基于数字矿床模型的陕西潼关县Q8号金矿脉西段三维成矿预测

陕西省潼关县桐峪金矿区Q8号矿脉是小秦岭为数不多的几个大型矿床之一.经过多年的开采和利用,目前该矿的地表矿和浅部矿已基本被采空,资源出现短缺,鉴于此,如何开展深部的三维矿产资源预测与评价成为当今技术研究的热点.将传统的二维找矿方法拓展到三维空间上,从三维角度实现金矿的深部地质定量化信息的可视化,运用三维空间的找矿标志变量进行深部隐伏矿体的三维预测,并根据预测结果的大小圈定了有利成矿区4处,从而为整个潼关地区的金矿资源开发提供科学依据,也为隐伏矿床的研究提供新的思路.

3D metallogenic prediction for western section of Q8 gold deposit in Tongguan County of Shaanxi based on digital mineral deposit model

Q8 gold deposit, located in Tongguan County of Shaanxi Province, was one of the few large deposits in Little Qinling Mountains. Through years of exploitation and utilization, the surface and the shallow resources for the mine were mined out. The shortage of resources made 3D prediction and evaluation for the deep mineral resources a hot spot concern in technical research. 3D space prospecting method was originated from 2D space and could realize visualization for the deep and quantitative geological information. Dominant variable of 3D space ore-prospecting could predict 3D structure of the deep concealed ore bodies. The authors pointed out four prospective gold mining areas according to the prediction probability. The studies provided scientific basis for the entire area of Tongguan gold resources, also provided new ideas for the research of concealed deposits.
