Analysis of magnetic anomalies in relation to Placer deposits and basement configuration off Mirya bay, Central West coast of India
(1988)The offshore ilmenite placers off Konkan, central west coast of India, have been surveyed by echosounding, shallow seismic profiling, magnetics, and seabed sampling. The magnetic data show two different types of anomalies: ... -
Analysis of multi-channel seismic reflection and magnetic data along 13 degrees N latitude across the Bay of Bengal
(American Geophysical Union, 1994)Analysis of the multi-channel seismic reflection, magnetic and bathymetric data collected along a transect, 1110 km long parallel to 13 degrees N lat. across the Bay of Bengal was made. The transect is from the continental ... -
Dating of the 85 degrees E Ridge (northeastern Indian Ocean) using marine magnetic anomalies
(Current Science Association, 2011)The 85 degrees E Ridge is a typical aseismic ridge in the northeastern Indian Ocean in view of the fact that it associates with exceptional gravity and magnetic signatures. The ridge possesses two different gravity anomalies: ... -
Delineation of structural lineaments from marine magnetic anomalies off Jonnalakonda, East Coast of India
(NISCAIR, New Delhi, 1991)Bathymetric and total magnetic intensity data off Jonnalakonda, south of Visakhapatnam, India have been collected. Magnetic anomaly contour map revealed that (1) the well developed magnetic anomaly occurring seaward side ... -
Delineation of structural lineaments from marine magnetic anomalies off Lawson's Bay (Visakhapatnam), East Coast of India
(CSIR-NISCAIR, 1987)Marine magnetic surveys have recorded total field anomalies that correspond to structural lineaments extending from the coast into the sea. The significant anomalies recorded in this area are along wavelength high amplitude ... -
Early tertiary seafloor spreading magnetic anomalies and paleo-propagators in the northern Arabian Sea
(Elsevier, 1998)Study of closely spaced new marine magnetic profiles, in conjunction with published magnetic data, provide an updated identification of linear magnetic anomalies in the northern Arabian Sea from the Owen Fracture Zone in ... -
Environmental magnetic studies on some Quaternary sediments of varied depositional settings in the Indian sub-continent
(Elsevier, 2007)The efficacy and limitations of routine environmental magnetic approaches to characterize and compare the Quaternary sediments of varied depositional settings (fluvial, fluvio-lacustrine and marine) from the Indian ... -
Evidence for seafloor spreading in the Laxmi Basin, northeastern Arabian Sea
(Elsevier, 1994)Marine magnetic anomaly data from the Laxmi Basin for the first time reveal the presence of fairly correlatable NNW-trending magnetic lineations. These magnetic lineations are symmetric about a central negative magnetic ... -
Evolution of the Late Cretaceous crust in the equatorial region of the Northern Indian Ocean and its implication in understanding the plate kinematics
(The Royal Astronomical Society, 2009)Analysis of 3100 km of newly acquired marine magnetic data, constrained by satellite and shipborne free air gravity anomalies, in the corridor between the 86°E fracture zone (FZ) and Ninetyeast Ridge, north of the equator ... -
Ferrobasalts from the Central Indian Ocean Basin
(Springer, 1999)The occurrence of ferrobasalts recovered from the Central Indian Ocean Basin crust generated at the Southeast Indian Ridge during a phase of moderate to fast spreading accretion (approx 110-190 mm/yr, full rate) is reported. ... -
General Expression for Spectrum of Magnetic Anomaly due to long Tabular body and its Characteristics
(CSIR-NISCAIR, 1980)A general expression for spectrum of magnetic anomalies-vertical, horizontal and total intensity - due to a long tabular body is derived which is used to estimate the body parameters. The analysis is extended to a marine ... -
Geological and geophysical surveys of Visakhapatnam coast
(Indian Association for Limnology and Oceanography, 1985)Continuous records of the total earth's magnetic field and the surface sediment samples from the ocean bottom have been collected off Ramakrishna Beach and Lawsons Bay along the Visakhapatnam Coast. The magnetic data has ... -
Geophysical signatures over and around the northern segment of the 85 degrees E Ridge, Mahanadi offshore, Eastern Continental Margin of India: Tectonic implications
(Elsevier, 2013)The nature and origin of the subsurface 85 degrees E Ridge in the Bay of Bengal has remained enigmatic till date despite several theories proposed by earlier researchers. We reinterpreted the recently acquired high quality ... -
InRidge program: Preliminary results from the first cruise
(Current Science Association, 1998)The first cruise under India's own Ridge research initiative, InRidge collected new data on bathymetry, free-air gravity and magnetic anomalies across the ridge axis between the Vema and Zhivago transform faults in the ... -
Magnetic and bathymetric investigations over the Vema Region of the Central Indian Ridge: Tectonic implications
