摘要
武功山变质岩区存在前震旦纪神山群上部火山—沉积建造和震旦纪下坊组硅铁建造二个含金矿源层,且区内经历多期次构造—岩浆事件,具备金的成矿条件。实地调研证实金的工业富集受断裂控制,故笔者认为区内找金应以破碎蚀变岩型金矿为目标,进而据前人资料和实地调研成果,在区内圈出大岗山—新坊等十个找金远景区。
Wugongshan metamophic area exists two gold- bearing source beds separatly in the volcano - sedimentary formation of the upper part of pre -Sinian shenshan Group and the silica iron formation of Sinian Xiafan Formation. This area had expericed multistage tectoni (- magma event and is possessed of ore forming Condition for gold. The industrial concentration of gold was controlled by fault. The author considers that in the area the prospecting for gold Should take the gold deposit of fragmented altered rock type for a target. Based on the predecessor information ard the stuocying result on the spot, the protential areds for gold exploring have been enclosed, such as DagangShan- Xinfang etc. in the area.
