Size analyses and geochemistry of ferromanganese nodules from the Central Indian Ocean Basin
(1989)
Ferromanganese nodules collected during the 13th cruise of the M.V. Skandi Surveyor in 1987 cover a very large area, 71 424 km super(2) in the Central Indian Ocean. The area consists of 13 nodule types, which are grouped ...
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 ...
Size, surface texture, chemical composition and mineralogy interrelations in ferromanganese nodules of central Indian Ocean
(CSIR-NISCAIR, 1989)
Fiftyseven ferromanganese nodules, classified into 3 size class (4,4-6 and 6-8 cm diam.), from the siliceous sediments of central Indian Ocean were analysed for transition metals and representative sample from each size ...
Surficial Sediments of the Continental Shelf off Karnataka
(Geological Society of India, 1981)
The continental shelf in this area is about 80 km wide and the edge of the shelf varies between 90 and 120 m water depth. Geologically modern fine-grained clastic sediments occur between the water depth. Geologically modern ...
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 ...
