Burman Tertiary Basin

Burman Tertiary Basin major Tertiary (66 million years to 2 million years ago) Basin of Burma, also known as Central Burman Basin. It is located in the middle part of Burma (Myanmar), between 16'N to 25'N latitude and 94'E to 97'E longitude. The basin runs approximately 1,100 km across the central part of the country and includes low-lying region between the Sino-Burman Highland and Indo-Burman Ranges. The north-south trending Tertiary volcanic rocks of volcanic arc complex separates Central Burma Basin into an elongated, fore-arc basin to the west and back-arc basin to the east. The fore-arc basin contains a thick more than 9,144m section of Tertiary to Recent age (ie 66 million years to present) sediments, resting upon an unknown thickness of older sediments. The back-arc basin of the Central Burman Basin is a Middle Tertiary and younger feature and contains largely Miocene (24 to 5 million years ago) and younger lacustrine and fluvial deposits. The volcanic arc of the Central Burman Basin contains evidence of Late Mesozoic to Pleistocene (around 144 million years to 0.1 million years ago) eastward subduction of the Indian Ocean plate beneath the Burmese plate.
