摘要: 在对花岗岩几种重要的侵位机制进行介绍的基础上,结合野外工作实践,从围岩蚀变、流体运移、断裂控制等几个方面对云南个旧新山花岗岩体的侵位机制类型进行了综合分析,认为新山花岗岩体侵位机制类型属于岩浆底拱作用,新山矿段内形成的矿床主要有接触带铜锡多金属矿床、层脉状铜锡矽卡岩硫化矿床、变质火山岩铜矿床。

Abstract: Several important emplacement mechanisms are described.Based on this, a comprehensive analysis on emplacement mechanism types of Xinshan granite in Yunnan Gejiu is carried out from aspects of wall rock alteration, fluid movement, and fracture control, combining with the field work and practice.The paper holds that the emplacement mechanism types of Xinshan granite belong to Magma arch effect, and the deposits which are formed in Xinshan ore section are mainly the contact zone copper and tin polymetallic deposit, the vein copper and tin skarn sulfide deposit, and the metavolcanite copper deposit.

Key words: Granite, Emplacement mechanism, Wall rock alteration, Xinshan granite body
