Rare earth element studies of surficial sediments from the southwestern Carlsberg Ridge, Indian Ocean
(Indian Academy of Sciences, Bangalore, India, 1995)
The rare earth element (REE) contents of sixteen surficial calcareous sediments from the southwestern Carlsberg Ridge, Indian Ocean, have been determined. The total REE vary from 35 ppm to 126 ppm and are inversely related ...
Evidence for recent hydrothermal activity in the Central Indian Basin
(Pergamon, 1997)
This study documents the first actual prof of recent intraplate volcanic-hydrothermal activity in the Central Indian Basin (CIB). Twenty-six surface sediments and a spade core (37 cm long) from the CIB were examined for ...
Sedimentological and clay mineral studies in Kakinada Bay, east coast of India
(NISCAIR, CSIR, 1996)
The sediments of Kakinada Bay are predominantly silty clays, with a phi mean range between 2.9 to 7.8 northern, central and southern parts of the bay consist of finer sediments (5.5 to 7.05 phi) while the eastern and western ...
Palaeoceanographic conditions during the formation of ferromanganese crust from the Afanasiy Nikitin seamount, north central Indian Ocean: geochemical evidence
(Elsevier, 1997)
A ferromanganese crust dredged from the summit of the Afanasiy-Nikitin seamount in the composed of fresh-water phreatic calcite cement, Terebratulinae casts, rounded and ferruginised basalt clasts and weathered coralline ...
Trace elements in near-shore sediments along the east and west coasts of India
(Science and Technology Agency of Japan (JISTEC, STA), Japan, 1999)
To understand the distribution of trace elements and their controlling factors in the coastal regions of India. Some representative sediment samples from the nearshore regions were selected from the east and west coasts ...
Models for changes in atmospheric carbon dioxide, ocean geochemistry and circulation during the late Pleistocene
(Vikas Publication, 1990)
This report provides a review of various hypotheses put forward so far as to the role of the oceans in controlling the glacial-interglacial climatic cycles through controls on the atmospheric carbon dioxide. The available ...
Rare earth element distribution and behaviour in buried manganese nodules from the Central Indian Basin
(Elsevier, 1993)
Eight burried manganese nodules taken in the upper metre of a siliceous ooze sediment core in the Central Indian Basin at 14 degrees S and 74 degrees E were analysed for major, trace and rare earth (REE) elements. ...
Geochemistry of deep-sea sediment cores from the Central Indian Ocean Basin
(NISCAIR, New Delhi, 1993)
Four sediment cores from the Central Indian Ocean Basin (CIOB) were studied to characterise the coarse fraction (less than 63 mu), transition metal and major oxide contents. Transition metals (Mn, Cu, Ni, Zn) show enrichment ...
Controls on organic carbon distribution in sediments from the eastern Arabian Sea margin
(Springer, 1997)
Sediment cores from the upper continental slope of the eastern Arabian Sea have high organic carbon (OC), CaCO sub(3), and sand content at the top. The values decrease with increasing depth in the Holocene and Upper ...
Dune associated calcretes, Rhizoliths and Paleosols from the western continental shelf of India
(Geological Society of India, 1997)
The calcareous deposits on the western continental shelf of India, off Bhatkal (water depths 50 to 58 m) occur as crusts, sheets, cylinders and reddish brown mudstones. The outer layers of the crusts are micrite-dominated ...
