Surficial Sediments of the Continental Shelf off Karnataka
(Geological Society of India, 1981)
The continental shelf in this area is about 80 km wide and the edge of the shelf varies between 90 and 120 m water depth. Geologically modern fine-grained clastic sediments occur between the water depth. Geologically modern ...
Studies on the Sediments of Vembanad Lake, Kerala State. 4. Distribution of Trace Elements
(CSIR-NISCAIR, 1981)
Distribution patterns of FE, Mn, Ti, Ni, Co and Cu in sediments of Vembanad Lake and adjoining river systems have revealed that (1) elemental concentrations follow closely the texture of the sediments, (2) river sands ...
Distribution of Strontium in Sediments of the Minicoy Atoll, Lakshadweep
(CSIR-NISCAIR, 1980)
Sr content in 67 sediment samples collected from the Minicoy reef and lagoon varies from 3960 to 7000 ppm (av. 5630 ppm). The concentration increases from the reef (c 4,000 ppm) in the north and west to the centre of the ...
Relationship between Benthic Foraminifera and Sediment in the Estuarine Complex of Goa
(Indian Association for Limnology and Oceanography, 1980)
Two indices of community association were used to elucidate the relationship between changes in species composition of benthic foraminifera and changes in the grain size composition of the sediment in estuarine complex of ...
Sandwaves of the Gulf of Khambhat
(CSIR-NISCAIR, 1980)
In the Gulf of Khambhat (Gujarat, India) the best formed sandwaves are seen in the west close to the Eastern Sand Bank. With increasing clay content and clay cover of the sea bed, the sandwaves become poorly formed. In the ...
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 ...
Foraminiferal Constituent in Marine Sediments - A Parameter in some Coastal Engineering Problems
(Indian Association for Limnology and Oceanography, 1980)
Foraminifera, among other microorganisms, form a major constituent of marine sediments and their composition is directly related to the nature of the substrate in which they are entombed. Past and the present data indicate ...
Mineralogy of polymetallic nodules and associated sediments from the Central Indian Ocean Basin
(Elsevier, 1987)
Todorokite is the dominant mineral phase in the nodules of the northern Central Indian Ocean Basin. These nodules are characterised by a rough surface texture, are relatively rich in Mn, Cu and Ni, and are associated with ...
