The so-called ‘mesothermal’ gold deposits are associated with regionally metamorphosed terranes of all ages. Ores were formed during compressional to transpressional deformation processes at convergent plate margins in accretionary and collisional orogens. In both types of orogen, hydrated marine sedimentary and volcanic rocks have been added to continental margins during tens to some 100 milli...

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...

The Orkhon-Selenge Belt is a Late Permian to Early Triassic volcanic plutonic belt located in northern Mongolia and part of the Central Asian Orogenic Belt. Selenge Complex, which Belt, key area for studying tectonic magmatic evolution This study aims contribute understanding geodynamic by investigating petrology, geochemistry geochronology rocks region. Our results indicate that intrusive were...

Based on the analysis of known geodynamic models that explain processes in various settings Meso-Cenozoic stages development continental margins and tectonic-magmatic events accompanying these processes, as well basis our own data obtained a result many years research axial structure Central Asian Fold Belt-Mongol-Okhotsk orogenic belt influence interdependent structures post-Mesozoic evolution...
