江西省兴源冲铜矿区资源潜力评价

江西省兴源冲地区地处于九岭南缘多层次大型构造叠置成矿地质环境的西段,北东东向慈化—宜丰板缘深断裂带及大型推(滑)覆构造西段往南急速弧型大转折与湘赣边界北北东向走滑推覆冲断带复合部位,为形成多次成矿叠加、多类型聚合铜多金属矿床有利的异常构造、岩浆岩、矿源层及赋矿层、矿化异常等多种控矿因素耦合区,为区域1:20万和1:5万水系沉积物测量圈定的Cu,Pb,Zn高异常区。1:2.5,1:1万土壤地球化学测量已圈定出Cu,Pb,Zn,Au,Ag元素异常多处,综合异常4处,1:1万激电异常明显,具有明显的地、物、化、遥找矿信息。少量探槽、钻孔控制求得333+3341资源量已具小型规模,根据成矿地质条件及物、化异常综合分析本区深部铜矿资源潜力较大,有望达到中型以上规模。

Resource Potential Evaluation of Xingyuanchong Copper Deposit,Jiangxi Province

Xingyuanchong of Jiangxi Province is situated in the western metallogenic belt of multilayer superstructure of southern nine-ridges,where is a joint of NEE-trending Cihua-Yifeng fault,large-scale nappe(glide) structure and NNE-trending strike-nappe(glide) thrust between Hunan and Jiangxi province.It is also a coupling area with anomalous structures of multi-mineralization and variety of copper deposits,lots of ore-controlling factors such as magmatic rock,ore source and mineralization abnormal.This area has a high abnormal of Cu,Pb and Zn with stream sediment survey of 1:200 000 and 1:50 000.Several abnormal areas of Cu,Pb,Zn,Au and Ag,4 with comprehensive anomalies have been delineated with soil geochemistry mapping of 1:25 000 and 1:10 000.The 1:11 000 polarization anomalies are obvious.The ore deposit of No.333+3341 has been found with small reserve with several drillings.The deep copper resources are rich,even a middle-scale copper deposit.
