Geochemistry of deep-sea sediment cores from the Central Indian Ocean Basin
(NISCAIR, New Delhi, 1993)
Four sediment cores from the Central Indian Ocean Basin (CIOB) were studied to characterise the coarse fraction (less than 63 mu), transition metal and major oxide contents. Transition metals (Mn, Cu, Ni, Zn) show enrichment ...
Australasian microtektites from the Central Indian Basin: Implications for ejecta distribution patterns
(Current Science Association, Bangalore, India, 1996)
Microtektites belonging to the Australasian tektite strewn field have been recovered in one (SK-16/176) out of three cores examined from the Central Indian Basin. The microtektites have been identified based on their ...
Origin and significance of high-grade phosphorite in a sediment core from the continental slope off Goa, India
(Current Science Association, Bangalore, India, 1995)
A phosphorite crust was found at 380-390 cm depth interval of a sediment core collected from the topographic high occurring on the continental slope off Goa. This crust is fragile and grey to light brown in colour. Carbonate ...
Phosphorite concretions in a sediment core from a bathymetric high off Goa, western continental margin of India
(Current Science Association, Bangalore, India, 1996)
A sediment core collected from a bathymetric high off Goa on the western continental margin of India, has yielded phosphorite concretions with an average Pd2O5 content of 32.75%, the P2O5 concentrations being highest ever ...
Evidence for recent hydrothermal activity in the Central Indian Basin
(Pergamon, 1997)
This study documents the first actual prof of recent intraplate volcanic-hydrothermal activity in the Central Indian Basin (CIB). Twenty-six surface sediments and a spade core (37 cm long) from the CIB were examined for ...
Trace elements in near-shore sediments along the east and west coasts of India
(Science and Technology Agency of Japan (JISTEC, STA), Japan, 1999)
To understand the distribution of trace elements and their controlling factors in the coastal regions of India. Some representative sediment samples from the nearshore regions were selected from the east and west coasts ...
Aeolian deposition of Arabia and Somalia sediments on the southwestern continental margin of India
(Current Science Association, Bangalore, India, 1996)
Kaolinite, smectite, illite and chlorite as major clay minerals and palygorskite and gibbsite in minor quantities have been recorded from the slope of southwestern continental margin of India. Contribution of kaolinite, ...
Controls on organic carbon distribution in sediments from the eastern Arabian Sea margin
(Springer, 1997)
Sediment cores from the upper continental slope of the eastern Arabian Sea have high organic carbon (OC), CaCO sub(3), and sand content at the top. The values decrease with increasing depth in the Holocene and Upper ...
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 ...
Organic carbon and humic acids in sediments of the Arabian Sea and factors governing their distribution
(Elsevier, 1994)
Organic carbon and humic acids in the sediments of the Arabian Sea show distinct regional variations to the south and north of 15~'N latitude. Significant variations are also observed from the shelf to the slope regions. ...
