Abstract Knowledge of the nature of the earliest metamorphism experienced by collisional orogenic belts is essential for reconstruction of tectonic processes that build high mountain chains and their environmental consequences. Understanding the metamorphic nature of Eohimalayan-phase orogeny of the Himalayan orogen, one of the typical ...

Abstract Recognition of accretionary tectonics in ancient orogenic collages is important for reconstructing the long-term subduction, accretion, and erosional history of fossil convergent margins, and for understanding crustal growth and supercontinent assembly.

article i nfo Eocene (40-42 Ma) basaltic dykes in the Gaoligong-Tengliang belt, eastern Tibet, are characterized by high Na2 O( 2-4%), in contrast with the widespread post-collisional potassic and ultrapotassic rocks in the Tibetan plateau. Despite the ubiquitous negative Nb anomalies, these dykes have relatively high Nb and Zr contents, making them ...

The Tianshan, Junggar and Altay orogenic belts in northwest China (Xinjiang) are part of the huge Central Asian Orogenic Belt (CAOB), which extends from the Uralides in the west to the Pacific Ocean margin of eastern Asia. The CAOB is a complex collage of fragments of ancient microcontinents and subduction-related island arc terranes, fragments of ...

Tectonics and Metallogeny of the Tethyan Orogenic Belt
2016Abstract The Tethyan orogenic belt stretches from the Alps, through the Carpathians and Balkans, Taurides and Caucasus, Zagros, Makran, and Himalayas, to Indochina and into the southwest Pacific Ocean. It represents a complete Wilson Cycle, from opening and closure of the Paleotethys Ocean in the mid-Paleozoic to the Late Triassic ...

The Qilian Orogen in the northeastern margin of Qinghai-Tibetan plateau records the tectonic history of the Proto-Tethyan Ocean from its initial subduction to final closure. However, the timing of subduction initiation, subduction polarity, and arc-continent collision processes remain controversial.

AbstractThe Buqingshan Tectonic Mélange Belt in the south margin of the East Kunlun Orogen, located in west section of Buqingshan–A'nyemaqen Suture Zone, is one of the key areas to understand continental tectonics and continental dynamics of China. This paper reports zircon U–Pb dating results and geochemistry of the Manite granodiorite (rock mass) in ...
