“…4) (Dai et al, 2013;Leary et al, 2016;Li et al, 2016). Although, when the ancestral YTR was formed is still debated (e.g., Lang and Huntington et al, 2014;Zeitler et al, 2014;Tremblay et al, 2015), the erosive drainage networks of the YTR would have flowed eastward and drive large-scale erosional exhumation on the southern edge of the LT before 10 Ma (Zeitler et al, 2014) or during ~22-8 Ma (Song et al, 2018). Alternatively, the rollback and northward underthrusting of the Indian plate was suggested to play a pivotal role in uplift and exhumation of the southern Lhasa terrane, represented by the rapid exhumation of the Kailas Formation at ca.…”

The history and geodynamic mechanisms of Cenozoic exhumation and denudation of the Lhasa terrane (LT), southern Tibetan Plateau, remain poorly constrained. Most previous studies investigating the exhumation of the LT have relied on extrapolating interpretations based on a few well-studied but small areas, which inevitably introduce bias. Here, our compilation of new and published thermochronologic ages are plotted against latitude, longitude, and elevation, to illustrate the distribution of cooling ages across broad regions of the LT. Primary results reveal that (1) the north LT experienced significant exhumation during 80-40 Ma; (2) compared with north LT, exhumation and erosion in the south LT continued after ~40 Ma; and (3) N-S striking rifting, E-W striking river incision, and thrusts led to continued local denudation of the south LT between 20-5 Ma.

“…An AFT experiment is a kind of dating technique using the amount and length of tracks in apatite crystals generated by 238 U fission to calculate a rock’s age (Flcischcr et al., 1965; Green, 1985; Hurford and Green, 1983), which is usually applied to study orogenic uplift history (Song et al., 2018; Zeitler et al., 1982; Zhu et al., 2005). The fission tracks in apatite crystals were affected by temperature (Duddy et al., 1988), such that the tracks’ length would decrease if the temperature exceeds 60 °C and would vanish when the temperature surpasses 110 ± 10°C (Fitzgerald et al., 1995).…”

The Juhugeng mining area in the Qilian Mountains is the only district of China where terrestrial gas hydrate has been found. This paper aimed at studying the gas migration for gas hydrates based on fluid inclusion and apatite fission track experiments with samples being collected in both the hanging wall (Triassic strata, non-hydrocarbon source rocks) and footwall (Jurassic strata, hydrocarbon source rocks) of drilling cores. Fluid inclusions are found in both the hanging wall and footwall, and are characterized by two generations: the first generation includes gaseous and liquid hydrocarbon fluid inclusions with the homogenization temperature of concomitant saline water inclusions being 83–115°C, and the second generation includes gaseous fluid inclusions with the concomitant homogenization temperature of saline water inclusions being 115–149 °C, suggesting two periods of gas migration. Combining with the reconstruction of the burial and thermal histories, the gas migration history can be elaborated as follows: (1) In the Late Paleogene period (>30 Ma), the gas in the footwall migrated to the hanging wall because of the thrusting of Triassic strata, with the temperature being more than 110 ± 10°C (derived from apatite fission track results), corresponding well with the homogenization temperature of the saline water inclusions of the first generation being 115–149 °C; (2) In the Late Neogene to Quaternary (<8 Ma), the study area were impacted by the intensive faults, leading to the second gas migration with a good match between temperature lower than 110 ± 10°C (derived from apatite fission track results) and the homogenization temperature of saline water inclusions in the second generation (83–115 °C), and the geological age of the second gas migration can be restricted from 8 to 1.8 Ma. The permafrost was formed in Quaternary, so the controversial gas hydrate formation pattern can be determined that the gas should be accumulated before the permafrost was formed.
