赣北大湖塘钨铜多金属矿集区特征与成矿作用模式
Characteristics and Mineralization Model of the Dahutang Tungsten-Copper-Polymetallic Ore Concentration Area in Northern Jiangxi Province
摘要
Abstract
Objectives:The Dahutang tungsten—copper—polymetallic ore concentration area is located on the north side of the central Qinzhou—Hangzhou (Qin-Hang ) composite orogen,southeastern margin of Yangtze plate.Most exposed bedrocks in the area are the Jinning Period (Neoproterozoic)biotite granodiorite(mainbody of the Jiuling batholith),a few are low metamorphic fine elastic rocks of the Neoproterozoic Shuangqiaoshan Group(residual cap of the Jiuling Batholith),porphyritic granite,fine grained granite and granite porphyry of Yanshanian period. <br> Methods:Based on the research results of comprehensive regional geological structure,this paper uses the principle of structural analysis to analyze the Yanshanian tectono—magma—mineralization in Dahutang Mining Area. <br> Results:It is concluded that the super large tungsten—copper polymetallic ore-forming in this area is closely associated with the occurrence, development and evolution of Yanshanian tectonic- magmatic hydrothermal mineralization system,among which metallogenic structure and metallogenic structural surface are the basises of mineralization,and the metallogenetic rock body is the key to mineralization. <br> Conclusions:Mineralization is the coupling results of metallogenic structure,metallogenic structural surface and metallogenetic rock body.关键词
