Located at the center of the Eurasian continent and accommodating as much as 44% of the modern crustal shortening between India and Siberia (Knapp, ), the Tianshan orogenic belt (TOB) is one of the youngest ( m) orogenic belts in the world. It provides a natural laboratory for studying the intracontinental deformation by: The Qinling orogen has 2 kinds of orogenic basements. The main orogenic phase was characterized by the oblique subduction and collision of 3 plates at 2 suture zones. There are a number of vertical accretionary structures under the control of deep-seated thermo-tectonic processes. The present 3-D model of the Qinling is a f > lyover-like by: The Zhaosu–Tekesi Depression, located to the northern margin of the South Tianshan orogenic belt (STB), is an ideal region for investigating Paleozoic orogenic processes and later modifications.

1. Introduction. The E-W trending Qinling orogenic belt (QOB), located between the North China Craton (NCC) and the Yangtze Craton (YZC), is one of the major composite collisional orogens in East Asia (Wu and Zheng, ), with a complex tectonic history (Dong et al., ).The QOB has been divided into the NQB and SQB based on geological features, and geographically sub-divided into the Cited by: Xiba Granitic Pluton in the Qinling Orogenic Belt, Central China: Its Petrogenesis and Tectonic Implications Article in Acta Geologica Sinica 86(5) October with 65 . Abstract The Lajishan orogenic belt is one of the E-W-trending Caledonian orogenic belts within the Qinling-Qilian orogenic system. It was formed upon the Jiningian basement by intensive. Evolution history of the orogenic belt can be divided into subduction stage ( Ma) and collision stage ( Ma). The formation of the orogenic belt caused the convergence between the Siberian and North China Plates during the late Devonian. Suture zone corresponding to the mélange belt extends from Erdaojing, Qagan Ura to by:
The Qinling orogenic belt is thus an Indosinian‐Yanshanian collision‐detachment zone. The so‐called “Caledonian orogeny” in the Qinling Orogenic Belt records a succession of extensional and partial melting events in the continental by: Request PDF | Geologic framework and tectonic evolution of the Qinling Orogen, Central China | The geologic framework of the Qinling orogen was built up through interplay of three blocks, the. This orogenic belt is not only an important target to decipher the tectonic evolution of China and eastern Asia, but is also an ideal laboratory to study orogenic processes and the geodynamics of. Qinling Orogenic belt Lower crust Tethyan Adakitic intrusive rocks of ∼– Ma were discovered in the North Qilian orogenic belt, the western section of the Central Orogenic System (COS) in China. These adakitic rocks were lower crust melts rather than slab melts as indicated by their crustal Ce/Pb, Nb/U, Ti/Eu, and Nd/Sm ratios and.
