Ground-motion prediction equations (GMPEs) play a crucial role for estimating the seismic hazard in any region using either a deterministic or a probabilistic approach. Indeed, they represent a reliable and fast tool to ...

Basalts occur as sub-alkaline tholeiites in the Naga ophiolite belt. They bear an E-MORB affinity ascribed to aqueous fluid addition from a dehydrating oceanic crust in a supra-subduction zone during the Indo-Burma ...

A palaeomagnetic study of 115 samples (328 specimens) from 22 sites of the Mid- to Upper Cretaceous Bagh Group underlying the Deccan Traps in the Man valley (22° 20′N, 75° 5′E) of the Narmada Basin is reported. A characteristic ...

Inversion of vertical electrical sounding (VES) data, especially from the crystalline hard rock area, assumes a special significance for groundwater exploration. Here we used a newly developed algorithm based on the Bayesian ...

Magnetovariational fields recorded by an array of magnetometers in Saurashtra and the surrounding regions have been analysed to infer the electrical conductivity distribution of the region. Only night-time magnetovariational ...

High resolution aeromagnetic (HRAM) data collected recently over the Kutch Rift Basin have been analysed to look below the salt plains, grassland and sediments and to understand the Basin configuration of this seismically ...

The Lonar crater in Maharashtra state, India, has been completely excavated on the Deccan Traps basalt (approximately 65 Ma) at approximately 570 ± 47 ka by an oblique impact of a possible chondritic asteroid that struck ...

A number of mafic intrusive bodies (mostly dykes) are exposed in the Chhotanagpur Gneissic Terrain (CGT). Most dykes trend in ENE–WSW to E–W following major structural trends of the region. These metabasite dykes show ...
