A rock magnetic perspective of gas hydrate occurrences in a high-energy depositional system in the Krishna-Godavari basin, Bay of Bengal
(Springer, 2020)
We conducted a detailed rock magnetic study complemented by sedimentological and mineralogical methods on a 177.2-m-long sediment core of Hole NGHP-01-14A to constrain the influence of high-energy depositional environment ...
Controls on greigite preservation in a gas hydrate system of the Krishna-Godavari basin, Bay of Bengal
(Springer Verlag, 2020)
Shallow sediments across large parts of Krishna-Godavari (K-G) basin offshore east central Indian contain abundant methane and gas hydrates. In this study, we carried out rock-magnetic and transmission electron microscope ...
Contrasting sulfidization in the turbidite and hemipelagic sediments of Bengal Fan
(Elsevier Ltd, 2020)
We report for the first time, contrasting sulfidization profiles in a sedimentary sequence comprising of clay-silt turbidites and hemipelagic dominated deposits in a channel-levee complex of the middle Bengal Fan. The ...
Widespread occurrence of methane seeps in deep-water regions of Krishna-Godavari basin, Bay of Bengal
(Elsevier Ltd, 2021)
Drilling/coring activities during NGHP-Expeditions 01 and 02 discovered significant gas hydrate deposits in the Krishna-Godavari (KG) basin, a proven petroliferous basin located along the eastern continental margin of ...
Strike-slip seismicity at the Andaman-Sumatra Subduction Zone: Role of the fracture zones and age of the subducting lithosphere
(Elsevier, 2021)
A better comprehension of the shallow strike-slip seismicity along the Sunda Trench is achieved by superimposing the Wharton basin fracture zones, magnetic isochrones, and focal mechanisms to the geometry of the subducting ...
Possible Linkages between Microseisms in the Andaman?Nicobar Region and Swells in the South Indian Ocean
(Seismological Society of America, 2021)
Microseism source characterization and its genesis play a key role in linking microseism records to prevailing atmospheric and oceanic conditions. In the present study, we analyzed the spatial and temporal distribution of ...
Magnetic Mineral Diagenesis in a Newly Discovered Active Cold Seep Site in the Bay of Bengal
(Frontiers Media SA, 2020)
Diagenetically formed magnetic minerals at marine methane seep sites are potential archive of past fluid flow and could provide important constraints on the evolution of past methane seepage dynamics and gas hydrate formation ...
Sub-surface magma movement inferred from low-frequency seismic events in the off-Nicobar region, Andaman Sea
(Nature Publishing Group, 2020)
Monitoring volcanic activity along the submarine volcanoes that are usually induced by subsurface magmatism is a challenge. We present fresh set of Ocean Bottom Seismometer (OBS) data that shows geophysical evidence ...
Diagenesis of Magnetic Minerals in Active/Relict Methane Seep: Constraints From Rock Magnetism and Mineralogical Records From Bay of Bengal
(Frontiers Media�, 2021)
In this study, we conducted a comprehensive investigation of rock magnetic, mineralogical, and sedimentological records of sediment cores supplemented by a high resolution seismic data to elucidate the controls of structural ...
Seismotectonic evaluation of off Nicobar earthquake swarms, Andaman Sea
(Elsevier, 2021)
The Andaman Sea has experienced a number of earthquake swarms as a result of complex tectonics arising from oblique subduction, active volcanic arc, the backarc spreading center, and sliver fault systems. One of the most ...
