摘要
在野外调查和综合研究的基础上,将南岭中段主要锡矿床分为两类五型,即Ⅰ.岩浆期后气成-热液类锡矿床,Ⅱ.构造控制的多源热液类锡矿床;Ⅰ-1.变花岗岩型,Ⅰ-2.云英岩型,Ⅰ-3.矽卡岩型,Ⅰ-4.石英脉型,Ⅱ-1.构造蚀变岩型。初步建立了区内云英岩型、矽卡岩型和构造蚀变岩型锡矿的找矿模式,并就找矿中需要注意的问题以及主攻类型、找矿区位进行了讨论。
Based on field research and synthetic study, main tin deposits in the mid-Nanling region are divided into post-magmatic pneumatolytic hydrothermal type and polygenetic hydrothermal type controlled by structures,including five subtypes:alteration granite subtype, greisen subtype, skarn subtype, quartz vein subtype and structural alteration subtype. Primary prospecting model for greisen subtype, skarn subtype and structural alteration subtype have been put forwards. Besides, some problems related to main prospecting subtypes and areas are discussed.
