Neogene oceanographic variations recorded in manganese nodules from the Somali Basin
(Elsevier, 1993)
A detailed study of a nodule from the Somali Basin datEd. by sup(230)Th sub(excess) was correlated with the paleoceanographic events recorded in Site 236 (Leg 24) Deep Sea Drilling Project (DSDP) cores. Tentative indications ...
Manganese micronodules: A possible indicator of sedimentary environments
(Elsevier, 1993)
Manganese micronodule distribution, size, internal features and chemical composition as well as the composition of associated sediments have been determined in eight sediment cores taken from the siliceous ooze area of the ...
Geochemistry of calcareous sediments from the SW Carlsberg Ridge: Evidence for deeper carbonate compensation depth
(NISCAIR, CSIR, 1995)
Concentration of Mn, Fe, Ni, Co, Zn, Ca, Mg, K, Al, Si, Ti, P and CaCO sub(3) show wide range for the calcareous sediments from SW Carlsberg Ridge (CR). Compared with the average pelagic clays, the CR sediments are enriched ...
Manganese nodule distribution in different topographic domains of the central Indian Basin
(Taylor and Francis, 1993)
Manganese nodule distribution is primarily influencEd. by seafloor topography. Nodule distribution at 479 locations vis-a-vis seabed topography is studiEd. by superimposing sampling location on the topographic profile and ...
Mineral chemistry of Carlsberg Ridge basalts at 3 degrees 35'- 3 degrees 41' N
(Springer, 1993)
Mineral chemical analyses of transitional basalts from the Carlsberg Ridge show plagioclase (An approximately 87 mole %), phenocrysts, and microphenocrysts have a K sub(2)O depletion as compared to the laths (approximately ...
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 ...
Alteration of basaltic glasses from the Central Indian Ocean
(Geological Society of India, 1999)
Textural, mineralogical and compositional characteristics of basaltic glasses from the Central Indian Ocean show them to be altered to varying extents through their interaction with the seawater, resulting in the formation ...
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 ...
Fresh pumice from the Central Indian Basin: A Krakatau 1883 signature
(Elsevier, 1995)
The occurrence of pumice in the Central Indian Basin (CIB) has been a controversy. Some are of the opinion that these pumices are erupted from a volcano along the Ninetyeast ridge while others suggest the Indonesian are ...
Dissolved aluminium in the surface microlayer of the eastern Arabian Sea
(Elsevier, 1993)
Measurements of dissolved aluminium (Al) in surface microlayer (SML) samples from the eastern Arabian Sea during the southwest (summer) and northwast (winter) monsoon periods have revealed much higher concentrations (23-657 ...
