Application of inversion techniques on marine magnetic data: Andaman shelf
(Geological Society of India, 1994)Analysis of the total intensity magnetic data over the western Andaman shelf has been carried out for determination of depth to magnetic basement using the Analytical Signal and Wemer Deconvolution methods. The basement ... -
Automatic interpretation of magnetic data using Euler deconvolution with nonlinear background
(Birkhauser, 2007)The voluminous gravity and magnetic data sets demand automatic interpretation techniques like Naudy, Euler and Werner deconvolution. Of these techniques, the Euler deconvolution has become a popular choice because the ... -
Basement structure beneath the innershelf off Mahabalipuram to Palar River, east coast of India
(NISCAIR, CSIR, 1995)Magnetic data along three coastal parallel profiles over the innershelf (30-50 m water depth) off Mahabalipuram recorded short wavelength and high amplitude (peak to peak of the order of 200-700 nT) anomalies. Two linear ... -
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 ... -
Extension of Gundlakamma River Fault over eastern continental margin of India
(Current Science Association, 2010)The bathymetry, magnetic and shallow seismic data were collected between the water depths of 13 to 26 meters north of Ongole to study the tectonic significance of Gundlakamma river towards offshore. The bathymetry in the ... -
Geophysical investigations over a segment of the Central Indian Ridge, Indian Ocean
(Springer, 1997)Swath bathymetric, gravity, and magnetic studies were carried out over a 55 km long segment of the Central Indian Ridge. The ridge is characterized by 12 to 15 km wide rift valley bounded by steep walls and prominent ... -
Geophysical studies over a segment of the Carlsberg Ridge, Indian Ocean
(Elsevier, 1993)The study of magnetic, gravity and bathymetric data over a segment of Carlsberg Ridge between 3 degrees and 4 degrees N lat., and 63 degrees 30' and 64 degrees 30'E long. revealed the presence of a prominent 57 degrees W ... -
Magnetic and bathymetric investigations over the Vema Region of the Central Indian Ridge: Tectonic implications
(Elsevier, 2000)Magnetic and bathymetric data were collected along N50 degrees E profiles in the Vema Region (7-12 degrees S, 64-70 degrees E) across five ridge segments of the Central Indian Ridge (CIR). Anomalies up to A5 (10 Ma), ... -
Magnetic basement in the central Bay of Bengal
(Kluwer, 2002)Analyses of about 6000 km of processed magnetic data in the central Bay of Bengal using Analytical Signal Processing and Werner Deconvolution techniques revealed that the depth to top of the magnetic basement varies between ... -
Magnetic expression of some major lineaments and cretaceous quiet zone in the Bay of Bengal
(Springer, 1997)Magnetic data over the eastern continental margin of India and adjacent Bengal fan demarcate two major lineaments. A high amplitude N - S trending lineation of the Cauvery offshore Basin corresponds to the offshore fragment ... -
Neotectonism - An offshore evidence from eastern continental shelf off Visakhapatnam
(Current Science Association, Bangalore, India, 1999)A minor tremor measuring 4.5 on the Richter scale occurred around 4.58 p.m. on 18 December 1995, with its epicentre located in the Bay of Bengal, nearly 30 km east of Vizianagaram on the Andhra Pradesh coast. The location ... -
New insights into the tectonic evolution of the Andaman basin, northeast Indian Ocean
(Elsevier, 2004)Multibeam swath bathymetry data acquired over an area of about 30 000 km 2 ,together with magnetic and single channel seismic data, have been analyzed to understand the tectonic evolution of the Andaman basin,northeast ... -
