“…Considering the depositional setting, paleo‐flows with east or west directions are interpreted as basin axial flows that ran along the basin depocenter (cf. Cope et al, ; Liu, Kuang, et al, ). In the J 3 ‐K 1 3 unit alluvial fan deposits, the paleocurrents are mostly south directed.…”

Late Jurassic‐Early Cretaceous Deformation in the Western Yanshan Fold‐Thrust Belt: Insights From Syntectonic Sedimentation in the Chicheng Basin, North China

The Yanshan fold‐thrust belt is a significant intraplate deformation belt along the northern margin of North China Craton and records multiple phases of deformation during the Mesozoic. However, the specific tectonic evolution of the Yanshan belt during the Mesozoic has long been debated. In particular, many arguments exit regarding whether a contractional or extensional context dominated the Yanshan belt in the Late Jurassic‐Early Cretaceous. One reason for this argument is the poor understanding of the tectono‐sedimentary relationship preserved in the sedimentary records. A lack of evidence of syntectonic sediments makes it more difficult to reconstruct this relationship. The Chicheng basin in the western Yanshan belt contains complete Upper Jurassic‐Lower Cretaceous succession and is bounded by marginal faults. New regional geological mapping, detailed sedimentary facies analysis, and recognition of two growth strata packages help reconstruct the tectono‐sedimentary relationship in the Chicheng basin. Additionally, zircon U‐Pb dating provides constraints on the timing of the deformation. Our results suggest that the dynamic sediment dispersal system in the Chicheng basin during the Late Jurassic‐Early Cretaceous were controlled by two phases of thrusting, including the activities of the Shangyi‐Pingquan fault during 162–147 Ma, and the Fengning‐Longhua fault during 140–135 Ma. Therefore, we propose that the western Yanshan belt was in a contractional context during the Late Jurassic‐Early Cretaceous. Our findings indicate that the tectonic setting of the Yanshan belt experienced a prominent transition from E‐W trending structures to NE‐SW trending structures and that this transition was probably related to subduction of the Paleo‐Pacific plate beneath the East Asian continent.

“…The Qaidam Basin is the largest high‐altitude terrestrial basin in the north‐eastern Tibetan Plateau and an important hydrocarbon exploration base of the north‐west China's Jurassic coal measures (Cao et al, ; Jian, Guan, Zhang, & Feng, ; Liu et al, ; Figure ). Including Qaidam Basin, exceptionally thick Jurassic sedimentary successions occur widely throughout Mesozoic terrestrial basins in north‐west China (Jian et al, ; Li, Yu, Tan, et al, ; Liu et al, ). This succession preserves detailed evidence of the Mesozoic tectonic and climatic history of the Qaidam Basin and related regions.…”

The Jurassic sequence in the northern Qaidam Basin can be represented by the lower coal‐bearing swamp‐lacustrine sediments unit and the upper reddish clastic deposits suite, which recorded dramatic transition of deposit environment changes. Whole‐rock geochemical data of this succession in Dameigou profile were used to reconstruct the provenance and chemical weathering history. Based on the major element discrimination diagrams, trace element ratios and chondritenormalized REE patterns, most sediments were derived from a similar source area with felsic‐intermediate rocks as dominant contributors. Multiple geochemical parameters and index displayed good correlation, via vertical variations sequence, Jurassic chemical weathering history of northern Qaidam Basin was established, and four stages were recognized from the profile. Phases I and III experienced intense chemical weathering, while Phases II and IV are characterized by mild to moderate chemical weathering. Based on this, long‐term Jurassic climatic evolution of the Qaidam Basin was reconstructed. Early‐middle period of Early Jurassic and middle period of Middle Jurassic developed warm and humid climate. On the contrary, late Early Jurassic‐early Middle Jurassic and late Middle Jurassic‐Late Jurassic was deposited under relatively semiarid to arid climatic conditions.

“…Zhang et al () demonstrated that the tectonics in NCC changed from compression during the Early Triassic to extension during the Late Triassic‐Early Jurassic, and such a transition provided a favorable condition for the thermal event. Based on the Mesozoic basin and its palaeogeographic evolution in North China, Liu et al () divided the Mesozoic tectonic evolution into five stages: (a) the Early‐Middle Triassic; (b) the Late Triassic to Early‐Middle Jurassic; (c) the Late Jurassic to earliest Early Cretaceous; (d) the middle‐late Early Cretaceous; and (e) the Late Cretaceous. During the Early‐Middle Triassic (Stage 1), the Xingmeng Orogenic Belt (XMOB, i.e., eastern part of Central Asia Orogenic Belt, CAO, shown in Figure b) of northern North China was settled into the tectonic transition from syn‐orogenic compression to postorogenic extension with intensive uplifting.…”

Late Triassic‐Early Jurassic abnormal thermal event constrained by zircon fission track dating and vitrinite reflectance in Xishan coalfield, Qinshui Basin, central North China

Xishan coalfield, Shanxi, is located in the northwest of the Qinshui Basin, central North China. It is notable for its varieties of coal rank ranging from high volatile bituminous coals to anthracite as well as having abundant coalbed methane resources. Zircon fission track (ZFT) analyses were carried out on the zircons in 2 Upper Carboniferous and 5 Lower‐Middle Permian sandstones, and vitrinite reflectance of Late Carboniferous and Early Permian coals were measured to determine the timing of thermal events and maximum paleo‐temperatures, which were responsible for coal maturation and coalbed methane generation. Maximum paleo‐temperatures calculated from vitrinite reflectance values reached to about 232 and 223 °C in Late Carboniferous and Early Permian coals, respectively, and the estimated paleo‐temperature gradient was 11.84 °C/100 m, representing an intensive abnormal thermal event. Results of the ZFT dating indicated that 5 samples failed the χ2‐test and 2 samples passed the test. The decomposition results of the 5 samples divided their age populations into 3 periods: (a) older ages (537, 584, and 802 Ma) than sandstones ages, (b) close to or slightly older than their depositional ages (289, 301, and 331 Ma), and (c) younger than the depositional ages (181–215). The 2 samples that passed χ2‐test yield the central ages of 168 ± 7 Ma and 190 ± 8 Ma, respectively, younger than the deposition age. The close to or older ages than the sandstones depositional ages represent the tectonothermal events occurring in their source areas; the younger ages indicate the existence of the postdepositional tectonothermal event. The agreement of the partly annealing temperature zone (210–300 °C) of zircon fission tracks with the calculated maximum paleo‐temperatures from vitrinite reflectance suggests a Late Triassic‐Early Jurassic abnormal thermal event with the formation time of the present coal rank being 181–215 Ma, rather than a unique intrusion at 95–135 Ma on the western margin of coalfield as previously believed. Combined with other ZFT ages regionally, this abnormal event also occurred in the southern as well as the northern parts of the Qinshui Basin. The Late Triassic‐Early Jurassic intensive extension in the North China Craton is the geodynamic setting of this tectonothermal event.
