“…The fission-track age of the apatite in the Eastern Tibet-Western Sichuan and Yunnan areas suggested two age peak values, the 13-10 Ma and since 5 Ma, respectively ( Figure 5(e)). The peak age of 13-10 Ma was obtained from the apatite of rocks from the Gongga Mountain of eastern Tibet, Litang [78,79] , Chayudemula Rock Body [4] , and the Gaoligong Mountain [80] . Since 5 Ma, the fission-track age was also obtained in the regions near the Dulong River, northwest of Yunnan [81] , and in the Red River Fault of western Yunnan [82] , in addition to the above-mentioned areas.…”

Geological mapping data (1:250000) in the Qinghai-Tibet Plateau and its adjacent regions reveal the sediment sequences, distribution and tectonic evolution of the 92 Tertiary remnant basins. SouthernTibet and the Yecheng area in Xinjiang, located at southern and northwestern margins of the Qinghai-Tibet Plateau, respectively, were parts of the Neo-Tethys remnant sea in the Paleogene. In southern Tibet, both the subabyssal and abyssal sequences occur at the Gyangze, Saga, Guoyala, and Sangmai areas. The deep-water facies successions outcrop in the west, whereas the shallow-water facies sequences in the east, indicating the east to the west retreat of the Neo-Tethys Ocean. The retreat of the Neo-Tethys Ocean in the east was contributed to the earlier tectonic uplift of the eastern Qinghai-Tibet Plateau. The uplift process of the Plateau from the Late Cretaceous to Pliocene is described as follows: During the Late Cretaceous, tectonic uplift of the Qinghai-Tibet Plateau occurred in the northeastern part and the configuration of the Qinghai-Tibet Plateau was characterized by rise in the northeast and depression in the west. In the Paleocene-Eocene interval, the Tengchong-Baingoin and Kuyake-Golmud areas experienced local tectonic uplifting, the West Kunlun uplift zone broadened easterly, the Qilian uplift zone broadened southerly, and the Songpan-Garzê uplift zone shrank easterly. The Oligocene configuration of the Qinghai-Tibet Plateau was characterized by mountain chains rising along its margins and sedimentary basins in the central part because of tectonic uplifts of the Gangdisê and the Himalaya blocks. Meanwhile, the Kunlun-Altyn-Qilian uplift zones have also broadened southerly and northerly. In contrast, the great uplift zones of the Gangdisê, the Himalaya, the Karakorum, and the Kunlun blocks characterize the paleogeographic contours of the Qinghai-Tibet Plateau during the Miocene-Pliocene. Additionally, the thermochronological data on tectonic uplift events in southern Tibet, West Kunlun Mountains, Altyn Tagh, eastern Tibet, and western Sichuan all suggest that the most intense deformation occurred at 13-8 Ma and since 5 Ma, respectively, corresponding to two great uplift periods in Neogene. As a result, turnover of paleogeographic configuration of the Qinghai-Tibet Plateau occurred during the Neogene, experiencing a change from high contours in the east in the pre-Oligocene to high contours in the west at the end-Pliocene. The uplift of the Qinghai-Tibet Plateau during the Cenozoic was episodic, and the uplifts of various blocks within the Plateau were spatially and chronologically different.

The Sichuan Basin is a superimposition basin composed of terrestrial and marine sediments that is well known for its abundant petroleum resources. Thermal history reconstruction using paleogeothermal indicators, including vitrinite reflectance and thermochronological data, shows that different structural subsections of the Sichuan Basin have experienced various paleogeothermal episodes since the Paleozoic. The lower structural subsection comprising the Lower Paleozoic to Middle Permian (Pz-P 2 ) successions experienced a high paleogeothermal gradient (23.0-42.6°C/km) at the end of the Middle Permian (P 2 ), whereas the upper structural subsection comprising Late Permian to Mesozoic strata underwent a relatively lower paleogeothermal gradient (13.2-26.9°C/km) at the beginning of the denudation (Late Cretaceous or Paleocene in the different regions). During the denudation period, the Sichuan Basin experienced a successive cooling episode. The high paleogeothermal gradient resulted from an intensive thermal event correlated to the Emeishan mantle plume. The heat flow value reached 124.0 mW/m 2 in the southwestern basin near the center of the Emeishan large igneous province. The low geothermal gradient episode with heat flow ranging from 31.2 to 70.0 mW/m 2 may be related to the foreland basin evolution. The cooling event is a result of the continuous uplift and denudation of the basin. paleotemperature gradient, paleo-heat flow, vitrinite reflectance, Emeishan mantle plume, Sichuan Basin Citation:

“…By apatite U-Th/He and fission-track age dating of a series of granites along the gorges of the Dadu River, Anning River and Yalong River, Clark et al [36] demonstrated a rapid uplift stage of 13-9 Ma on the eastern margin of the Tibetan Plateau. Rapid uplift and exhumation at 13-9 Ma were also detected by AFT age records from the Longmen Mountains and Gongga Mountains in the western Sichuan [35,37], Zayu in the eastern Tibet [38], and the Gaoligong Mountains in the western Yunnan [39], suggesting widespread uplift effects on the eastern margin of the Tibetan Plateau throughout this period of rapid uplift. There are more AFT ages since 5 Ma, and they have been determined along the Dulong River and the Red River in western Yunnan as well as in the areas mentioned above [40,41].…”

“…In recent years, more and more thermochronological data from western Sichuan and western Yunnan have also allowed us to portray the tectonic uplift processes of these areas in detail. For example, using AFT age dating and AFT length thermal history modeling of granites along the Garzê-Litang fault and the Longmenshan fault, Lai et al [35] found two periods of rapid exhumation cooling, 20-16 and since about 5 Ma. By apatite U-Th/He and fission-track age dating of a series of granites along the gorges of the Dadu River, Anning River and Yalong River, Clark et al [36] demonstrated a rapid uplift stage of 13-9 Ma on the eastern margin of the Tibetan Plateau.…”

Four intensive uplift periods, i.e., Ma in the Himalayas of the southern Tibet), and since about 5 Ma, can be determined on the Tibetan Plateau by synthetical analysis of low-temperature thermo-chronology data, sedimentary deposit records, and structural deformation records of different areas. The strong tectonic uplift periods in different areas on the Tibetan Plateau are penecontemporaneous, except for the Himalayan area of the southern Tibet, where a rapid uplift and exhumation period, controlled by the activity of the South Tibetan Detachment System faults, occurred during 18-13 Ma. These strong uplift and exhumation periods correspond well to intensive deformation activity periods, suggesting tectonically-controlled uplift and exhumation. The deposit records, such as the distribution of coarse clastic sediments, the distribution of tectonically-controlled basins, stratigraphic discontinuousness or unconformity, and fault-controlled geomorphologic evolution, also match well with the strong uplift and exhumation periods. Expanding processes of the plateau are also discussed. Tibetan Plateau, Cenozoic, intensive tectonic uplift and exhumation periods, plateau growth and expansion Citation:Wang G C, Cao K, Zhang K X, et al. Spatio-temporal framework of tectonic uplift stages of the Many researches have focused on the uplift processes of the Tibetan Plateau because it is the highest and largest plateau in the world and has a strong influence on the global climatic changes. Researchers have tried to quantitatively constrain the details of the uplift and exhumation processes in different parts of the plateau by using multidisciplinary approaches, including low-temperature thermo-chronology, paleontology, climatology, paleogeography, paleogeobarometry, and stable isotope, etc. They have also tried to study the dynamics of the tectonic uplift of the plateau by analyzing the Cenozoic structural deformation pattern and magma evolution. More and more data show that the tectonic processes of the Tibetan Plateau during the Cenozoic are characteristic of distinct stages and obvious diversity from area to area. Both tectonic uplift processes and development of the corresponding deposition and structural deformation exhibit the spatial-temporal diversity of the uplift and exhumation. This paper will review and analyze the spatial-temporal framework of tectonic uplift stages of the Tibetan Plateau in the Cenozoic based on low-temperature thermo-chronology data, sedimentary deposit records, and structural deformation records of different areas on the plateau.
