A brief study on the imprints of seismo tectonic activities in the crust of central and southern Bay of Bengal
(Association of Exploration Geophysicists, 2007)Bathymetry, magnetic and shallow seismic data collected north and south off Visakhapatnam revealed the extension of onshore lineaments to offshore. Stability of the area has been studied from the physical properties of ... -
An experimental study of velocities under pressure for ancient oceanic rocks
(Springer, 1991)Seismic velocities of Indus suture rock types from Dras-Sanko-Kargil, Kashmir Himalaya, as a function of pressure up to 10 kbar were studied. The high-pressure measurements on the rocks reflect the depthwise increase in ... -
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: ... -
Early oceanic opening off Western India-Pakistan margin: The Gop Basin revisited
(Elsevier, 2009)The Deccan Traps, one of the best known examples of rapid flood basalt, are considered as marking of the inception of a mantle plume on the Indian continental lithosphere. Their emplacement may be associated with the ... -
Morphological characteristics and emplacement mechanism of the seamounts in the Central Indian Ocean Basin
(Elsevier, 2007)The morphotectonic features of the Central Indian Ocean Basin (CIOB) provide information regarding the development of the basin. Multibeam mapping of the CIOB reveals presence of abundant isolated seamounts and seamount ... -
Seamounts an additional tool to confirm the nature of the crust and to locate possible mineral resources for dredging
(Taylor and Francis, 1998)Study of bathymetric data for the distal Bengal Fan reveals the presence of positive topographic features resembling seamount. These features exhibit a relief of about 800 m above the surrounding seafloor at 4,400 m and ... -
Some geodynamic complexities related to the evolution of Bengal Fan and the neotectonic activity of the south Indian shield
(Current Science Association, Bangalore, 1997)After three decades of the International Indian Ocean Expedition (IIOE) and in spite of extensive geophysical data collected during the last one decade, the geodynamics of the Bengal Fan and the Peninsular shield at the ... -
Structure and evolution of the Afanasy Nikitin seamount, buried hills and 85 degrees E Ridge in the northeastern Indian Ocean
(Elsevier, 2003)Geophysical data of the Afanasy Nikitin seamount (ANS), partly buried hills and 85 degrees E Ridge in the northeastern Indian Ocean were studied together with published seismic refraction results to understand genesis and ... -
Yttrium and rare earth element contents in seamount cobalt crusts in the Indian Ocean
(Current Science Association, 2012)Cobalt-rich Fe-Mn crusts occur on almost all seamounts and plateaus of the world oceans. Fe-Mn crusts are formed through layer-by-layer accretion of colloidal precipitates from cold ambient seawater onto exposed seamount ...
