Continental collision boundary between Shanthai/Sibumasu blocks

Abstract

We report the petrological and geochronological analyzes results of metamorphic rocks from the Nujiang area (SW China), the Inthanon belt (W Thailand) and the Mogok belt (Myanmar), where related to Shanthai/Sibumasu cratons collision. Low-P/T metamorphic rocks are distributed in the every area. The collision related 200–210 Ma metamorphic event is assumed by Mnz EPMA age from the Nujiang area and the Inthanon area. In contrast, metamorphic rocks from the Mogok belt only received Indian continent collision event (< 50 Ma).
