胶东地区是我国重要的黄金产地之一,具有得天独厚的成矿环境。玲珑式金矿是指发育在中生代花岗岩中的构造剪切带含金黄铁矿石英脉—黄铁绢英质碎裂热液蚀变岩型金矿床,该类花岗岩交代重熔的基体是前寒武纪含中—基性火山岩的沉积变质岩系,以玲珑金矿西山宽大石英脉金矿为代表。通过分析玲珑断裂带地质及地球物理特征,以及在该区开展激电中梯剖面测量和激电中梯测量等工作,成功推断反演出矿致异常,采用钻探手段进行了异常验证,取得了很大的找矿突破,这将为玲珑断裂带今后找矿工作提供理论依据。
Jiaodong region is one of China’s major gold producing areas, has a unique mineralizing environment. Delicate gold is developed in the Mesozoic granitic tectonic shear zone containing golden iron ore vein - yellow iron seric fission hydrothermal alteration rock type gold deposit, the type of granite replacement remelted matrix is the Precambrian Sedimentary metamorphic rocks containing medium-basic volcanic rocks are represented by the Lingshan gold deposit, Xishan generous quartz vein. By analyzing the geologic and geophysical characteristics of the exquisite fault zone, and conducting the survey of the mid-lift profile and the mid-lift measurement in this area, the ore-induced anomaly was successfully inversed and the anomaly was verified by drilling. Large breakthrough in prospecting, which will provide the theoretical basis for prospecting for the exquisite fault zone in the future.
