Rare earth elements in suspended and bottom sediments of the Mandovi estuary,central west coast of India: Influence of mining
(Elsevier, 2011)
Rare earth elements (REEs) in the suspended particulate matter (SPM) of the Mandovi estuary indicated that the mean total-REEs and light REE to heavy REE ratios are lower than that of the average suspended sediment in World ...
Verdine and glaucony facies from surficial sediments of the eastern continental margin of India
(Elsevier, 1995)
The present paper reports the first mineralogical description of green grains (verdine and glaucony) from sediments of the eastern continental margin of India. Only 24 of the 82 sediment samples studied, at depths between ...
Mercury speciation in coastal sediments from the central east coast of India by modified BCR method.
(Elsevier, 2014)
This is the first study to describe distribution and speciation of Hg in coastal sediments from the central east coast of India. The concentrations of Hg in the studied sediments were found to be much lower than the Hg ...
Determination of rare earth, major and trace elements in authigenic fraction of Andaman Sea (Northeastern Indian Ocean) sediments by inductively coupled plasma-mass spectrometry
(Elsevier, 2010)
Downcore variation of rare earth elements (REEs) in the authigenic Fe-Mn oxides of a sediment core (covering a record of last approx. 40 kyr) from the Andaman Sea, a part of the Indian Ocean shows distinctive positive Ce ...
Impact microcrater morphology on Australian microtektites
(Meteoritical Society, 2003)
Scanning electron microscopy of 137 Australian microtekties and fragments from 4 sediments cores in the Central Indian Ocean reveals more than 2000 impact-generated features in the size range of 0.3 to 600 mu m. Three ...
Granulometric analyses of pelites using a sedigraph: Examples from a Volcano-sedimentary environment
(Geological Society of India, 1993)
This article presents granulometric data of pelites (less than 40 microns) of mixed composition from a volcano-sedimentary environment. The sedigraph serves as an useful tool in the analyses of silt-clay fraction of marine ...
Distribution pattern and morphochemical relationships of manganese nodules from the Central Indian Basin
(Springer, 2001)
In the Central Indian Basin manganese nodule abundance was variable in all sediment types. Mean abundance varied from 1.5 in calcareous ooze to 10.2 kg/m sup(2) in terrigenous-siliceous ooze sediments. Nodule grade and ...
Extensive occurrence and genesis of authigenic carbonates from Krishna-Godavari offshore basin (Bay of Bengal): Possible influence of methane hydrates occurrences.
(Indian Geophysical Union, 2014)
We report here the extensive occurrences of authigenic carbonate nodules/concretions from gas hydrate bearing sediments. Bulk mineralogical compositions by X-Ray diffractometry and EDS (Energy Dispersive Spectrum) analysis ...
Structural characteristics of marine sedimentary humic acids by CP/MAS sup(13)C NMR spectroscopy
(Ifremer/ CNRS/ IRD/ Editions scientifiques et medicales Elsevier SAS. Tous droits reserves, 1998)
Humic acids from sediments of different depositional environments have been studied by solid-state sup(13)C NMR and the results compared with the traditional wet chemical analysis. Results obtained are well in agreement ...
Grain size analysis of sediments from the northern Andaman Sea: Comparison of laser diffraction and sieve-pipette techniques
(Coastal Education and Reserch Foundation, 2006)
A comparison has been made of sand, silt, and clay percentage of 118 samples from the Ayeyarwady continental shelf, northern Andaman Sea, measured by the sieve-laser diffraction technique and by classical sieve-pipette ...
