We report new Sm–Nd whole rock-mineral isochron ages of 2514 ± 13 Ma (MSWD = 0.79) and 2651 ± 95
Ma (MSWD = 7.4) from two east coast dykes (ECD) of Southern Granulite Terrain (SGT), India. The
ages from the representative ...

Slope instability due to tectonic, hydrological and anthropogenic activities cause severe
landslides in Himalaya. Joshimath, a densely populated Himalayan town witnessed a catastrophic landslide
event during December ...
The Kaladgi basin is one of the major Paleoproterozoic rift basins in Peninsular India. Here we attempt to
reconstruct the architecture of the basin and evaluate the deep tectonics using magnetotelluric evidence. We ...
To investigate the transient strain rate of postseismic deformation associated with the highly
devastating December 26, 2004 Andaman–Sumatra earthquake (Mw 9.3), a combined
analysis have been done using GPS data and ...
This paper presents the results of a magnetovariational study undertaken over a basalt-covered region of western India which has been experiencing a swarm of seismic activity since early 1986. The most striking feature of ...
Magnetic Field Satellite (MAGSAT) data contains contribution from the earth's core, external currents and the crust; the data has been successfully utilised to derive information about each of these sources. Magsat provided ...
Geomagnetic variations, recorded through a two-phase magnetovariational study carried out along the Ganga-Yamuna valley of the Garhwal Himalaya, northwest India, are reduced to a set of induction arrows spanning a period ...
A palaeomagnetic and 40Ar/39Ar study is reported from a suiteof 41 mafic dykes comprising a dense E-W trending swarm intruding Archaean granitic basement near the southern margin of the Proterozoic Cuddapah basin in southern ...

Nighttime transient geomagnetic variations recorded by an array of 29 magnetometers in the equatorial region of north-northeast Brazil have been subjected to robust regression analysis in order to derive transfer functions ...
Asediment core collected from an area 100 miles south of the ODP Leg 116 (distal Bengal Fan) in the equatorial Indian Ocean was investigated for microfossils, mineralogy, mineral chemistry, magnetic susceptibility, grain ...
Systematic palaeoclimatic study of the glacio-lacustrine sediments using multiproxy data in
Pindari glacier area, Central Himalaya has helped in better understanding of the climatic
fluctuations since the last 7 Ka. The ...

The purpose of this study was to prove the direct correlation of a successions of gravel‐clay beds
recovered in borehole with the melt‐water pulses associated with the sea‐level oscillations indicated in the δ18O
record ...
This study investigates seismic anisotropy in the northeastern region of the Indian plate, including the Eastern Himalayan
front, Eastern Himalaya Syntaxis (EHS), Indo-Burmese subduction zone, Shillong Plateau, Assam ...
Volcanic eruptions are potential sources for generating the Earth’s free oscillations at spheroidal modes of 0S29 and 0S37 through acoustic resonant coupling between the Earth and its atmosphere. Then, does every volcano ...
Peninsular India is traversed by several major Paleoproterozoic rift basins, among which the Kaladgi rift basin is a prominent one. Here, we present results from Magnetotelluric (MT) studies in the eastern section of this ...
Wepresent an updated paleomagnetic pole from the Gwalior Sills in the Bundelkhand craton within the Northern India Block (NIB). Geochronological results from baddeleyite grains from one of the sills yielded an age of 1719 ...
