摘要
在前人工作基础上,通过系统的野外观察,深入细致地对比研究发现,钨矿脉的"五层楼"模式在纵剖面上具正扇形结构,横剖面上具树形分叉结构,平面上沿构造带呈定向脉组(群)分布。矿区深部存在有两期隐伏花岗岩侵入活动,分别形成了两期石英脉型钨矿化,它们在空间上互相叠置,纵向上"五层楼"相互错位,构成"五层楼"叠加,这对矿区深部找矿具有重大指导意义。伴生组分查定发现,Ag含量>10-6的样品占57%,最高达2 584.7×10-6,普遍达到综合利用要求,可以提高矿山经济效益,为缓解矿山资源危机开辟新途径。
The ＂five-storey＂ model of the tungsten veins presents the straight fan structure on longitudinal sections, tree branch structure on cross sections, and directional veins group distribution along the tectonic beh on the plane in systematic field observation and detail study. There exist two periods granite intrusive activities in deep mines, forming two periods of tungsten mineralization with quartz vein. The ore veins, superposed each other in space, and mutual dislocated in the vertical sections, form a ＂five-storey＂ superposition model. Thus there is a great significance at deep exploration of the mine area. Recent discovery finds that the associated min-erals content of 57% of Ag is more than 10^-6, the highest is 2 584. 7 × 10^-6, within the multipurpose standard of application, which can improve the mine economic efficiency and open a new way for alleviating mine resources crisis.
