Sup(210)Pb, sup(230)Th, and sup(10)Be in Central Indian Basin seamount sediments: Signatures of degassing and hydrothermal alteration of recent origin
Isotopic (sup(210)Pb, sup(238)U-sup(230)Th, sup(10)Be), major and trace elements, and micromorphological and microchemical data, were used to identify recent (approx. 100 yrs) hydrothermal alteration of a greater than 200 ...
Radiolarian abundance and geochemistry of the surface-sediments from the Central Indian Basin: Inferences to Antarctic bottom water current
(Current Science Association, 1994)
The distribution trend of numbers of radiolarian shells/gram dry sediment, biogenic silica, organic carbon, and the carbon/nitrogen ratios in the surface sediments of the Central Indian Basin is similar. Ratios of two ...
Radiolarian zonation and volcanic ash layers in two Quaternary sediment cores from the Central Indian Ocean Basin
(Palaeontological Society of India, 1988)
Radiolarian abundance in two Quaternary sediment cores, collected from the Central Indian Basin, was studied and Nigrini's (1971) and Goll's (1980) zones are recognised. New radiolarian zones Collosphaera orthoconus, ...
