“…In the Helanshan, approximately north-south-striking thrust faults offset Archean basement rocks and Paleozoic-Mesozoic strata, and these are correlated to the same fold belt exposed in the Zhuozishan, where a large east-vergent, basement-cored anticline is exposed ( Fig. 1; Darby and Ritts, 2002;Huang et al, 2015). Shortening commencing during the Late Jurassic in the Helanshan and Zhuozishan is based on folded Upper Jurassic and Lower Cretaceous strata in angular unconformity over older Paleozoic-Mesozoic strata (Huang et al, 2015) and Late Jurassic-Early Cretaceous apatite and zircon fission-track ages (Zhao et al, 2007).…”

“…The Middle-Late Jurassic to earliest Cretaceous Yanshanian orogeny of North China (see reviews by Zhang et al, 2008;Dong et al, 2008;Zhang et al, 2014) is recognized from contractional and transpressional fold-andthrust belts in the Tanlu fault zone and North China Plain (Zhang et al, 2015), the Yanshan and western hills of Beijing (e.g., Davis et al, 2001), the ranges bordering the northern and western Ordos Basin (Darby and Ritts, 2007;Davis and Darby, 2010;Huang et al, 2015), and the Taihang-Luliangshan of the central Shanxi Province (this study; Fig. 1).…”

The Middle–Late Jurassic to earliest Cretaceous fold belts of the Yanshanian orogen in North China remain enigmatic with respect to their coeval deformation histories and possible relationship to the contemporaneous Cordilleran-style margin of eastern Asia. We present geological mapping, structural data, and a >400-km-long, strike-perpendicular balanced cross section for the Taihang-Luliangshan fold belt exposed in the late Cenozoic central Shanxi Rift. The northeast-southwest–trending Taihang-Luliangshan fold belt consists of long-wavelength folds (∼35–110 km) with ∼1–9 km of structural relief cored by Archean and Paleoproterozoic metamorphic and igneous basement rocks. The fold belt accommodated ≥11 km of northwest-southeast shortening between the Taihangshan fault, bounding the North China Plain, in the east and the Ordos Basin in the west. Geological mapping in the Xizhoushan, a northeast-southwest–oriented range within the larger Taihangshan mountain belt, reveals two major basement-cored folds: (1) the Xizhou syncline, with an axial trace that extends for ∼100 km and is characterized by a steep to overturned forelimb consistent with a southeast sense of vergence, and (2) the Hutuo River anticline, which exposes Archean–Paleoproterozoic rocks in its core that are unconformably overlain by shallowly dipping (<∼20°) Lower Paleozoic rocks. In the Luliangshan, Mesozoic structures include the Luliang anticline, the largest recognized anticline in the region, the Ningjing syncline, which preserves a complete section of Paleozoic to Upper Jurassic strata, and the Wuzhai anticline; together, these folds are characterized by a wavelength of ∼45–50 km. Shortening in the Taihang-Luliangshan fold belt is estimated to have occurred between ca. 160 Ma and 135 Ma, based on the age of the youngest deformed Upper Jurassic rocks in the Ningjing syncline, previously published low-temperature thermochronology, and regional correlations to better-studied Yanshanian fold belts. The timing of basement-involved deformation in the Taihang-Luliangshan fold belt, which formed >1000 km from the nearest plate margin, corresponds with the termination of arc magmatism along the eastern margin of Asia, implying a potential linkage to the kinematics of the westward-subducting Izanagi (paleo-Pacific) plate.

“…1). The west side of Yinchuan basin is connected with the Helanshan intracontinental superimposed deformation belt (Huang et al 2015) via the Helanshan eastern piedmont fault (F 2 ). On the eastern side, the Yinchuan basin is bounded by Huanghe fault (F 5 ), which separates the Yinchuan basin from the Ordos block.…”

The Yinchuan basin, located on the western margin of the Ordos block, has the characteristics of an active continental rift. A NW-striking deep seismic reflection profile across the center of Yinchuan basin precisely revealed the fine structure of the crust. The images showed that the crust in the Yinchuan basin was characterized by vertical stratifications along a detachment located at a two-way travel time (TWT) of 8.0 s. The most outstanding feature of this seismic profile was the almost flat Mohorovičić discontinuity (Moho) and a high-reflection zone in the lower crust. This sub-horizontal Moho conflicts with the general assumption of an uplifted Moho under sedimentary basins and continental rifts, and may indicate the action of different processes at depth during the evolution of sedimentary basins or rifts. We present a possible interpretation of these deep processes and the sub-horizontal Moho. The high-reflection zone, which consists of sheets of high-density, mantlederived materials, may have compensated for crustal thinning in the Yinchuan basin, leading to the formation of a sub-horizontal Moho. These high-density materials may have been emplaced by underplating with mantlesourced magma.

“…The North China Block, in eastern Asia, is mechanically and dynamically complex with three active boundaries, including a western paleo‐Pacific subduction zone along the eastern margin of the continent, a subduction/collisional zone between the Qiangtang and Lhasa blocks in what is now Tibet, and a suture between the Siberian plate and North China Block to the north (Figure ; Cheng et al, ; Li et al, ). The western Ordos Basin (WOB), in the western North China Block, is an excellent example for studying the Mesozoic intraplate deformation associated with the faraway contemporaneous subduction and collisional zones that bordered Mesozoic Asia (e.g., Darby & Ritts, ; Huang, Shi, Chen, & Li, ; Liu & Yang, ; Ritts, Weislogel, Graham, & Darby, ; Zhang, Li, Li, Qi, & Zhang, ; Zhang et al, ).…”

Detrital zircon geochronology of the Jurassic strata in the western Ordos Basin, North China: Constraints on the provenance and its tectonic implication

et al. 2017

U–Pb detrital zircon data from the Jurassic strata in the western Ordos Basin (WOB) show significant age differences between formations, from lower to upper including the Yan'an, Zhiluo, Anding, and Fenfanghe formations. The main peaks in the detrital zircon age spectra of the Yan'an Formation are at ca. 245, 444, 1813, and 2,387 Ma, which resemble those of the underlying Triassic strata in the WOB. Combined with the occurrence of reworked sporopollen and carbonate debris, the sediments of the Yan'an Formation are interpreted to be potentially recycled from the residual Triassic highlands. The overlying Zhiluo Formation contains detrital zircons mostly in the 260–290 Ma age range with only one peak at 269 Ma, reflecting primary derivations from the Permian granites in the Yinshan Belt to the north and/or the Alxa Block to the northwest. The detrital zircon age compositions of the Anding Formation, however, are most varied, with one prominent age peak at 274 Ma and several other minor peaks at 348 Ma, 447, 932, 1641, 2143, and 2514 Ma, reflecting complex origins. The uppermost syntectonic Fenfanghe Formation, contains detrital zircons with similar age compositions with the Yan'an Formation, once again interpreted as the result of recycled sedimentation. These two phases of multicycle sedimentation in the WOB reveals two intense tectonic events in the Late Triassic and Late Jurassic, whereas the provenance transition between the Yan'an and Zhiluo formations implies a less intense but extensive event in the Middle Jurassic. The complex age composition of the Anding Formation, however, are possibly as the result of climate change corresponding to the change of petrology and sediment colour. These Early‐Middle Mesozoic tectonic events evidenced by the U–Pb ages record the tectonic transition of the North China Block from the Tethys to the paleo‐Pacific tectonic domains.
