The Minas-Bahia orogeny juxtaposed Archean crustal fragments and Paleoproterozoic magmatic arcs to form the São Francisco-Congo Paleocontinent by Rhyacian (ca. 2.05 Ga). Unravelling Minas segment of Orogenic Belt (MBO) is an important key understanding role in construction Columbia Supercontinent. Orosirian 1.9 Ga) final amalgamation was preceded a complex history accretion nuclei Proterozoic a...

A global tectonic regionalization, GTR1, has been constructed for use in seismological studies of aspherical heterogeneity. Three oceanic regions are defined by equal increments in the square root of crustal age (25and lO0-m.y. isochrons), and three continental regions are distinguished according to their generalized tectonic behavior during the Phanerozoic (Precambrian shields and platforms, P...

The Central Asian Orogenic Belt was characterized by a long-lived accretionary history from Neoproterozoic to Paleozoic, followed collisional phase of orogeny in the latest Paleozoic with closure Paleo-Asian Ocean. However, Ni-Cu sulfide mineralization associated mantle-derived mafic magmas relatively short-lived. Thus, coherence between protracted and transient sulfide-bearing magmatism is dif...

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...

This work assessed the age distribution of Cadomian/Pan-African orogenic events (550-590 and 605-790Ma, respectively) in several zones Iberian Massif by means detrital inherited zircon analysis compilation.
