematic geological survey was carried out on the periphery of the breccia belt of the Shuangwang gold deposit. Anew type of micro-disseminated KT8-1 gold ore body was found in the south of the breccia belt (footwall), and thecontrolled gold ore body resource was verified to be 2.4 tons, which achieved a major breakthrough in the prospect.ing of the Shuangwang gold deposit. The new type of ore bodies discovered by are strictly controlled by structures,especially the NW-NWW brittle-ductile shear zone and composite fold structure are the main ore-controlling fac.tors. The ore (mineralized) bodies are all hosted in quartz veins and the contact zone between quartz veins and sur.rounding rocks. In order to expand the scale of the ore body, the structural superimposed halo and high-densityelectrical method were carried out on the periphery and deep part of the KT8-1 ore body, and two prospecting targetareas were delineated. One of the prospecting target areas was verified by engineering to find industrial ore bodies.Combined with regional geological data, it is believed that the new type of ore body in the mining area has a goodmetallogenic geological background and significant prospecting results, and has the potential to find more concealedgold ore bodies. |
