The Alxa Block is located in the middle part of Central Asian orogenic belt, which coupling belt North China, Tarim, and Kazakhstan Plates. east–west-trending deep faults control stratigraphic distribution magmatic activity region. To detect EW-trending ore-controlling structures, a 440 km NS section magnetotelluric sounding was conducted from Minle to Ejinaqi. phase tensor electrical principal...

The Encruzilhada Block lies between the eastern hinterland and western foreland of Dom Feliciano Belt (southern Brazil) its tectonic meaning in orogenic evolution belt is still poorly understood. Its low magnetic signal similar to that supracrustal sequences, whereas high gammaspectrometric appears due post-collisional granitoids. Satellite image lineament analysis points similarities foreland,...

late neoproterozoic-early cambrian schists have been occurred in southwest of zanjan city from the soltanieh belt. the soltanieh belt in northwest of iran is uplifted basement of precambrian-paleozoic in main central iran zone and includes outcrops of precambrian, paleozoic and mesozoic formations. late neoproterozoic-early cambrian schists, the oldest stratigraphy unit in the region, consist o...

Accretionary and collisional orogeny are often accompanied by the disturbance of geothermal gradient, leading to high-temperature metamorphism. High-temperature metamorphic rocks significant in their ability help reconstruction thermal histories orogenic belts. The Tianshan Orogenic Belt, at southwest margin Central Asian is a record long-term subduction–collision–post-collision process that ha...
