Clay mineral distribution on tropical shelf: an example from the western shelf of India
(Indian Association of Sedimentology, 1989)
Seventy-five sediment samples collected from the Kerala continental shelf and slope during the 17th and 71st Cruises of RV Gaveshani were analysed by X-ray diffraction for clay mineral content. The distribution of total ...
Morphology and evolution of the central west coast of India
(Indian Association for Limnology and Oceanography, 1989)
Size, surface texture, chemical composition and mineralogy interrelations in ferromanganese nodules of central Indian Ocean
(CSIR-NISCAIR, 1989)
Fiftyseven ferromanganese nodules, classified into 3 size class (4,4-6 and 6-8 cm diam.), from the siliceous sediments of central Indian Ocean were analysed for transition metals and representative sample from each size ...
Variability of Mn, Fe, Ni, Cu and Co in manganese nodules from the Central Indian Ocean Basin
(Elsevier, 1989)
The trace element variations in manganese nodules from the Central Indian Basin have been related to the underlying sediment type. Percentages of Mn, Cu and Ni are high in nodules occurring in siliceous sediments compared ...
Analysis of magnetic anomalies in relation to Placer deposits and basement configuration off Mirya bay, Central West coast of India
(1988)
The offshore ilmenite placers off Konkan, central west coast of India, have been surveyed by echosounding, shallow seismic profiling, magnetics, and seabed sampling. The magnetic data show two different types of anomalies: ...
Ferro-manganese oxide growth on shark teeth from cenral Indian Ocean basin
(CSIR-NISCAIR, 1988)
Study of ferro-manganese oxide growth on apatitic substrates like shark teeth enamel from siliceous sediment environment (lat. 10 degrees S and long. 75 degrees E) suggests the changes in depositional environments within ...
Texture, carbonate content and component composition of Mauritius beach sands, Indian Ocean
(Tirunelveli: JCSONLINE, 1988)
Samples collected from beaches bordering the southern, southeastern, western and northwestern shores representing swell (windward) and non-swell (leeward) dominated environments of the island of Mauritius were studied in ...
Geoscientific investigations on the Indian coast: Their application to interpret the paleoclimates and future sea level changes with special reference to greenhouse effect
(1988)
Objectives of this paper are: (1) To delineate the paleo sea level fluctuations and erosional environmental changes along the Indian Coast and their relationship with the changing coastline and human settlements in the ...
Nature, distribution and origin of clay minerals in grain size fractions of sediments from manganese nodule field, Central Indian Ocean Basin
(CSIR-NISCAIR, 1988)
DT, IR and X-ray diffraction analyses have been carried out on 3 grain size fractions (1, 1-2 and 2-4 mu m) of sediments from the Central Indian Ocean Basin. Results indicate that there are 2 smectite minerals (montmorillonite ...
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 ...
