Ferro-manganese oxide growth on shark teeth from cenral Indian Ocean basin
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 ...
Analysis of magnetic anomalies in relation to Placer deposits and basement configuration off Mirya bay, Central West coast of India
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: ...

Clay mineral distribution in the shelf sediments off the northern part of the east coast of india
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 ...
Nature, distribution and origin of clay minerals in grain size fractions of sediments from manganese nodule field, Central Indian Ocean Basin
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 ...
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
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 ...
Petrology of offshore basalts of Bombay harbour area, west coast of India
Recent marine geological and geophysical surveys indicate that the Deccan Traps extend to the offshore area of Bombay. Cores from bore holes in Deccan Traps collected from Bombay Harbour have been classified as basalts, ...
Aeolian sand transport and its effects on the stability of Miramar-Caranzalem beach
(Indian Association for Limnology and Oceanography, 1988)
Removal of sand by wind from the beach at Miramar-Caranzalem, Goa, has been found to effect its stability over a relatively longer time scale. This aeolian sand transport has been computed for this strip of the beach ...
Distribution of some biochemical compounds in the sediments of the Bay of Bengal
Surficial sediment samples collected from the continental shelf and slope of the Bay of Bengal were studied for the distribution of organic carbon and its constituent fractions such as carbohydrates, proteins, amino acids ...
