摘要
江西德兴铜皮坞矿区饰面花岗岩矿床位于扬子板块江南古岛弧南缘,九岭地体与怀玉地体拼接带(赣东北深大断裂[1])东侧,怀玉地体的西边。区域上大面积出露前寒武纪及早古生代地层,区域构造以北东向、北西向断裂为主,岩浆活动强烈,成矿地质条件良好。由于经历长期复杂的地质构造演化历史,发育多期区域性构造事件。不同时期、不同类型的构造形迹叠加在一起,形成复杂的区域构造格局[2]。综合区域地质背景、矿区地质特征、矿体特征及成矿时代,初步分析了铜皮坞矿区饰面花岗岩矿床的类型和矿床成因。
Jiangxi Dexing Tongpiwu＇s facing granite deposit mining area is located in the southern margin of the Yangtze plate Jiangnau ancient island arc, Jiuling body with Huaiyu body splice （deep fault that northeast of Jiangxi） on the east side, Huaiyu block in the west. Area on the large area exposed Precambrian Paleozoic strata as early as possible, east, north west and north of regional tectonic fracture is given priority to, magmatic activity is strong, and good ore-forming geological conditions. Because of the complicated geological tectonic evolution history, through long-term development phase of the regional tectonic events. In different periods, different types of structural feature added together, form a complicated tectonic pattern. Comprehensive regional geological background, geological characteristics, ore body characteristics and metallogenic epoch,ore body characteristics and metallogenic epoch, preliminarily analyzed just work facing granite deposit types and genesis.
