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,...

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...

Gabbroic pluton of Bagham is located in southeastern Ardestan and has intruded into Eocene volacanic rocks. The study area is a part of Central Iranian zone and Urumieh-Dokhtar magmatic belt. Clinopyroxene, plagioclase and amphibole are main minerals in the pluton. Mineral chemistry studies show that clinopyroxenes are augite and are plotted in almost medium pressure field. The clinopyroxene co...

Abstract The western Tianshan Gold Belt hosts numerous giant and large gold deposits that have been formed during the late Paleozoic amalgamation of orogen. However, little is known about their exhumation histories Mesozoic to Cenozoic intracontinental evolution Carboniferous Katebasu orogenic deposit in northwestern China a new discovery within Belt, it shares many similarities with other belt...

The E-vergent Northern Apennines formed by Oligocene-Miocene convergence and westward subduction of Adria beneath Europe. Extension ensued in the Mid-Late Miocene reflecting lower plate roll-back causing opening back-arc Tyrrhenian Sea. Post-orogenic extension is commonly advocated as main driver exhumation belt's inner domain high-pressure/low-temperature (HP-LT) rock units. Acquadolce Subunit...

The Rzeszow thrust-top basin was formed on the active Skole thrust sheet of Outer Carpathian fold-and-thrust  belt and filled with Miocene syntectonic sediments. New seismic 3D, well field data were used to define relationship between sedimentation tectonic activity to establish synkinematic context of the basin-fill architecture. evolution controlled by frontal thrust hinterland thrusts develo...
