abstract = "The Tannuola Terrane of Tuva, which is located in the northern part of the Central Asian Fold Belt, formed as a result of island-arc and accretionary-collision events in the Early Paleozoic. Further tectonic evolution of the terrane is related to a multiple reactivations of large and mostly normal fault structures. In the middle Paleozoic, the extension of the crystalline basement of the terrane led to the active uplift of mafic melts along the faults to the surface and formation of subalkaline igneous rocks. The Mesozoic and Cenozoic igneous complexes within the Tannuola Terrane are unknown; thus, its tectonic evolution in the Mesozoic and Cenozoic could be considered only after a sedimentary record, which is preserved in the Mesozoic intermountain depressions of Tuva and adjacent Cenozoic Ubsunur Basin. This geological information, however, is insufficient for an exhaustive consideration of the regional tectonic regime taking into account the lack of confirmation of present-day precise methods. The understanding the Mesozoic–Cenozoic tectonic evolution of the Tannuola Terrane is impossible without the analysis of data on low-temperature thermochronology for rocks of the crystalline basement. In our study, fission-track analysis of apatite from 12 samples of the early Paleozoic granitoids of the Tannuola Terrane is conducted in order to recognize the stages of activation and tectonic stability within the absolute time scale. The analysis showed a wide range of ages from 83.4 ± 4.7 (Late Cretaceous) to 35.5 ± 2.2 (late Eocene) Ma at variation of the mean fission-track length from 11.4 to 12.3 µm. The modeling of the thermal evolution of the basement of the Tannuola Terrane, which is based on these data, indicated three stages of tectonic activation of various origins and intensities divided by stages of tectonic quiet periods for the last ~185 million years: (i) ~185–135 Ma (Jurassic–Cretaceous), (ii) ~90–35 Ma (Cretaceous–Paleogene), and (iii) ~15–0 Ma (Neogene–Quaternary).",
