The mountains of western and northwestern Burma consist chiefly of colossal accumulations of Palaeocene to Eocene (Arakan and Chin Hills) or Senonian to Eocene (Naga Hills) Flysch of varying, including “exotic”, facies. The main frontal thrust zone of the Alpino-Himalayan Tectogene lies along and within the easternmost ranges of this Indoburman system, not along the western margin (Shan Scarp) of the Sinoburman Highlands. Some of the highest mountains in the Naga Hills are “Klippen” of metamorphics lying on Flysch. The Flysch ranges arose during the Oligocene but along the Arakan Coast there is ample evidence of an equally important earlier orogenic phase (latest Cretaceous) now almost totally buried beneath the western half of the Indoburman system and the post-Oligocene “Argille Scagliose” and “Macigno” on-lapping eastwards from the Bengal-Assam embayment. The lowlands of Central and Lower Burma do not represent a foreland feature, but an intramontane Molasse-filled basin to which the sea retained access because of a general southerly plunge of the Alpine Tectogene. Geotec-tonically, it is analogous to the Tibetan Plateau, not the Indo-Gangetic lowlands. |
