Eastern Myanmar is the key position linking between SW Yunnan and northern Thailand for better understanding of Tethyan evolution. However, the actual location and evolution of the Tethyan suture zone are still unclear in eastern Myanmar. The present study focuses on the geochronological, geochemical and zircon Lu-Hf isotopic study on the plutonic rocks, including granite, diorite and gabbroic rocks, from the Tachileik area, eastern Myanmar. These plutonic rocks yielded zircon U-Pb weighted mean ages of ca. 353–355 Ma, suggesting the Early Carboniferous emplacement. The Tachileik granites are high-K calc-alkaline, weakly peraluminous and have low P2O5 contents, which are typical features of Ⅰ-type granites. They have positive zircon
