A note on geochemistry of surface sediments from Krishna-Godavari basin, East Coast of India
(The Geological Society of India, 2008)
A closely spaced 75 surface sediments drawn from ‘Gas Hydrate` Project taken up by National Institute of Oceanography on a regional scale from the Krishna-Godavari Basin (Latitude I5 degrees 35 minutes to 16 degrees 20 ...
Coupling between suboxic condition in sediments of the western Bay of Bengal and southwest monsoon intensification: A geochemical study
(Elsevier, 2013)
Reconstruction of paleo-redox conditions in a radiocarbon (14C) dated sediment core (SK-218/1), covering the past 45 ka (thousand calendar years), collected from the western Bay of Bengal (Lat: 14 degrees 02′N; Long: 82 ...
Ferromanganese nodules and their associated sediments from the Central Indian Ocean Basin: Rare earth element geochemistry
(Taylor and Francis, 2001)
The rare earth element (REE) distribution in nine deep-sea ferromanganese nodules and their associated siliceous sediments from the Central Indian Ocean Basin (CIOB) have been studied to elucidate the REE relationship among ...
Diagenetic remobilization of rare earth elements in a sediment core from the central Indian Basin
(NISCAIR, CSIR, 1997)
Rare earth elements (REE) distribution in a 36 cm long sediment box core from the Central Indian Basin is studied. REE concentration is generally higher in the upper oxic zone than in intermediate suboxic zone suggesting ...
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 ...
Productivity fluctuations in the southeastern Arabian Sea during the last 140 ka
(Elsevier, 2003)
Detailed analyses of multiple geochemical productivity proxies such as calcium carbonate, biogenic opal, biogenic Ba, organic carbon and total nitrogen have been carried out on a sediment core from the southeastern Arabian ...
Fe speciation and Fe/Al ratio in the sediments of southeastern Arabian Sea as an indicator of climate change
(Elsevier, 2012)
Aluminium, titanium and iron are the major lithogeneous contributors to the marine sediment and their abundance varies strikingly with the intensity of monsoonal precipitation. Al and Ti concentrations in a sediment core ...
Chemistry of surface sediment along a north-south transect across the equator in the Central Indian Basin: An assessment of biogenic and detrital influences on elemental burial on the seafloor
(Elsevier, 1998)
The detailed chemistry of the surface sediment collected along a north-south transect across the equator in the Central Indian Ocean suggest that: biogenic sedimentation north of equator is dominated by carbonate ooze and ...
Major, trace, and rare earth elements in the sediments of the Central Indian Ocean Basin: Their source and distribution
(Taylor and Francis, 2001)
The distribution maps of elements show that highest concentrations of Mn, Cu, Ni, Zn, Co, and biogenic opal in the surface sediment occurs between 10 degrees S and 16 degrees S latitude, where diagenetic ferromanganese ...
Drift pumice in the central Indian Ocean Basin: Geochemical evidence
(Elsevier, 2008)
Abundant white to light grey-coloured pumice without ferromanganese oxide coating occurs within the Quaternary sediments of the Central Indian Ocean Basin (CIOB). Two distinct groups of pumice are identified from their ...
