This paper is primarily concerned with seismically imaging details in the mantle at an intermediate scale length between the large scales of regional and global tomography and the small scales of reflection profiles and outcrops. This range is roughly 0.1– 1 kmbab10–10 km, where a is the scale. We consider the implications of several models for mantle evolution in a convecting mantle, and possi...

As relics of oceanic lithosphere, ophiolites exposed in the East Kunlun region are crucial for deciphering evolution from Proto-Tethys to Paleo-Tethys. Two ophiolite belts have been recognized Orogenic Belt: northern Heishan-Dagele-Qingshuiquan Ophiolite Belt and southern Muzitag-A’nyemaqen Belt. Most basaltic rocks belt show apparent geochemical features enriched mid-ocean ridge basalts, with ...

Abstract A magnetotelluric (MT) study across the Red Lake greenstone belt of western Superior craton, Canada, images a 50-km-long north-dipping conductor (<20 Ω·m) at 20–25 km depth and subvertical conductors spatially correlated with crustal-scale shear zones large orogenic gold deposits. The are interpreted to be conductivity signature deep crustal source auriferous fluids pathways sys...

Abstract. Neogene indentation of the Adriatic plate into Europe led to major modifications Alpine orogenic structures and style deformation in Eastern Southern Alps. The Giudicarie Belt is a prime example this, as it offsets entire edifice; its activity has been kinematically linked strike-slip faulting lateral extrusion Remaining questions on exact role this fold-and-thrust belt structure orog...

At least seventeen different Fusarium spp. associated with head blight have been found worldwide. In India, Fusarium head blight occurs all along the wheat growing Himalayan belt up to a height of 1500 meters. Farmers in these areas depend on rainfed wheat for their household consumption and use it as a seed stock for the next season. Since the disease has appeared only occasionally so far, it ...

Background After decades of research carried out in India by several government organizations, a decision has been taken to generate 1000 MW of electricity using geothermal energy by 2022. Geothermal energy is perceived as a hidden potential in the earth’s crust. The USA, Indonesia, Philippines, Italy, Mexico and Iceland are the leading nations in utilizing this potential. Research efforts in I...
