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 ...
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 ...
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 ...
Sedimentological responses to coastal dynamics along the Thane District, North Maharashtra, West Coast of India
(Springer, 2021)
We present the results of sedimentological responses to coastal dynamics of the Arnala beach, located between Vaitarna and Ulhas rivers, Thane district, Maharashtra, India. The coast is remarkably flat and wide and in the ...
Controls of mass transport deposit and magnetic mineral diagenesis on the sediment magnetic record from the Bay of Bengal
(Elsevier, 2021)
We conducted rock magnetic, mineralogical, sedimentological and geochemical analyses on a sediment core (MD161/Stn-11) retrieved from a complex marine sedimentary system of Krishna-Godavari (K-G) basin to delineate the ...
Diagenetic dissolution, maghemitization and sulphidization of magnetic minerals in rapidly deposited gas hydrate bearing sediments from the Bay of Bengal
(Elsevier, 2022)
We conducted a comprehensive rock magnetic investigation complemented by a scanning electron microscopy analyses on a 148.8 m sediment core (NGHP-01-20A) from the methane-hydrate bearing site in the Bay of Bengal to ...
Diagenetic analysis of shallow and deep-seated gas hydrate systems from the Bay of Bengal
(Elsevier, 2022)
This is the first systematic high-resolution rock magnetic study complemented by mineralogical and petrological observations conducted on sediment cores representing shallow (active cold seep; SSD-45/Stn-4/GC-01) and ...
Rock magnetic evidence of tectonic control on the sedimentation and diagenesis in the Andaman Sea over ~1 million years
(Elsevier, 2021)
We evaluate the sedimentary (magnetic, mineralogical, geochemical, grain size) records of a long sediment core (NGHP-01-17 A) to elucidate the tectonic control on the sedimentation and diagenesis in the Andaman Sea (AS) ...
Genesis and preservation of authigenic magnetite and greigite in the cold seep sediments, Bay of Bengal
(Elsevier, 2023)
We report a new mechanism of authigenic greigite and magnetite formation and preservation in an anomalous �sulfide-rich� interval in the cold (methane) seep sediments from the Bay of Bengal. Rock magnetic proxies (SIRM/?lf, ...
Sedimentary response to the contrasting provenance and oceanographic conditions on the continental shelf of India
(Elsevier, 2022)
The present study sets out to elucidate how magnetic minerals derived from wide array of source regions respond to shelfal sedimentary processes in a complex shelf system.Bulk sediment magnetic mineralogy comprised of ...
