广东茶洞银金多金属矿区域上位于云开地区加里东褶皱隆起带之中,地处NE向吴川—四会大断裂北端与EW向贵子—挞石弧形断裂带的交汇部位。NE向吴川—四会大断裂带及断裂带内的次级断裂控制着区内的矿床分布,是区域上非常有利的构造成矿部位,成矿条件优越。笔者结合矿区勘查成果,简述了茶洞银多金属矿床地质特征,对矿床控矿因素及矿床成因进一步进行浅析,认为区域NE向吴川—四会大断裂、矿区内NE向和近SN向次级断裂构造是控制本区矿体形态、产状和规模的主要因素,为本区含矿溶液的活动和充填创造了良好的空间场所。
Located in the Caledonian fold uplift in Yunkai area, Guangdong Chadong silver gold polymetallic ore deposit is located at the intersection of the NE Wuchuan-Sihui large fault and the EW-Guizi-Tartar arc rupture zone. The NE-to-Wuchuan-Sihui large fault zone and the secondary faults in the fault zone control the distribution of the ore deposits in the area, which is a very favorable tectonic metallogenic site in the area with superior metallogenic conditions. Based on the results of mine exploration, the author briefly described the geological characteristics of the Chandong silver polymetallic deposit and further analyzed the ore-controlling factors and the genesis of the deposit. It is concluded that NE to Wuchuan-Sihui large fault, NE and near SN The secondary fault structure is the main factor that controls the shape, shape and size of the ore body in this area, which creates a good space for the activity and filling of ore-bearing solution in this area.
