Thermochronology of Early Paleozoic collisional and subduction–collisional structures of Central Asia

Abstract

Abstract The thermochronology of the Early Paleozoic collisional and subduction–collisional systems and blueschist complexes of the Central Asian Orogenic Belt has been reconstructed by the proposed method of “through” isotope dating. The evolution of these geologic structures is divided into short synchronous stages of active thermal events related to large-scale mantle–crustal magmatism, high-pressure/low-temperature and high-temperature/low-pressure metamorphism, and intense tectonic deformations. The plume activity of different intensities, both in intraoceanic and intracontinental environments, is presumed to be the deep mechanism of synchronization.
