“…All the 166 grains analyzed by electron microprobe are essentially fluorapatite with Cl concentrations ranging between ~0.0 and 0.5 wt % (Figure c). This is consistent with the relative low mean D par (diameter of etch figures parallels to the crystallographic c axis) value from the source area rocks in either the Great Xing'an Range (1.5 ± 0.2–2.4 ± 0.3 μm) (Li et al, ) or the Lesser Xing'an Range (1.4 ± 0.2–2.0 ± 0.2 μm) (Li & Gong, ), which form the major western and northern margins of the basin.…”

“…Specifically, the values of MTL in the central downwarp (from 11.08 μm to 11.84 μm) are all less than 12 μm, shorter than those of the peripheral uplift zone (from 11.69 μm to 12.91 μm). These track lengths are evidently smaller than both the standard, unannealed MTL of 16.3 ± 0.9 μm (Gleadow et al, ) and the MTL (12.3–13.3 μm) of major provenance Great Xing'an Range with a standard deviation of ~2.0 μm (Li et al, ).…”

“…To attain these goals, first, we provide a direct comparison of the AFT age pattern and cooling phases of the thermal histories (t‐T paths) with the major post‐rift unconformities. As a next step, we made a comprehensive review of the recently published apatite and zircon fission track data from the broader region encompassing the Songliao Block (Chen, ; Deng et al, ; Li & Gong, ; Li et al, ; Sun et al, ; Wu, Zhang, et al, ). Afterward, we place identified uplift and exhumation events in the context of regional tectonics (Braun, ), thus deciphering the major orogenic pulses in the northeastern Chinese section of the Asian continental margin.…”

Post‐rift Tectonic History of the Songliao Basin, NE China: Cooling Events and Post‐rift Unconformities Driven by Orogenic Pulses From Plate Boundaries

et al. 2018

The classic lithosphere‐stretching model predicts that the post‐rift evolution of extensional basin should be exclusively controlled by decaying thermal subsidence. However, the stratigraphy of the Songliao Basin in northeastern China shows that the post‐rift evolution was punctuated by multiple episodes of uplift and exhumation events, commonly attributed to the response to regional tectonic events, including the far‐field compression from plate margins. Three prominent tectonostratigraphic post‐rift unconformities are recognized in the Late Cretaceous strata of the basin: T11, T03, and T02. The subsequent Cenozoic history is less constrained due to the incomplete record of younger deposits. In this paper, we utilize detrital apatite fission track (AFT) thermochronology to unravel the enigmatic timing and origin of post‐rift unconformities. Relating the AFT results to the unconformities and other geological data, we conclude that in the post‐rift stage, the basin experienced a multiepisodic tectonic evolution with four distinct cooling and exhumation events. The thermal history and age pattern document the timing of the unconformities in the Cretaceous succession: the T11 unconformity at ~88–86 Ma, the T03 unconformity at ~79–75 Ma, and the T02 unconformity at ~65–50 Ma. A previously unrecognized Oligocene unconformity is also defined by a ~32–24 Ma cooling event. Tectonically, all the cooling episodes were regional, controlled by plate boundary stresses. We propose that Pacific dynamics influenced the wider part of eastern Asia during the Late Cretaceous until Cenozoic, whereas the far‐field effects of the Neo‐Tethys subduction and collision processes became another tectonic driver in the later Cenozoic.

“…The slab rollback of the subducted Palaeo-Pacific plate most likely activated a large-scale upwelling of the asthenosphere and a back-arc spreading along the entire margin of northeastern China, softening the lithosphere and thereby facilitating the lithosphere thinning observed across the East Asian continental margin in the Early Cretaceous, triggering the widespread SSW extension characterized by extensive rifting and multiple episodes of volcanism. Li et al (2011) suggest that the rapid magmatism began to slow during the Late Cretaceous, but that magmatic activity still continued with an upwelling asthenosphere. This model is compatible with the occurrence of the intercontinental orogeny of the Daxingan Mountains and the magmatic activities closely related to the Pacific plate subduction (Lin et al 1998;Ge et al 1999;Deng et al 2004;Lei & Zhao 2005;Shao et al 2005;Wu et al 2005a;2005b).…”

Fracture modelling based on the stochastic extended finite element method

Because a large number of oil and gas reservoirs are naturally fractured, they play an important role in hydrocarbon exploration and production. To fully extract and model the fracture system features of reservoirs, a new fracture modelling method, called the stochastic extended finite element (SEFE) method, is presented in this paper. This method couples fracture mechanics and the kriging method with a multi-field trend in an attempt to benefit from the advantages of each method: compliance with fracture mechanics equations and the reproduction of the fracture’s observed data, respectively. Based on the SEFE simulation method, we wrote a fracture modelling system software and built a fracture propagation model and a fracture distribution model of the Upper Cretaceous Formation in the Daqingzi region. A parallel study was performed to verify the fracture propagation pattern and boundary conditions in the proposed model based on a geomechanical analogue experiment. The results of these studies demonstrate that fracture modelling based on the SEFE method may improve the precise characterization of fractured reservoirs.

Apatite fission-track (AFT) tests of clastic samples from the Greater Khingan Mountains (GKM) in China show a center age of 260-62 Ma. Thermal modeling of observed fission-track-length distributions shows three stages of rapid cooling that may have been caused by extensions between 130 and 94 Ma, 30 and 15.3 Ma, and 45 and 0 Ma, and a heating event that may have been caused in part by changes in the subduction direction of the Pacific plate between 64 and 45 Ma. The cumulative exhumation since the Early Cretaceous, is approximately 3 km. The steady-state terrain model in the three-dimensional numerical simulation is highly consistent with the time and rate of the two-dimensional thermal history simulation for the Early Cretaceous exhumation event. The cooling age clusters of ˜160 to 100 Ma are similar in the GKM and Hailar-Erlian Basins.This correlation provides a basin-mountain link for the two tectonic domains. Such a basin-mountain coupling lasted through 100-42 Ma, as supported again by the shared cooling ages of samples from the GKM and detritus from the range-bounded basins on the two sides of the mountain range. We interpreted the 130-94 Ma cooling event recorded in the GKM as a result of crustal thickening in response to the closure of the Mongolia-Okhotsk Ocean. An increase in the subduction velocity of the Pacific plate since ca. 45 Ma may have created a post-arc extensional tectonic setting that has prevailed to the present in the GKM.
