摘　　要：本文在野外地质调查基础上,结合前人研究资料及部分项目研究成果,在分析研究腾冲-毛淡棉构造带的成矿地质背景、构造岩浆演化和主要钨锡矿床成因类型的基础上,探讨了构造岩浆演化与钨锡成矿系统的形成关系和花岗岩成矿作用。选取构造岩浆带内来利山和赫敏之两个典型岩浆热液型锡钨矿床,进行矿床特征、矿床成因、成矿成岩时代及构造背景的对比研究发现,腾冲-毛淡棉构造岩浆岩带可能具有统一的构造-岩浆-成矿演化系统,为一个燕山-喜山期形成的构造-岩浆-成矿带。这一认识对于指导该地区锡钨矿成矿预测和地质找矿工作具有重要意义。This paper explores the metallogenie background,tectonic evolution and nmin genetic types of the W-Sn deposits in the Tengchong-Moul- mein tectono-magmatie-metallogenie belt and discusses its tectono-magmatie evolution,tin-tungsten ore forming system and the mineralization of granitoid rocks based on the field investigations, previous work and part of the project study achievements. We select the Lailishan and Hermyingyi magmatic hydro- thermal Tin-Tungsten ore deposits to do comparative studies about their deposit characteristics, ore genesis, metallogenic epoch and tectonic setting. The re- sults show that the Tengehong-Moulmein tectonic magmatic belt may form in a unified tectono-magmatic-metallogenie evolutive system, and is a huge Yans- hanian-Himalayan teetono-magmatie-metallogenie belt. This recognition is of great significance for tin-tungsten metallogenic prediction and geological ex- ploration in the area.
