    Behavior of rare earth elements in coexisting manganese macronodules, micronodules, and sediments from the central Indian Basin 

    Pattan, J.N.; Colley, S.; Higgs, N.C. (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 ...

    Morphological variations in the polymetallic nodules from selected stations in the Central Indian Ocean 

    Mukhopadhyay, R. (Springer, 1987)
    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 ...

    Morphology of an uncharted seamount from Central Indian Basin 

    Kodagali, V.N. (Elsevier, 1989)
    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 

    Mukhopadhyay, R.; Banerjee, G. (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 ...

    Ore grade manganese nodules from the central Indian basin: an evaluation 

    Sudhakar, M. (1989)
    Comparative studies on manganese nodules from two different areas (S and R) in the Central Indian Basin show distinct variations in their composition, grade (percent Ni + Cu), and abundance (kg/m2), which are explained in ...

    Size analyses and geochemistry of ferromanganese nodules from the Central Indian Ocean Basin 

    Valsangkar, A.B.; Khadge, N.H. (1989)
    Ferromanganese nodules collected during the 13th cruise of the M.V. Skandi Surveyor in 1987 cover a very large area, 71 424 km super(2) in the Central Indian Ocean. The area consists of 13 nodule types, which are grouped ...

    Influence of regional and local topography on the distribution of polymetallic nodules in Central Indian Ocean Basin 

    Kodagali, V.N. (Springer, 1988)
    Detailed bathymetric surveys from part of the Central Indian Ocean revealed several bathymetric features such as hills, slopes, valleys, and plains. Areas with a local relief of a few to hundreds of meters generally have ...

    Nodules of the Central Indian Ocean Basin 

    Banakar, V.K.; Kodagali, V.N. (New Delhi: Dep Ocean Dev, 1988)
    The Central Indian Ocean Basin (CIOB) extends from 0 degree S to 25 degrees S latitudes and 70 degrees E to 90 degrees E longitudes The major portion of CIOB is an abyssal plain and the plains are believed to be developed ...

    Radiolarian zonation and volcanic ash layers in two Quaternary sediment cores from the Central Indian Ocean Basin 

    Gupta, S.M. (Palaeontological Society of India, 1988)
    Radiolarian abundance in two Quaternary sediment cores, collected from the Central Indian Basin, was studied and Nigrini's (1971) and Goll's (1980) zones are recognised. New radiolarian zones Collosphaera orthoconus, ...

    Paleogene ichthyoliths from the substrates of ferromanganese encrustations and nuclei of manganese nodules from the Central Indian Basin 

    Gupta, S.M. (Palaeontological Society of India, 1987)
    Ichthyoliths, the phosphatic microscopic skeletal debris of the fishes are found in the substrates and the nuclei of ferromanganese encrustations and the nodules collected from the Central Indian Ocean Basin. About thirty ...
