Geochemical and Sr–Nd–Hf isotopic constraints on the origin of Late Triassic granitoids from the Qinling orogen, central China: Implications for a continental arc to continent–continent collision

TL;DR: In this article, the authors presented an overview of key geological observations in the South China Block with respect to its Phanerozoic tectonics, and proposed a geodynamic model for the Mesozoic evolution of the SCB, which is characterized by strong thrusting/transpression, anatexic granitic magmatism, high-grade metamorphism and the poor involvement of the juvenile mantle derived rocks.

TL;DR: The Qinling Orogenic Belt (QOB) as mentioned in this paper is a composite orogenic belt that witnessed four major episodes of accretion and collision between discrete continental blocks, such as the North China Block, North Qinling Block and the South China Block.

TL;DR: The results of zircon U-Pb dating indicate that granitoid magmatism in the Qinling Orogen mainly occurred in four distinct periods: the Neoproterozoic (979-711), Paleozoic(507-400), and Early (252-185) Ma) and Late (158-100) Mesozoic as discussed by the authors.

TL;DR: The Central China Orogenic belt (CCOB) as mentioned in this paper comprises, from the east to the west, the Tongbai-Dabie, Qinling, Qilian and Kunlun Orogens, and preserves abundant and important amalgamation records of the North China, South China, Qaidam, Tarim and Qiangtang Blocks.

TL;DR: In this paper, the trace-element geochemical properties of the adakites (termed "adakites") of modern island and continental arcs are shown to be consistent with a derivation by partial melting of the subducted slab, and in particular that subducting lithosphere younger than 25 Myr seems to be required for slab melting to occur.

TL;DR: In this article, the authors present a method to discriminate between Tectonic Environments using data from Geochemical Data and Radiogenic Isotopes and Isotope Data.

TL;DR: This article evaluated subducting sediments on a global basis in order to better define their chemical systematics and to determine both regional and global average compositions, and then used these compositions to assess the importance of sediments to arc volcanism and crust-mantle recycling, and to re-evaluate the chemical composition of the continental crust.
