Influence of seamount topography on the local facies variation in ferromanganese deposits in the Indian Ocean
(Elsevier, 1988)
The morphology and chemistry of ferromanganese nodules and encrustations from a seamount in the Central Indian Ocean Basin show local variations. Nodules from the summit of the seamount have sporadic distribution, are less ...
Ferro-manganese encrustation on the tympanic bulla of a minke whale from Central Indian Ocean Basin
(CSIR-NISCAIR, 1987)
Ear bone of a minke whale (Balaenoptera acutorostrata) was collected from 5200 m water depth with thin coating of Fe-Mn oxide on its surface. The Fe-Mn coating material was similar in nature and ratios Mn/Fe and Cu + Ni/Co ...
Classification and inter-element relationships of ferromanganese nodules from the Central Indian Ocean Basin
(1987)
The chemical composition of polymetallic nodule samples from 180 locations in the Central Indian Ocean Basin based on 600 chemical analyses has been investigated. These nodules contain a Mn/Fe ratio varying from 0.96 to ...
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 ...
Geochemical trends in the sediments and manganese nodules from a part of the Central Indian Basin
(Geological Society of India, 1994)
Geochemical analyses of eighteen surface sediments samples collected from an area between 1 degree-15 degrees S latitudes and 73 degrees-87 degrees E longitudes exhibit significant variation in their chemical ...
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 ...
