摘要
我国华北地区锡矿资源较为丰富,尤其是大兴安岭中南段,是我国三大主要锡成矿区之一,也是我国北方目前发现的唯一一个成型的锡多金属矿带。华北地区锡矿床类型主要分为热液型、斑岩型和接触交代型三类,多数为共生和伴生矿床,独立锡矿床较少。区内锡矿床成矿期主要集中于晚侏罗-早白垩世。本文分析了华北地区锡矿的主要控矿因素,初步建立了接触交代型、斑岩型和热液型锡矿床的成矿模式,探讨了锡矿的时空分布规律,提出锡林浩特-克什克腾旗、二连-东乌旗及商都-太仆寺旗地区为华北地区寻找锡矿的重点地区。
Tin resources are abundant in North China,especially in the middle and southern Greater Khingan Range,which is one of the three major tin mining areas in our country and the only formed tin polymetallic ore belt found in the north of China.The types of tin deposits in North China are mainly divided into three categories:hydrothermal,porphyry and contact account type,most of which are co-occurring and associated deposits,with few independent tin deposits.The mineralization period of tin deposits in the region is mainly concentrated in the Late Jurassic-Early Cretaceous.On this basis,the main ore-controlling factors of tin deposits in North China were analyzed,the metallogenic models of contact metasomatic,porphyry and hydrothermal tin deposits were initially established,and the temporal and spatial distribution of tin deposits were discussed,and Xilinhot-Keshiketeng Banner,Erlian-Dongwu Banner and Shangdu-Taipusi Banner are key areas for searching for tin deposits in North China.
