Control of source-to-sink processes on the dispersal, fractionation, and deposition of magnetic minerals in a tropical mesotidal estuarine system
Badesab, F.K.; Kadam, N.; Gullapalli, S.; Dewangan, P.; Gaikwad, V.; Satelkar, N.P.; Khalap, S.; Venkateshwarlu, M.; Sahoo, R.K.; Fernandes, Walsh; Dahake, P.; Banerjee, Deblina (John Wiley & Sons, Ltd, 2023)This study aims to elucidate the control of source-to-sink processes on the sediment dynamics of a complex mesotidal tropical estuarine system using rock magnetic, sedimentological, mineralogical, and geochemical methods. ... -
Controls of contrasting provenance and fractionation on the sediment magnetic records from the Bay of Bengal
Badesab, F.K.; Gaikwad, V.; Nath, B.N.; Venkateshwarlu, M.; Aiswarya, P.V.; Tyagi, A.; Salunke, K.; Fernandes, W.; Kadam, N.; Sangode, S.J.; Sardar, A.A.; Prabhu, G.A. (Elsevier, 2021)We present the results of rock magnetic, granulometric, microscopy and mineralogical analyses of shelf sediments off Krishna, Godavari, and Mahanadi Rivers, Bay of Bengal. The aim of the study was to assess the influence ... -
Diagenetic dissolution, maghemitization and sulphidization of magnetic minerals in rapidly deposited gas hydrate bearing sediments from the Bay of Bengal
Badesab, F.K.; Gaikwad, V.; Venkateshwarlu, M.; Kadam, N.; Joao, H.M. (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 ... -
Discovery of late Quaternary giant magnetofossils in the Bay of Bengal
Kadam, N.; Badesab, F.K.; Lascu, I.; Wagner, C.L.; Gaikwad, Virsen; Saha, A.; Sangode, S.; Venkateshwarlu, M. (Nature Publishing Group, 2024)Unusually large and enigmatic giant magnetofossils are well-documented in sediments deposited during and surrounding climatic events such as the Paleocene-Eocene Thermal Maximum (~56?Ma) and Middle Eocene Climatic Optimum ... -
Genesis and preservation of authigenic magnetite and greigite in the cold seep sediments, Bay of Bengal
Badesab, F.K.; Gaikwad, V.; Venkateshwarlu, M.; Kadam, N. (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
Kadam, N.; Badesab, F.K.; Gaikwad, V.; Kotha, M.; Fernandes, L.L.; Venkateshwarlu, M. (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 ...
