摘　　要：船岭脚锡矿为南岭锡多金属成矿带的一大型锡矿床。矿化类型较多,以构造蚀变带-矽卡岩复合型、接触带矽卡岩型锡矿为主,分布于中侏罗世姑婆山岩体接触带,且具分带性,自岩体内接触带往外依次为构造蚀变带-矽卡岩复合型、接触带矽卡岩型。矿化与成矿岩体及构造复合等因素密切相关,成矿物质主要来源于岩浆,为一与花岗岩有关的中高温矽卡岩型矿床。Chuanlingjiao tin-deposit in Hunan is a large one of the Nanling polymetal minerogenetic belt and there are many metallogenic types that are dominated by structural alteration-skam composite type and contact-skam type. The tin deposits distribute in contact zone of Guposhan granite body and show the characteristics of mineralization zoning which is the structural alteration-skam composite type and contact skam type zone from the granite body to outwards respectively. The tin mineralization closely related with mother granite body and structures, and major metallogenetic matters came from magma. We consider that the deposit belongs to a middle-high temperature skarn type deposit related with granite body.
