Behavior of rare earth elements in coexisting manganese macronodules, micronodules, and sediments from the central Indian Basin
(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 ...
Influence of seabed topography on the distribution of manganese nodules and associated features in the Central Indian Basin: A study based on photographic observations
(Elsevier, 1993)
The distribution of manganese nodules and associated rock outcrops and sediment cover in the Central Indian Basin (10 degrees-16 degrees S, 73 degrees-82 degrees E), were studied from seabed photographs in relation to ...
Characterizing Indian Ocean manganese nodule-bearing seafloor using multi-beam angular backscatter
(Springer, 2004)
Application of quantitative angular backscatter modelling to manganese nodule-bearing areas of the Central Indian Ocean Basin (CIOB) has been initiated at NIO during the year 1998. Studies were aimed to establish the ...
Benthic disturbance and monitoring experiment in the Central Indian Ocean Basin
(Int. Society of Offshore and Polar Engineering, Colorado, USA, 1997)
Environmental impact assessment studies for deep-sea manganese nodule mining have been initiated in the Central indian Ocean Basin since 1995. As a part of the first phase for collecting the benthic baseline data, echosounding, ...
Changes in geotechnical properties of sediments from the Central Indian Basin induced by disturbance experiment
(Taylor and Francis, 2005)
During the Indian Deep-sea Environment Experiment (INDEX) conducted in the Central Indian Basin to simulate nodule mining activity, the sediments were physically disturbed, lifted from the seafloor, and then redeposited ...
Ferromanganese nodules and their associated sediments from the Central Indian Ocean Basin: Rare earth element geochemistry
(Taylor and Francis, 2001)
The rare earth element (REE) distribution in nine deep-sea ferromanganese nodules and their associated siliceous sediments from the Central Indian Ocean Basin (CIOB) have been studied to elucidate the REE relationship among ...
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 ...
Distribution of manganese nodules, rocks and sediments in the Central Indian Ocean Basin: Factors influencing performance of mining system
(Publ. and Inf. Dir., New Delhi, India, 1994)
Manganese nodule abundances in the Central Indian Ocean Basin (CIOB) as noted from seabed photographs (nil to 18.4 kg/m sup(2)) and grabs (nil to 21.5 kg/m sup(2)) are variable. The relative abundance varies from zero to ...
Two layers of Australian impact ejecta in the Indian Ocean
(Meteoritical Society, 2003)
Only 2 Australian tektites have been found in the Indian Ocean, and both are associated with surficial sediments. Cores from both locations are collected, where the tektites have been reported. The microtektites in these ...
