Late Pleistocene carbonate sediments and rocks on the western continental shelf of India
(Pune: Nowrosjee Wadia College, 1989)
Behavior of rare earth elements in coexisting manganese macronodules, micronodules, and sediments from the central Indian Basin
(Taylor and Francis, 1994)
Associated manganese macronodules, micronodules, and sediments from the Central Indian Basin (CIB) were analyzed for major, trace, and rare earth elements (REE) to understand REE carrier phases and their fractionation ...
Cerium anomaly variations in ferromanganese nodules and crusts from the Indian Ocean
Fifty analyses of rare earth elements as well as mineralogical studies have been carried out on a suite of manganese nodules and crusts from the Central Indian Basin and the Western Indian Ocean. The aim was to identify ...
Size distribution and carbonate content of the sediments of the western shelf of India
(National Institute of Sciences of India, 1968)
Sediment samples collected during the 25th cruise of I.N.S. KISTNA (Indian Programme of I.I.O.E.) were analysed for grain size and carbonate content. The shelf sediments show well defined zonation, except where river-borne ...
Morphological variations in the polymetallic nodules from selected stations in the Central Indian Ocean
Polymetallic nodules from the Central Indian Ocean largely range in size from 2 to 6 cm. The smaller nodules (4 cm) are subspheroidal to spheroidal in shape and with the increase in size, nodules become more discoidal and ...
Our changing coastlines
Our coastlines keep alive the sense of continuing creation and of the relentless drive of life In recent years, much has been done both to understand the processes that underlie their creation and to exploit their environment ...
Mineralogy of the carbonate sediments - western continental shelf of India
An X-ray diffraction study of forty-six sediment samples and three oolitic limestone samples from the western continental shelf of India shows that aragonite is the dominant carbonate mineral (99% maximum), followed by ...
Computation of nodule abundance from seabed photos
This paper was selected for presentation by the OTC Program Committee following review of information contained in an abstract submitted by the author(s). Contents of the paper, as presented, have not been reviewed by the ...
Morphology of an uncharted seamount from Central Indian Basin
The morphology of a seamount at 12 degrees 35'S and 76 degrees 16'E is studied. This conical seamount has a maximum height of 1275 m (water depth 4135 m) and covers an area of about 189 sq km. The maximum basal extension ...
Underwater geomorphology as a function of the variations in ferromanganese nodule characters in the Indian Ocean
(Current Science Association, 1989)
Ferromanganese nodules from three areas in the northern part of the Central Indian Ocean Basin have been studied. Statistical analysis shows significant variations in morphological and physical characters of nodules between ...
