The evolution of the eastern Paleo-Asian Ocean (PAO) has controlled formation southeastern Central Asian Orogenic Belt (CAOB). However, history and final closure time PAO still remain controversial, which greatly restricts understanding process CAOB. To address these issues, we provide detailed zircon chronology Hf isotope geochemical data Paleozoic to Triassic magmatic rocks in We have identif...

Altaids in the Central Asian Orogenic Belt (CAOB) is one of world’s largest orogenic belts containing mineral deposits. Together with Junggar terrain they open an important window to study Paleozoic tectonic evolution CAOB. In this paper, we analyze a 637-km-long wide-angle refraction/reflection seismic profile across Altai-Eastern Tianshan belt southern Altaids, conducted September 2018 using ...

Abstract. The cross-correlation of ambient noise records registered by seismic networks has proven to be a valuable tool obtain new insights into the crustal structure at different scales. Based on 2 14 s period Rayleigh and Love dispersion data extracted from recorded 20 three-component broadband stations belonging two temporary experiments, we present first (i) upper-crustal (1–12 km) high-re...

This paper present new U–Pb geochronological data (LA-ICP MS on zircon) of granitoids from the Moroccan Meseta Variscan belt. Zircons Oulad Ouaslam granodiorite in Jebilet massif Western highlight a peak magmatic activity at 335.2 ± 0.8 Ma. In Eastern Meseta, ages obtained several facies High Moulouya complex restrained its to early Visean: 339.6 1.9 Ma for Perdreaux granite, 337 1.6 calc-alkal...

Abstract The “Rinkian belt” of West Greenland is a metamorphic terrain Paleoproterozoic age comprising: (1) the north Rinkian fold-thrust belt (FTB)—a pro- or fore-arc domain, highly deformed and metamorphosed with widespread anatexis; (2) Prøven Igneous Complex—a magmatic arc characterized by hypersthene granitic rocks (“charnockites”); (3) south FTB—an inverted back-arc basin; 4) continental ...

A variety of tectonic processes spread along the circum-Mediterranean orogenic belts driven by convergence major plates, episodes slab retreat and lateral vertical mantle flows. Here, we provide an updated view crustal stress strain-rate fields for Albanides belt in eastern Adria-Eurasia boundary. We framed a new geodetic-based source model 2019 Mw6.4 Durrёs earthquake light regional deformatio...

Introduction: The North Qilian orogenic belt, as the Northern branch of original Tethys tectonic domain, is important for reconstructing evolution ancient Tethys. However, history belt remains controversial. This study addresses this issue from a geochemical perspective. Methods: In study, comprehensive analysis geochronology, whole-rock geochemistry, clinopyroxene mineral zircon Ti crystalliza...

As an important tectonic unit of Eastern Tethyan domain, Sanjiang orogenic belt started from the expansion, subduction, subtraction and closure Paleozoic Paleo-Tethys Ocean, went through opening Neo-Tethys Ocean subduction collision process Indian continent ended in Himalayan comprehensive intracontinental convergence uplift orogeny, forming a giant composite composed several island arc belts s...

Marine siliceous rocks are widely distributed in the central orogenic belt (COB) of China and have a close connection to the geological evolution and metallogenesis. They display periodic distributions from Mesoproterozoic to Jurassic with positive peaks in the Mesoproterozoic, Cambrian--Ordovician, and Carboniferous--Permian and their deposition is enhanced by the tensional geological settings...
