摘要
The study of Tethys, the southeast extension of the Tibetan Plateau, has aroused great interests among geologists all over the world. However, north-central Myanmar and its adjacent areas as the extension of Yunnan-Tibet Neo-Tethys in Southeast Asia have been very insufficiently studied. On the basis of the temporal-spatial distribution nature of the regional structure-rocks, the authors divided the study area into 7 third grade structural units, i.e., eastern edge of Indian continent, India-Burma range suture, west Myanmar continental block, Taguang-Myitkyina suture, Tengchong-Moulmein continental block, Luxi-Mogok suture and Baoshan-Shan Thai continental block. The three sutures were products of India-Burma range ocean, Taguang-Myitkyina ocean and Luxi-Mogok ocean, respectively.
