锡矿处于滇西腾中—梁河锡矿集区南部,产于来利山复式花岗岩体中东外接触带,形成于岩浆期后气化—高温热液成矿阶段。晚期低温现出木锡石—锡石一蛋白石型矿床,严格受花岗岩及构造控制。
The tin deposit is located in the southern part of the Tengzhong-Lianghe tin deposit in the western Yunnan, and is produced in the outer contact zone of the Middle Lailiian complex granite, forming during the magmatic-hydrothermal hydrothermal mineralization stage. The late low temperature shows the kalinite-cassiterite-opal type deposit, strictly controlled by granite and structure.
