Ilmenite placer deposits in the bays of Jaigad, Ambwah and Varvada, Maharashtra, India
(Geological Survey and Mines Bureau, Dehiwala, Sri Lanka, 1997)
Growing demand for ilmenite owing to very limited resources of rutile and technological advancements in the industrial utilisation of ilmenite in place of rutile have excited interest in large-scale exploration for ilmenite ...
A new report on the occurrence of zeolitites in the abyssal depths of the Central Indian Basin
(Society for Sedimentary Geology, 1993)
Forty-two indurated slabs of zeolites collected from the abyssal depths of the Central Indian Basin have been studied. The slabs show characters similar to harmotome-rich scorias of the Society Ridge and phillipsite slabs ...
Evolution of the basalts from three back-arc basins of southwest Pacific
(Springer, 1999)
Petrography, petrochemistry, and mineral chemistry of basalts from the Woodlark, Manus, and Lau basins from the southwest Pacific have been studied to understand their magmatic evolution. Basalt from the western Woodlark ...
Geochemistry of calcareous sediments from the SW Carlsberg Ridge: Evidence for deeper carbonate compensation depth
(NISCAIR, CSIR, 1995)
Concentration of Mn, Fe, Ni, Co, Zn, Ca, Mg, K, Al, Si, Ti, P and CaCO sub(3) show wide range for the calcareous sediments from SW Carlsberg Ridge (CR). Compared with the average pelagic clays, the CR sediments are enriched ...
Deposition of Mn-Cu-Ni-enriched sediments during glacial period in the Central Indian Basin
(Current Science Association, Bangalore, India, 1993)
Two siliceous sediment cores collected from the Central Indian Basin have been analysed for organic carbon, biogenic silica, Al, Mn, Ni and Cu content. The concentrations of Mn, Cu and Ni showed one order of magnitude ...
Geochemical studies in the Godavari Estuary, India
(Elsevier, 1993)
The dissolved O sub(2), Fe, dissolved organic carbon (DOC), particulate organic carbon (POC), silica and U isotope measurements in reiver-estuarine waters of the Godavari and the concentrations of 23 elements in the suspended ...
Seasonal variation in an annually-banded coral Porites: A scanning electron microscopy investigation
(Elsevier, 1994)
Seasonal bands of the hard coral @iPorites@@ sp. collected from three different islands of Lakshadweep (Northwest Indian Ocean) are examined under a scanning electron microscope (SEM). SEM photographs reveal the presence ...
Geochemical trends in the sediments and manganese nodules from a part of the Central Indian Basin
(Geological Society of India, 1994)
Geochemical analyses of eighteen surface sediments samples collected from an area between 1 degree-15 degrees S latitudes and 73 degrees-87 degrees E longitudes exhibit significant variation in their chemical ...
Atypical ferromanganese micronodules from middle fan-valley system, Bay of Bengal
(Current Science Association, 1994)
Ferromanganese micronodules having botryoidal and spheroidal morphogroups have been observed over a 0.22 million km@u2@@ area from the middle fan region of the Bay of Bengal. The bulk micronodules have 26.26% Mn, 1.02% Fe, ...
Radiolarian abundance and geochemistry of the surface-sediments from the Central Indian Basin: Inferences to Antarctic bottom water current
(Current Science Association, 1994)
The distribution trend of numbers of radiolarian shells/gram dry sediment, biogenic silica, organic carbon, and the carbon/nitrogen ratios in the surface sediments of the Central Indian Basin is similar. Ratios of two ...
