摘　　要：粤北地区锡矿主要有石英脉带型锡矿、矽卡岩型锡矿、矽卡岩-破碎带复合型锡矿、脉状锡铅锌多金属矿、花岗岩风化壳型锡矿、云英岩型锡矿和砂锡矿等类型。根据区域成矿地质和物化探异常等特征,认为粤北地区石英脉型锡矿与矽卡岩-破碎带复合型锡矿具有良好的找矿前景,前者可作为今后该区域锡矿的主要找矿类型。根据区域成矿地质特征划分为5个找矿远景区,即锯板坑—瑶岭找矿远景区、杉木洞—禾尚田找矿远景区、大东山找矿远景区、岭脚找矿远景区、谢家山找矿远景区。There are many types of tin mine in northern Guangdong Province such as the quartz vein type,the skarn type,the skarnfracture zone composite type,the tin-lead-zinc polymetallic ore vein type,the granitoid weathering crust type,the greisen type and alluvial tin type. According to the regional ore-forming geological characteristics,geophysical and geochemical anomaly characteristics,it is found out that the tin mine of quartz vein type and skarn-fracture zone composite type have great prospecting potential,with the former as the key tin prospecting type in northern Guangdong Province. Based on the regional ore-forming geological characteristics,five prospective areas are indentified,namely,Jubankeng-Yaoling area,Shanmudong-Heshangtian area,Dadongshan area,Lingjiao area and Xiejiashan area.
