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. ... -
Depositional processes inferred from the log probability distribution
(Hindustan Publishing Corporation, Delhi, 1993) -
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 ... -
Hydrocarbon prospects of the western continental slope of India as indicatEd. by surficial enrichment of organic carbon
(Indian Petroleum Publishers, Dehra Dun, India, 1993)The sediments from the continental mid-slope (150-1500 m depth) of the western margin are highly enriched in organic carbon (upto 16%) occurring as a long and wide band off Bombay to southern tip of India. Organic carbon ... -
Evidence of climatic change during Holocene in the nearshore regions of Konkan (central west coast of India
(Museo Geologico di Bologna, 1993)In order to understand the paleoenvironmental setting of the nearshore area of the central west coast of India, three vibro-cores from the Kalbadevi Bay, from a depth range of 6-12 m were analysed for sedimentological, ... -
Quantitative estimation of seafloor features from photographs and their application to nodule mining
(Taylor and Francis, 1993)Methods developed for quantitative estimation of seafloor features from seabed photographs and their application for estimation of nodule sizes, coverage, abundance, burial, sediment thickness, extent of rock exposure, ... -
Influences of Holocene sea level, regional tectonics, and fluvial, gravity and slope currents induced sedimentation on the regional geomorphology of the continental slope off northwestern India
(Elsevier, 1993)Regional geomorphology derived from echosounding and bathymetric data (lines of a total of 12,000 km), depth to basement, regional deep seated tectonic features, surficial sediment distribution and Holocene sedimentation ... -
Evidences of climatic variations during Late Pleistocene- Holocene in the eastern Bay of Bengal
(Current Science Association, Bangalore, India, 1993)Based upon the variations of clay minerals, sediment texture, heavy mineral assemblage and sup(230)Th excess in the Late Pleistocene sediments of a hemipelagic core from the eastern Bay of Bengal (2713 m water depth), 35 ... -
Late Pleistocene sedimentation: A case study of the central Indian Ocean Basin
(Pergamon, 1993)Concentration-depth profiles of excess sup(230)Th have been measured in five sediment cores from the central Indian Ocean Basin to determine their accumulation rates and excess sup(230)Th flux to the depositional environment. ... -
Remote sensing approach to determine net shore drift direction- A case study along the central east coast of India
(Coastal Research Foundation, 1993) -
Mean proloculus size, delta super(13) C and delta super(18) O variations in recent benthic foraminifera from the west coast of India and their climatic implications
(Indian Society of Earth Sciences, Calcutta, 1993)The interrelationship between mean proloculus size (MPS), delta super(18) O and delta super(13) C vatiations in benthic foraminiferal species Rotalidium annectens and their relation with temperature (T) and salinity (S) ... -

Studies on sound signal scattering from varying seabed sediments of the western continental shelf of India: Cochin to Mangalore
(Cochin University of Science and Technology, Cochin, 1993)A study on the interaction effect of the acoustic signal with three different sediment type seabottoms off the shelf area between Cochin and Mangalore of the west coast of India is performed. Analyses by means of Probability ... -
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 ... -
Subsurface precambrian ridge on the continental shelf of western India between Coondapoor and Kasaragod
(Elsevier, 1993)Bathymetric and magnetic data along seven ENE-WSW and seventeen NNW-SSE and N-S profiles collected on the southwestern continental shelf of India between Coondapoor and Kasaragod within water depths of 20-2000 m are studied. ... -
Spatial and temporal variations of carbonate content in the beach and nearshore environments off Goa, west coast of India
(NISCAIR, New Delhi, 1993)Sediment samples collected from dunes, beaches (Calangute, Baina and Colva) and nearshore environments along the coast of Goa, have been analysed for their carbonate content. The results show the presence of very high ... -
Reactivation of precambrian faults on the southwestern continental margin of India: Evidence from gravity anomalies
(Elsevier, 1993)Gravimetric and bathymetric studies on the southwestern continental margin of India confirm the extension of onshore NW-SE-, NNW-SSE-, N-S-, NE-SW-, ENE-WSW- and E-W-trending lineaments of Precambrian age over a considerable ... -
