Behavior of rare earth elements in coexisting manganese macronodules, micronodules, and sediments from the central Indian Basin
(Taylor and Francis, 1994)Associated manganese macronodules, micronodules, and sediments from the Central Indian Basin (CIB) were analyzed for major, trace, and rare earth elements (REE) to understand REE carrier phases and their fractionation ... -
Benthic foraminifera from shelf region between Bombay - Ratnagiri: Distribution ecology and environmental significance
(Pune: Nowrosjee Wadia College, 1989) -
Benthic foraminiferal biocoenoses in the estuarine regimes of Goa
(Universita' degli Studi di Milano, 1984)Benthic Foraminifera are highly responsive to subtle changes in the estuarine environment. Keeping this in view, a qualitative analysis of living benthic Foraminifera was made of the samples collected from the Mandovi-Zuari ... -
Bolivina skagerrakensis, a new name for Bolivina cf. B. robusta with notes on its ecology and distribution
(Cushman Foundation for Foraminiferal Research, 1985) -
Bonanza from the frozen continent
(1983)Antarctica is a circumpolar continent surrounded by the Southern Ocean which is about 36 million sq kms and about 10% of the worlds oceans. Ice covers 98% of the continent and the rest is a non glacial terrain. Temperatures ... -
Boron in the modern deltaic sediments of the Krishna river and its offshore region, east coast of India
(Indian Association for Limnology and Oceanography, 1974) -
Ca++/Mg++ ratios in the sediments on the continental shelf off Bombay
(Indian Academy of Sciences, Bangalore, 1971) -
Calcareous nannofossils from sediments of the continental slope off Bombay (India)
(Universita' degli Studi di Milano, 1976) -
Carbonate mineralogy and faunal relationship in tropical shallow water marine sediments: Cape Comorin, India
(Elsevier, 1982)The carbonate mineralogy of Recent sediments from the western and eastern continental shelves around Cape Comorin off the southern tip of India was determined by X-ray diffraction analyses. The results show that in the ... -
Carbonate preservation during the 'mystery interval' in the northern Indian Ocean
(Terra Scientific Publishing Company, 2016)To understand carbonate dissolution and/or preservation on the sea floor since the Last Glacial Maximum (LGM), we measured shell weights of planktonic foraminifera Globigerinoides ruber from four sediment cores retrieved ... -
Cerium anomaly variations in ferromanganese nodules and crusts from the Indian Ocean
(Elsevier, 1994)Fifty analyses of rare earth elements as well as mineralogical studies have been carried out on a suite of manganese nodules and crusts from the Central Indian Basin and the Western Indian Ocean. The aim was to identify ... -
Characterization of 2004 Indian Ocean tsunami induced deposits along the Chennai coast using magnetic and geochemical techniques
(CSIR-NISCAIR, 2014)Present study is the applicability of rock magnetic techniques, coupled with geochemical (SiO<sub>2</sub>, Al<sub>2</sub> O<sub>3</sub> , Fe<sub>2</sub>O<sub>3</sub>, CaO, MgO, K<sub>2</sub>O, P<sub>2</sub>O<sub>5</sub>, ... -
Classification and inter-element relationships of ferromanganese nodules from the Central Indian Ocean Basin
(1987)The chemical composition of polymetallic nodule samples from 180 locations in the Central Indian Ocean Basin based on 600 chemical analyses has been investigated. These nodules contain a Mn/Fe ratio varying from 0.96 to ... -
Clastic dike from Baga, Goa
(Current Science Association, 1972)An uncommon feature of an occurrence of a clastic dike was noticed in Baga headland, Goa, India during the investigation carried out on the geological setting of Northern Goa Coast. Clastic dikes and related sills are ... -
Clay mineral distribution from Bhimunipatnam to Pudimadaka along cental eastern continental shelf of India
(CSIR-NISCAIR, 1989)Forty eight sediment samples, collected from 50-100m depth, have been analysed for their clay mineral composition and distribution. Kaolinite with chlorite (K + C) is the predominant mineral followed by illite and ... -
Clay mineral distribution in the shelf sediments off the northern part of the east coast of india
(Elsevier, 1988)Forty-eight sediment samples from the continental shelf between Visakhapatnam and the Ganges were analysed by X-ray diffraction for the composition and distribution of clay minerals. Estuarine samples of the Hooghly are ... -
Clay mineral distribution on the Kerala continental shelf and slope
(Geological Society of India, 1983)Seventy-five sediment samples collected from the Kerala continental shelf and slope during the 17th and 71st Cruises of @iRV gaveshani@@ were analysed by X-ray diffraction for clay mineral cntent. The distribution of total ...
