Morphotectonic characteristics of the Andaman volcanic arc and …
2024年8月1日 · This study presents an examination of the morphotectonic features of the Andaman Backarc region, with a special emphasis on the inner volcanic arc, sliver fault system, and small oceanic basins in the Andaman backarc region.
Andaman Nicobar | NDR (National Data Repository)-Directorate …
The Andaman-Nicobar basin represents a typical Island arc system. The basin came into existence as a result of the northward movement and anticlockwise rotation of the Island Plate and its under thrusting under the Asian plate in the Cretaceous time.

2005年4月1日 · From the west end of the Central Andaman Basin rift to its northern end, it may have been primarily a reverse fault forming the Invisible Bank Cuesta and uplifting older forearc basin sediments, while from this point south it also served as a strike-slip transform fault to northwest Sumatra.
Tectonics of the Andaman Backarc Basin—Present ... - Springer
2020年2月29日 · The Andaman Sea in the northeast Indian Ocean is an active marginal basin consisting of trench-arc-backarc elements. The extension in the Andaman Sea is primarily driven by oblique subduction of the Indian-Australian plate beneath the Southeast Asian/Sunda plate.
Chapter 13 Anatomy of the Andaman–Nicobar subduction system …
In the following sections, we summarize our findings and characterize the major features of the Andaman–Nicobar system from west to east, starting from the nature and role of the subducting plate, the forearc system, the sliver plate boundary and the back-arc Andaman Sea.
New insights into the tectonic evolution of the Andaman basin ...
2004年4月30日 · The Indo-Burmese range and the Andaman arc system in the northeast Indian Ocean define a zone of underthrusting of the Indian plate below the Southeast Asian plate, leading to the formation of a major island arc–trench system.
Andaman Island Arc and Back-Arc Sea | SpringerLink
2015年11月27日 · The Andaman Sea is thus a back-arc basin formed as the seafloor spread after splitting apart along the NNE–SSW trending rift. Oblique convergence entailed rotation of oceanic subplates and increased rate of strike-slip motion. The …
Three-phase tectonic evolution of the Andaman backarc basin
A three-phase evolutionary scheme since Late Oligocene for the Andaman backarc basin is proposed based on the multibeam swath bathymetry, magnetic and seismological data. A SW–NE trending spreading ridge bisects the basin.
Back‐arc extension in the Andaman Sea: Tectonic and magmatic …
2013年4月24日 · The boundary between the sliver, Burma Plate, and the Sunda Plate is a system of arc-parallel transforms and arc-normal ridges in the back-arc of the Andaman Sea, which connects to the right-lateral Sumatra fault along the volcanic arc in the southwest (Figure 1).
Sequence stratigraphy of the Andaman Basin, northern Indian Ocean
2021年11月1日 · The Andaman Basin forms a part of large geotectonic unit “the great Indonesian Island Arc system”. The Andaman Island Arc system is associated with convergence of Indo- China Plate (West Burmese plate) and subducting eastern Indian Oceanic plate.
