Authigenic carbonates in the sediments of Goa offshore basin, western continental margin of India
(Current Science Association, 2012)Euhedral crystals (approx. 1 mm) of authigenic carbonates are identified in 5 m long sediment cores collected from the western continental margin of India in water depths between 2665 and 3070 m. Low-Mg calcite and aragonite ... -
Carbonate and carbon fluctuations in the Eastern Arabian Sea over 140 ka: Implications on productivity changes?
(Elsevier, 2005)Biological productivity in the western Arabian Sea was higher during interglacial than glacial times. In the eastern Arabian Sea productivity was higher during the glacials compared to interglacials, which is in sharp ... -
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 ... -
Microbial dolomite crusts from the carbonate platform off western India
(International Association of Sedimentologists, 2003)The occurrence of Late Pleistocene dolomite crusts that occur at 64 m depth on the carbonate platform off western India is documented. Dolomite is the most predominant mineral in the crusts. In thin section, the crust ... -
Mineralogy of the carbonate sediments - western continental shelf of India
(Elsevier, 1981)An X-ray diffraction study of forty-six sediment samples and three oolitic limestone samples from the western continental shelf of India shows that aragonite is the dominant carbonate mineral (99% maximum), followed by ... -
Ooid turbidites from the Central Western continental margin of India
(Springer, 1989)Gravity displaced debris flows/turbidites have been observed in five box cores collected between water depths of 649 and 3,627 m from the Central Western continental margin of India. Studies on grain size, carbonate content, ... -
Particle flux during the southwest monsoon on the western margin of India
(University of Hamburg, 1987)Three sediment traps on a mooring were deployed on the outer shelf at a depth of 115 m from May to September 1985 on the western continental margin of India to study the particle flux during the southwest monsoon The ... -
Record of carbonate preservation and the Mid-Brunhes climatic shift from a seamount top with low sedimentation rates in the Central Indian Basin
(John Wiley, 2013)In the present investigation, an age model of carbonate-rich cores from a seamount top in the Central Indian Basin (CIB) was constructed using both isotopic (sup(230)Th sub(excess), AMS sup(14)C, oxygen isotopes) and ... -
Significance of relic carbonate deposits along the central and southwestern margin of India for late Quaternary environmental and sea level changes
(Elsevier, 2003)Environmental and sea level indicators were investigated using dredge samples from late Quaternary carbonate deposits along the shelf break between Goa and Cape Comorin, India. Geomorphic features in the area were identified ... -
Size distribution and carbonate content of the sediments of the western shelf of India
(National Institute of Sciences of India, 1968)Sediment samples collected during the 25th cruise of I.N.S. KISTNA (Indian Programme of I.I.O.E.) were analysed for grain size and carbonate content. The shelf sediments show well defined zonation, except where river-borne ...
