Basalt microlapilli in deep sea sediments of Indian Ocean in the vicinity of Vityaz fracture zone
(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 ...
Geochemical evidence of terrigenous influence in deep-sea sediments upto 8°S in the Central Indian basin
(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
(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' ...
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 ...
