摘要
This paper combined the predecessors’ research of emplacement mechanism of granite, discussed several important emplacement mechanisms in details. On the basis of this, with field work and practice, the author carried out a comprehensive analysis from the wall rock alteration, fluid movement, and fracture control in emplacement mechanism types of Xinshan granite in Gejiu, Yunnan Province. The author holds that the emplacement mechanism types of Xinshan granite belong to Magma arch effect, and the deposits which in Xinshan ore section mainly has the contact zone copper and tin polymetallic deposit, the vein copper and tin skarn sulfide deposit, the metavolcanite copper deposit.
