摘要
This paper explores the metallogenic background,tectonic evolution and main genetic types of the W-Sn deposits in the Tengchong-Moulmein tectono-magmatic-metallogenic belt and discusses its tectono-magmatic 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 hydrothermal Tin-Tungsten ore deposits to do comparative studies about their deposit characteristics,ore genesis,metallogenic epoch and tectonic setting. The results show that the Tengchong-Moulmein tectonic magmatic belt may form in a unified tectono-magmatic-metallogenic evolutive system,and is a huge Yanshanian-Himalayan tectono-magmatic-metallogenic belt. This recognition is of great significance for tin-tungsten metallogenic prediction and geological exploration in the area.
