| 摘 要： | 广东梅子窝钨矿是我国石英脉型钨矿"五层楼"矿化模型理论形成的发源地。近年来，钻探和矿山生产揭露显示钨矿脉已向下延伸到花岗岩体内部二、三百米仍然没有尖灭，与传统的"五层楼"矿化模型存在出入。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，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。 |

| Abstract: | Meiziwo tungsten deposit,located in Guangdong province,is a cradle for establishment of the model of "Five-storyed" quartz veins in China.Drilling in recent years revealed that tungsten ore vein does not disappeare after extending two to three kilometers inside granite,which is discrepancy with the conventional model of "Five-storied" quartz veins.Based on previous work and systematic observation in the field,along with comparison study,two hidden granite intrusive events have been identified in the deep part of the Meiziwo tungsten deposit and correspond to two quartz vein type tungsten mineralization events respectively.Spatically,these veins are vertically superimposed,forming a "Five-storied" superimposed model,which is of great significance at deep exploration of mine area. |
| Keywords: | Meiziwo tungsten deposit quartz vein overprint model of five layers |
