Ferromanganese nodules and their associated sediments from the Central Indian Ocean Basin: Rare earth element geochemistry
(Taylor and Francis, 2001)
The rare earth element (REE) distribution in nine deep-sea ferromanganese nodules and their associated siliceous sediments from the Central Indian Ocean Basin (CIOB) have been studied to elucidate the REE relationship among ...
Lithological and mineralogical changes observed in a core from the western Bay of Bengal
(Allied, New Delhi (India), 1997)
Lithological and mineralogical studies were carried out on sediments from a 650 cm long core from the north western Bay of Bengal at a depth of 2700 m. These studies demarcate a boundary at 380 cm designated as unit 1 from ...
Origin and significance of high-grade phosphorite in a sediment core from the continental slope off Goa, India
(Current Science Association, Bangalore, India, 1995)
A phosphorite crust was found at 380-390 cm depth interval of a sediment core collected from the topographic high occurring on the continental slope off Goa. This crust is fragile and grey to light brown in colour. Carbonate ...
Rare-earth elements and uranium in phosphatic nodules from the continental margins of India
(Society for Sedimentary Geology (SEPM), Tulsa, USA, 2000)
A sediment core collected from a bathymetric high off Goa on the western continental margin of India has yielded phosphatic nodules at various subsurface depths (at 110, 150, 305 355, 435, 500, 505 and 525 cm). The nodules ...
Distribution of phosphorus and phosphatisation along the western continental margin of India
(Geological Society of India, 1987)
Phosphate content in the bulk sediments range from 0.02 to 2.17% and on carbonate free basis it varies from 0.03 to 6.5%. The partition studies indicate that contribution from the acid resistant detrital minerals (HCl ...
Geochemistry of zinc in the sediments of the western continental shelf and slope of India
(Indian Association for Limnology and Oceanography, 1985)
The bulk geochemistry of zinc in the sediments of the western continental shelf and slope of India and also the partition geochemistry of the sediments of the shelf and slope regions between Ratnagiri and Mangalore have ...
Geochemistry of Sediment cores of the Western Equatorial Indian Ocean
(Indian Association for Limnology and Oceanography, 1983)
Geochemical investigations including partition analysis have been carried out on nine sediment cores from the western equatorial Indian Ocean. The results show that a core from the Arabian Sea exhibits a greater terrigenous ...
Distribution of Al, Mn, Ni, Co & Cu in the Non-Lithogenous fractions of Sediments of the Northern Half of the Western Continental Shelf of India
(CSIR-NISCAIR, 1980)
Higher amounts of elements are associated with the nonlithogenous fractions of the fine grained terrigenous sediments of the innershelf region with low carbonate content than with the corresponding fractions of the coarse ...
Distribution of Fe, Mn, Ni, Co, Cu and Zn in Non-Lithogenous Fractions of Sediments of Gulf of Kutch
(CSIR-NISCAIR, 1980)
Contributions made by non-lithogenous fractions of sediments constitute a significant portion of the concentrations of the elements associated with the total sediment samples. The minor differences found in their distribution ...
Studies on the shelf sediments off the Madras coast
(National Institute of Sciences of India, 1968)
Sediment samples collected from the shelf and slope regions along two sections normal to the coast off Madras and Karaikal and from a few stations in between have been studied for their grain size, coarse fraction constituents ...
