Grain size studies on the nearshore sediments of Jaigad, Ambwah and Varvada Bays, Maharashtra
(Geological Society of India, 1997)
Bivariate plots of the textural parameter data suggest overlapping environments, such as river/beach to JB, beach/dune/river to AB and dune/beach to VB sediments.
Verdine and glaucony facies from surficial sediments of the eastern continental margin of India
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 ...
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 ...
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 ...
Response of infaunal macrobenthos to the sediment granulometry in a tropical continental margine southwest coast of India
Surficial sediment samples, collected from the continental margin of the southwest coast of India in July 2004, were examined for the grain size and soft-bottom macrobenthic fauna, to understand the sediment granulometry ...
Distribution of grain size and clay minerals in sediments from the INDEX area, central Indian Basin
(Taylor and Francis, 2000)
The granulometry of 21 box core sediments from five selected sites in the Central Indian Basin (CIB) have been studied to understand the sediment size characteristics in the Pioneer area before the benthic disturbance ...
First phase monitoring studies of simulated benthic disturbance delineating movement of fine particles in the Central Indian Basin
(Taylor and Francis, 2005)
Benthic disturbance due to future deep-sea polymetallic nodule mining would involve extensive sediment plume generation and resedimentation on the sea floor. In order to evaluate the effects of resedimentation on benthic ...
Rare-earth elements and uranium in phosphatic nodules from the continental margins of India
(Society for Sedimentary Geology (SEPM), Tulsa, USA, 2000)
A sediment core collected from a bathymetric high off Goa on the western continental margin of India has yielded phosphatic nodules at various subsurface depths (at 110, 150, 305 355, 435, 500, 505 and 525 cm). The nodules ...
Estimation of mean grain size of seafloor sediments using neural network
The feasibility of an artificial neural network based approach is investigated to estimate the values of mean grain size of seafloor sediments using four dominant echo features, extracted from acoustic backscatter data. ...
Physical properties of a long sediment core from the central Indian Basin
(Geological Survey and Mines Bureau, Dehiwala, Sri Lanka, 1997)
In a 7.5 m-long box core, collected at 9 degrees S and 77 degrees E from 5400 m water depth from the Central Indian Basin, geotechnical properties clearly reflect the Plio-Pleistocene boundary. It is marked by a drastic ...
