Abstract
This paper focuses on the Dongyang quartz vein type tungsten deposit located in the middle section of the Fengxian Zhen'an fold belt in the southern Qinling Indosinian fold belt of the Qinling fold system.The magmatic rocks in the area are developed,and the Jiangkou rock mass and the Laziandeng rock mass are characterized by multiple stage complex rock masses.The Laziandeng rock mass is the metallogenic rock mass in the area,which is a quasi aluminum weak peraluminous crust source S-type granite,and the ore minerals are scheelite,pyrite,chalcopyrite,and molybdenite,Gangue minerals include quartz,calcite,sericite,etc.Based on the analysis and study of the structural characteristics,rock mass properties,and ore body characteristics in the area,it is believed that the ore-forming geological conditions of the deposit are good,and the prospecting potential in the deep and peripheral areas of the deposit is large.关键词
