Ferromanganese oxides from Mid-Indian ridge, seamounts and abyssal plains from the Indian Ocean
(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
(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 ...
Carbonate mineralogy and faunal relationship in tropical shallow water marine sediments: Cape Comorin, India
(Elsevier, 1982)
The carbonate mineralogy of Recent sediments from the western and eastern continental shelves around Cape Comorin off the southern tip of India was determined by X-ray diffraction analyses. The results show that in the ...
Mineralogy of polymetallic nodules and associated sediments from the Central Indian Ocean Basin
(Elsevier, 1987)
Todorokite is the dominant mineral phase in the nodules of the northern Central Indian Ocean Basin. These nodules are characterised by a rough surface texture, are relatively rich in Mn, Cu and Ni, and are associated with ...
Distribution of iron, manganese, cobalt and nickel in sediment cores of the northeastern Arabian Sea
(Geological Society of India, 1976)
A study of the distribution of iron, manganese, cobalt and nickel in sediment cores from the shelf, slope and basin regions of Bombay-Kathiawar coast of India shows that cobalt and nickel are derived from the overlying sea ...
Australasian microtektites in a substrate: A new constraint on ferromanganese crust accumulation rates
(Elsevier, 1994)
Microtektites belonging to the Australasian tektite strewn field are found in the substrate of a ferromanganese crust dredged from the Central Indian Basin. They are identified on their physical appearance, geographic ...
