“…6 displays the ET calculation of quartz minerals of one combined profile according to Eqs. (2) and (3), E and s given in Table 5, and the corresponding TL apparent ages are given in Table 3 and 4. Other independent information about the thermal regime structure of the studied area, such as independent present and paleo-temperature records of the strata, heat flow data of the interested locations and so on [19,23] is referred to for comparison with the counterparts suggested by equivalent temperature ET.…”

“…Minerals, such as apatite, zircon, titanite, potassium feldspar, illite, smectite, kerogen and so on, which were buried in sedimentary basins, plausibly recorded the changing rules of above information. Thermochronometers in sedimentary basins can be used to explore these rules, for example, fission track and (U,Th)/He dating of apatite and zircon, Ar/Ar dating of potassium feldspar [2] etc.…”

Good reproducibility of quartz thermal stimulated luminescence phenomenon offers the possibility of dating geological events in the subsurface and exploring environmental temperature history. As sandstones in basins generally experienced one certain pattern of thermal history due to effects of temporal and spatial dependent temperature fields, the quartz minerals extracted from these sandstones can be evaluated to explore the thermal regime structure information by thermoluminescence analyzing technique. In terms of equivalence for certain burial depths in the petroleum basin, the mean quantitative temperature field was investigated using both the quartz thermoluminescence apparent age method and laboratory isothermal thermoluminescence simulation measurements. The result shows that the variations of both thermoluminescence glow-curve pattern and intensity of certain natural thermoluminescence peaks correlate well with the environmental temperature field at corresponding burial depths where the quartz grains were extracted. The quartz natural thermoluminescence glow-curves peaks shift to high temperature and the thermoluminescence intensity reduction results from the increase of both environmental temperature and burial time for quartz due to deepening burial depth. Both the additive dose thermoluminescence (TL) and isothermal TL (SA-ITL) techniques were used for quartz mineral TL dating and the resultant apparent ages agree well with each other, and thus one parameter called equivalent temperature was tentatively presented and deducted from apparent TL ages of quartz minerals to evaluate the basin's thermal regime structure. Quartz thermoluminescence signal can be recognized as one potential paleothermometer if the good correlation of calculated equivalent temperature of buried quartz mineral with other paleothermometers can be supported by more lines of future independent geological evidence.

“…Low‐temperature (low‐T) thermochronology methods, including zircon/apatite U‐Th/He (ZHe and AHe, respectively) and apatite fission track (AFT), have been widely used to reconstruct burial histories and exhumation processes of sedimentary basins [e.g., Garver et al , ; Armstrong , ]. Here we present a suite of low‐T thermochronology data for locations covering an N‐S sampling transect across the Xigaze fore‐arc basin near Xigaze (Figures and ), which is a the widest and most continuous exposed record of the well‐studied lower basin Cretaceous sequence [e.g., Einsele et al , ; Wan et al , ; Wang et al , ; An et al , ] and is likely to provide a more complete thermal history record.…”

India‐Asia convergence: Insights from burial and exhumation of the Xigaze fore‐arc basin, south Tibet

The composite fore‐arc/syncollisional Xigaze basin in south Tibet preserves a key record of India‐Asia collision. New apatite fission track and zircon (U‐Th)/He data from an N‐S transect across the preserved fore‐arc basin sequence near Xigaze show a consistent northward Late Cretaceous to middle Miocene younging trend, while coexisting apatite (U‐Th‐Sm)/He ages are all Miocene. Corresponding detrital zircon U‐Pb data are also reported for constraining the Cretaceous depositional ages of the Xigaze basin sequence in the region. Thermal history modeling indicates that the basin experienced northward propagating episodic exhumation, along with a northward migration of the depocenter and a pre‐existing Cenozoic syncollisional basin sequence which had been removed. In the southern part, fore‐arc exhumation commenced in the Late Cretaceous (~89 ± 2 Ma). Following transition to a syncollisional basin in the Paleocene, sedimentation in the central and northern Xigaze basin continued until the latest Eocene (~34 ± 4 Ma). Ongoing folding and thrusting (e.g., Great Counter Thrusts) caused by progressive plate convergence during late Oligocene‐early Miocene time resulted in regional uplift and considerable basin denudation, which fed two fluvial basins along its northern and southern flanks and exposed the basement ophiolite. Subsequent incision of the Yarlung River resulted in Miocene cooling in the region. Different episodes in the exhumation history of the Xigaze basin, caused by thrusting of an accretionary wedge and ophiolitic basement, can be linked to changes in India‐Asia convergence rates and the changing subduction pattern of the Indian and Neo‐Tethyan slabs.

“…Five grains were analyzed per sample to reveal possible single-grain age dispersion, common especially in detrital samples (e.g. House, Farley, & Kohn, 1999;Armstrong, 2005). As reference, mean AHe ages with 1σ error and variation of the single-grain ages from the mean age are reported ( Table 2).…”

Post‐orogenic thermal history and exhumation of the northern Appalachian Basin: Low‐temperature thermochronologic constraints

Apatite fission‐track (AFT) thermochronology and (U‐Th)/He (AHe) dating, combined with paleothermometers and independent geologic constraints, are used to model the thermal history of Devonian Catskill delta wedge strata. The timing and rates of cooling determines the likely post‐orogenic exhumation history of the northern Appalachian Foreland Basin (NAB) in New York and Pennsylvania. AFT ages generally young from west to east, decreasing from ~185 to 120 Ma. AHe single‐grain ages range from ~188 to 116 Ma. Models show that this part of the Appalachian foreland basin experienced a non‐uniform, multi‐stage cooling history. Cooling rates vary over time, ~1–2 °C/Myr in the Early Jurassic to Early Cretaceous, ~0.15–0.25 °C/Myr from the Early Cretaceous to Late Cenozoic, and ~1–2 °C/Myr beginning in the Miocene. Our results from the Mesozoic are broadly consistent with earlier studies, but with the integration of multiple thermochronometers and multi‐kinetic annealing algorithms in newer inverse thermal modeling programs, we constrain a Late Cenozoic increase in cooling which had been previously enigmatic in eastern U.S. low‐temperature thermochronology datasets. Multi‐stage cooling and exhumation of the NAB is driven by post‐orogenic basin inversion and catchment drainage reorganization, in response to changes in base level due to rifting, plus isostatic and dynamic topographic processes modified by flexure over the long (~200 Myr) post‐orogenic period. This study compliments other regional exhumation data‐sets, while constraining the timing of post‐orogenic cooling and exhumation in the NAB and contributing important insights on the post‐orogenic development and inversion of foreland basins along passive margins.
