Underwater geomorphology as a function of the variations in ferromanganese nodule characters in the Indian Ocean
(Current Science Association, 1989)
Ferromanganese nodules from three areas in the northern part of the Central Indian Ocean Basin have been studied. Statistical analysis shows significant variations in morphological and physical characters of nodules between ...
Ore grade manganese nodules from the central Indian basin: an evaluation
(1989)
Comparative studies on manganese nodules from two different areas (S and R) in the Central Indian Basin show distinct variations in their composition, grade (percent Ni + Cu), and abundance (kg/m2), which are explained in ...
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 ...
Variability of Mn, Fe, Ni, Cu and Co in manganese nodules from the Central Indian Ocean Basin
(Elsevier, 1989)
The trace element variations in manganese nodules from the Central Indian Basin have been related to the underlying sediment type. Percentages of Mn, Cu and Ni are high in nodules occurring in siliceous sediments compared ...
