摘要
岑溪市鸭坑银矿位于桂东南铅锌金银多金属成矿带北东段,产于下奥陶统上段含砾砂岩、泥岩的蚀变断裂破碎带中。在分析研究矿床地质背景、构造特征、矿石矿物特征及围岩蚀变特征的基础上,指出该矿床属蚀变构造岩型独立银矿,找矿标志主要是断裂构造、地球化学异常、围岩蚀变、民采遗迹标志等,提出在佛子冲外围寻找该类型银矿的找矿模式。
Yakeng Silver deposit is located in the northeast part of Pb-Zn-Au-Ag polymetallic belt in South-eastern Guangxi,occurring in altered fracture zone and upper part of Lower ordovician gravel sandstone and mudstone.Based on the analysis of geological settings and tectonic characteristics,ore minerals and alteration of host rocks,this article points out that the deposit belongs to independant silver deposit of structural alteration type.Indicators for ore prospecting are mainly fault structures,geochemical anomalies,alteration of host rocks,and relics of old mining etc.It also provides prospecting model for searching the same type of silver deposit in the outskirt of Fuzicheng area.
