The archipelago group: current understanding
Bandopadhyay, P.C. and Carter, Andrew (2017) The archipelago group: current understanding. In: Bandopadhyay, P.C. and Carter, Andrew (eds.) The Andaman–Nicobar Accretionary Ridge: Geology, Tectonics and Hazards. Memoirs 47. Geological Society, London, pp. 153-166. ISBN 9781786202819.
Abstract
The geology and stratigraphy of the Archipelago Group are reviewed and new data presented to improve understanding. Major lithofacies are bioclastic limestones, bioturbated mottled marlstones, micritic limestones, trace fossil-bearing mudstones, quartzose sandstones and reworked volcanic material of Mio-Pliocene and Pleistocene age. The succession overlies the Pre-Neogene submarine fan turbidites and tectonic mélanges of ophiolite derivation and Mithakhari rocks, and is overlain by Quaternary deposits of late Pleistocene–Holocene age. The Neogene sequences were deposited in wave- and current-agitated shallow-marine intertidal and relatively deeper-water subtidal, nearshore and offshore shelfal environments. The existing stratigraphic framework is examined and suggestions made for improvement.
