    Cerium anomaly variations in ferromanganese nodules and crusts from the Indian Ocean 

    Nath, B.N.; Roelandts, I.; Sudhakar, M.; Pluger, W.L.; Balaram, V. (Elsevier, 1994)
    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 ...

    Basalt microlapilli in deep sea sediments of Indian Ocean in the vicinity of Vityaz fracture zone 

    Nath, B.N.; Iyer, S.D. (Geological Society of India, 1989)
    Two cores recovered from the flanks of Mid-India oceanic ridge in the vicinity of Vityaz fracture zone consist of discrete pyroclastic layers at various depths. These layers are composed of coarse-grained, angular basaltic ...

    Ferromanganese oxides from Mid-Indian ridge, seamounts and abyssal plains from the Indian Ocean 

    Rao, P.S.; Pattan, J.N. (CSIR-NISCAIR, 1989)
    Mineralogical and chemical investigations show that todorokite is the only Mn mineral in the Mid-Indian Ridge ferromanganese, coatings, delta MnO2 in the seamount crusts, and well crystallised todorokite and minor amounts ...

    Morphological and interlayer geochemical studies on manganese nodules from the southwestern Carlsberg ridge 

    Valsangkar, A.B.; Rajamanickam, G.V.; Karisiddaiah, S.M.; Siddiquie, H.N. (Elsevier, 1988)
    Mixed facies of manganese nodules from the southwestern Carlberg Ridge have been analysed for Mn, Fe, Ni, Cu, Co and Zn. Seventy one analyses including the averages presented for outer layer, inner layer and near-core ...

    Internal microfeatures of manganese nodules from the Central Indian Ocean 

    Pattan, J.N. (Elsevier, 1988)
    The internal features of manganese nodules from abyssal hills ranging in height from 600 to 880 m and the nodules from abyssal plains in the Central Indian Ocean have been studied. Nodules from the abyssal hills show mainly ...

    Superficial mineral resources of the Indian Ocean 

    Siddiquie, H.N.; Hashimi, N.H.; Gujar, A.R.; Valsangkar, A.B. (Elsevier, 1984)
    The sea floor of the Indian Ocean and the continental margins bordering the ocean are covered by a wide variety of terrigenous, biogenous and anthigenic mineral deposits. The biogenous deposits in the Indian Ocean comprise ...

    Geochemical evidence of terrigenous influence in deep-sea sediments upto 8°S in the Central Indian basin 

    Nath, B.N.; Rao, V.P.; Becker, K.P. (Elsevier, 1989)
    Thirty-two representative deep-sea sediment samples have been studied from three manganese nodule-bearing environments in the Central Indian Basin: diatomaceous-radiolarian ooze-clay, pelagic brown clay and calcareous ooze. ...

    Effect of sediment-water interface 'boundary layer' on exposure of nodules and their abundance: a study from seabed photos 

    Sharma, R. (Geological Society of India, 1989)
    The results obtained from seabed photos and boomerang grab samples reveal a striking similarity in distribution patterns of size classes of polymetallic nodules. Due to partial sediment cover, there is a 'fractionation' ...

    Grade distributions in manganese nodules of Central Indian Ocean Basin 

    Sudhakar, M. (Current Science Association, 1989)
    Data concerning to geological setting physical characteristics and bulk chemical composition of the nodules sampled from CIOB were stored in the Computer Data Bank of this Institute. Bulk chemical composition of nodules, ...
