摘　　要：广西全州县李家矿区锡矿发现8个锡矿体,呈脉状赋存于志留纪黑云母花岗岩与寒武纪清溪组侵入接触的内外接触带中的张扭性断裂带中,矿床成因类型为中温热液充填型脉状矿床,云英岩化、硅化、黄铁矿化等多种热液蚀变叠加是最重要的找矿标志。Eight tin ore bodies have been found in Lijia tin mine in Quanzhou County,Guangxi,which are vein shaped and occur in the tension torsion fault zone in the internal and external contact zone between Silurian biotite granite and Cambrian Qingxi formation.The genetic type of the deposit is mesothermal hydrothermal filling vein deposit,and the superposition of various hydrothermal alteration such as greisenization,silicification and pyritization is the most important prospecting sign.
