Geochemistry of the Neoarchean Dodguni carbonates of Chitradurga greenstone belt, Dharwar Craton, India: Implications on depositional environment
Khelen, A.C.; Manikyamba, C.; Subramanyam, K.S.V.; Raza, Waseem; Reddy, H.G. (Wiley, 2023)The carbonates of the Dodguni area of the Chitradurga greenstone belt, Dharwar Craton, India were studied to understand the Archean diagenetic and palaeo-depositional conditions using carbon and oxygen isotopes along with ... -
U enrichment and Th/U fractionation in Archean boninites: Implications for paleo-ocean oxygenation and U cycling at juvenile subduction zones
Manikyamba, C.; Said, N.; Santosh, M.; Saha, A.; Ganguly, S.; Subramanyam, K.S.V. (Pergamon, 2018)Phanerozoic boninites record enrichments of U over Th, giving Th/U: 0.5-1.6, relative to intraoceanic island arc tholeiites (IAT) where Th/U averages 2.6. Uranium enrichment is attributed to incorporation of shallow, ... -
Yttrium and rare earth element contents in seamount cobalt crusts in the Indian Ocean
Balaram, V.; Banakar, V.K.; Subramanyam, K.S.V.; Roy, P.; Satyanarayan, M.; RamMohan, M.; Sawant, S.S. (Current Science Association, 2012)Cobalt-rich Fe-Mn crusts occur on almost all seamounts and plateaus of the world oceans. Fe-Mn crusts are formed through layer-by-layer accretion of colloidal precipitates from cold ambient seawater onto exposed seamount ...
