Ferromanganese oxides from Mid-Indian ridge, seamounts and abyssal plains from the Indian Ocean
(CSIR-NISCAIR, 1989)Mineralogical and chemical investigations show that todorokite is the only Mn mineral in the Mid-Indian Ridge ferromanganese, coatings, delta MnO2 in the seamount crusts, and well crystallised todorokite and minor amounts ... -
Internal microfeatures of manganese nodules from the Central Indian Ocean
(Elsevier, 1988)The internal features of manganese nodules from abyssal hills ranging in height from 600 to 880 m and the nodules from abyssal plains in the Central Indian Ocean have been studied. Nodules from the abyssal hills show mainly ... -
Optimum sampling interval for evaluating ferromanganese nodule resources in the central Indian Ocean
(Springer, 2001)A study to estimate manganese nodule abundance (weight of nodules in kg/m sup(2)) was carried out in a small area of the abyssal plains covering a one-degree square block in the central Indian Basin. Abundance was assessed ... -
Partitioning and speciation of trace metal diagenesis in differing depositional environments in the sediments of the Oman margin
(Springer, 2005)Organic-rich sediment samples collected from a transect within, and below, the Oman Margin oxygen minimum zone (OMZ)were analysed using a sequential leaching technique to characterise the diagenetic behaviour and speciation ...
