SHORT NOTE: The tectonic evolution of the Chuya-Kurai zone (Siberian Altai mountains) by means of multi-method chronology
Abstract
The Phanerozoic tectonic evolution of the Chuya-Kurai zone was studied by means of zircon U/Pb-dating, apatite fission track (AFT) and apatite (U-Th)/He (AHe) thermochronology on basement rocks. Our results suggest that multiple magmatic episodes during the Paleozoic, related to the accretion-collision tectonics in Central Asia, affected our study area. Mesozoic and Cenozoic basement cooling events are interpreted as periods of tectonic reactivation. We propose a new tectonic model for Late Cenozoic evolution of the Chuya-Kurai zone.
