摘要
总结了都庞岭地区花岗岩和锡多金属矿床特征,提出蚀变花岗岩型是区内主要锡多金属矿床类型,矿床共同特征是主要矿体与蚀变岩体融为一体,矿床具有明显的垂直分带现象;花岗质岩浆的分异、熔离、自交代作用是该区锡多金属矿床成矿的主因。
On the basis of summarizing the geological feature of granites and tin poly-metallic deposits in Dupangling orefield,the author believed that altered granite type is the main type of tin-polymetallic deposits of the area, and the deposits show obvious vertical mineralization zoing. The authors concluded that differentiation, liquation and self-metasomatism of granitic magma are main factors for tin-polymetallic mineralization in the area.
