九江武山铜矿南矿带深部矿体特征分析——以-400 m标高以下8Cu矿体为例

Research on Characteristics of Wushan South Zone Copper Deposit in Jiujiang—— A Case of Study in the orebody of 8Cu below 400 meters

武山铜矿床是九瑞矿集区内著名的大型铜矿床之一,以该矿区区域地质特征与矿床地质特征为依据,结合深部详查钻探对矿区南矿带-400 m以下8Cu矿体形态、产状变化特征、矿石特征及其富集规律以及成矿有关的斑岩体形态特征的控制,进一步对8Cu矿体特征进行归纳与总结。随着与成矿紧密相关的碳酸盐岩地层的揭穿,表明8Cu矿体向深部延伸随碳酸盐岩地层控制尖灭而尖灭。通过深部与浅部相关成矿要素与预测要素的对比,结合矿区成矿预测模式与机理,积极寻找接替资源,建议进一步向矿区深部寻找斑岩型矿床,为本区找矿工作指明方向。

Wushan copper deposit is one of the large copper deposit in Jiujiang Ruichang ore famous area. Based on the Regional geological features and geological characteristics of the Wushan copper deposit. A combinatian of the Features of 8Cu orebody and orientation variations and ore characteristics and enrichment law and morphologi- cal characteristics of the porphyry related to mineralization drilling 400 meters below in South ore belt. By sum- ming up and summarizing the Features of 8Cu orebody further. With the exposed carbonate formation is closely re- lated to the mineralization. 8Cu showed that the orebody extends to depth with the carbonate strata pinchout and pinchout control. Through comparison of the deep and shallow metallogenic elements and related prognostic fac- tors. Combined with metallogenic prognosis model and mechanism. Actively looking for replacement resources. Further to the deep mining area for porphyry deposits. To specify the direction for the next step of prospecting work in this area .
