摘要
从区域地质、矿区地质、矿体地质、岩石地球化学等方面对狮尾洞及周边的典型矿床进行稀土分布模式、微量元素蛛网图、矿物岩石及化学成分等综合研究。结果表明,矿化类型主要有两种:含钨石英脉、含钨花岗岩;与成矿有关的岩体为燕山期斑状白云母花岗岩,成因类型为S型花岗岩;蚀变主要有云英岩化、黑云母化、硅化、钾长石化等;控矿构造为大湖塘-同安北北东向大断裂,该断裂控制了区内燕山期岩浆岩带和矿化带的展布;晋宁期花岗闪长岩是主要的成矿围岩,是间接的矿源层。
Previous research data on the Shiweidong deposit and its peripheral tungsten deposits were collected comprehensively,including regional geology,mine geology,ore body geology,rock geochemistry,etc.Comprehensive studies on REE distribution pattern,trace elements,mineral and whole-rock geochemical composition of Shiweidong deposit and its surrounding deposits show that:There are two types of mineralization:tungsten-bearing quartz vein type and tungsten-bearing granite type.The granite related to mineralization is the Yanshanian porphyritic white mica granite,which is S-type granite;Alteration types are mainly include miconization,biotite mica,silicification,potassium albitization,etc.Ore-controlling tectonics are the great NNE fault of Dahutang-Tong’an,which controlled the distribution of magmatic belt and mineralization belt in Yanshanian period.Ore-forming surrounding rock is the granite diorite in the Jinning period,which is the indirect source rock.
