Abstract
Four suture zones are probably present in Burma. Regional evidence indicates that the eastern Burma-Chiang Rai-medial Malaya suture resulted from closure of an oceanic basin, ocean I, in the early Triassic Projection from Tibet suggests that ocean II, north of the Lhasa block, closed in the end-Jurassic, but together with the Lhasa block itself, the suture is largely or entirely buried in Burma. The Mount Victoria Land block rifted from Gondwanaland in the Jurassic and collided with Burma, following northeastward subduction of ocean III, in the early Cretaceous. Triassic flysch and ophiolite overlying this block in western Burma correlate with the Triassic flysch and overlying Zangbo ophiolite in Tibet, suggesting that the Triassic flysch of Tibet was never adjacent to India. In the Eocene, before dextral displacement on the Sagaing Fault, India collided with northern Burma following subduction of ocean IV. This resulted in elevation of the Mogok Belt and Shan Plateau above a southeastward continuation of the Himalayan Main Central Thrust.
