The continental Asia is mainly composed of three major tectonic regimes, the Tethys, Paleo Asian Ocean, and West Pacific. It underwent multi‐stage plate convergences, ocean‐continent transformations, and subductions, collisions and/or collages, and post collisional (orogenic) extensions in Phanerozoic. Tectonic evolution of the Asia brings up a unique fault system and tectonic geomorphological features in the mainland China. Also, it provides a geodynamic background for the formation and evolution of metallogeneses and mineral systems, resulting in nonuniform distribution of tectono‐metallogenic systems and metallogenic belts. The spatiotemporal distribution of mineral deposits in China and adjacent areas exhibits periodic variation under controlling of the full life Wilson cycle and tectonic evolution, forming the plate convergence‐related mineral system in East Asia. Porphyry Cu deposits are mainly related to compressional systems in Paleozoic and early Mesozoic, and more closely related to post‐collision extensional settings in late Mesozoic and Cenozoic. Orogenic Au deposits mainly formed in post‐orogeny extensional setting. Alkaline rock related rare earth element deposits formed mainly at margins of the North China and Yangtze cratons. Granite‐pegmatite Li and other rare metal deposits formed mainly in early Mesozoic, related to Indosinian post‐orogeny extension. Tectono‐metallogenic systems provide important basis for the prospecting of mineral resources. [ABSTRACT FROM AUTHOR]

The Tianshan range, a Paleozoic orogenic belt in Central Asia, has undergone multiple phases of tectonic activities characterized by the N–S compression after the early Mesozoic, including the far‐field effects of the Cenozoic Indian–Asian collision. However, there are limited reports on the tectonic deformation and initiation of Triassic intracontinental deformation in the Tianshan range. Understanding this structural context is crucial for interpreting the early intracontinental deformation history of the Eurasian continent during the early Mesozoic. Growth strata and syn‐tectonic sediments provide a rich source of information on tectonic activities and have been extensively used in the studies of orogenic belts. Based on detail fieldwork conducted in this study, the middle–late Triassic Kelamayi Formation of the northern Kuqa Depression in the southern Tianshan fold‐thrust belt has been identified as the typical syn‐tectonic growth strata. The youngest detrital zircon component in two lithic sandstone samples from the bottom and top of the Kelamayi growth strata yielded U‐Pb ages of 223.4 ± 3.1 and 215.5 ± 2.9 Ma, respectively, indicating that the maximum depositional age of the bottom and top of the Kelamayi growth strata is 226–220 and 218–212 Ma. The geochronological distribution of detrital samples from the Early–Middle Triassic and Late Triassic revealed abrupt changes, suggesting a new source supply resulting from tectonic activation in the Tianshan range. The coupling relationship between the syn‐tectonic sedimentation of the Kelamayi Formation and the South Tianshan fold‐thrust system provides robust evidence that the Triassic intracontinental deformation of the South Tianshan range began at approximately 226–220 Ma (during the Late Triassic) and ended at approximately 218–212 Ma. These findings provide crucial constraints for understanding the intraplate deformation in the Tianshan range during the Triassic. [ABSTRACT FROM AUTHOR]

The North Qilian Shan fold and thrust belt, located at the northern Tibetan Plateau and southern margin of the Hexi Corridor, is a key tectonic unit to decode the formation and expansion of the plateau. Previous studies emphasize the Cenozoic deformation due to the far‐field response to the Indo–Asian collision, but the Mesozoic deformations are poorly constrained in this area. We conducted detailed field mapping, structural analysis, geochronology, and structural interpretation of deep seismic reflectional profiling and magnetotelluric (MT) sounding, to address the superposed results of the Mesozoic and Cenozoic deformation. The results recognized the North Qilian thrust and nappe system (NQTS), the root and the frontal belt are the North Qilian thrust (NQT), and the Yumu Shan klippe (YK), respectively. The middle belt is located between the NQT and the YK. Monzonitic granite zircon U‐Pb dating from the middle belt yields an age of ca. 415 Ma, which is similar to south NQT. The thrusting displacement is estimated at ca. 48 km by structural interpretation of deep profiles. The timing is constrained in the early stage of the Early Cretaceous by the formation of simultaneous growth strata. We suggest that the NQTS has resulted from the far‐field effect of the Lhasa–Qiangtang collision, and the Yumu Shan is uplifted by the superposed Cenozoic deformation. [ABSTRACT FROM AUTHOR]

The late Mesozoic Beishan fold‐thrust belt occupies a key position in central Asia, figuring importantly in our understanding of intracontinental deformation in response to far‐field plate‐boundary forces. To determine when and how the Beishan fold‐thrust belt was developed, we conducted detailed field mapping, structural analysis, and apatite (U–Th)/He (AHe) thermochronology in the Hongliudaquan area, southeastern Beishan Range. The study area exposes the Hongliudaquan fold and thrust system, consisting of the southern Hongliudaquan thrust nappe and autochthonous fold sets. The nappe experienced >16 km northward thrust‐induced translation. The autochthonous fold sets strongly deformed Lower–Middle Jurassic strata showing diverse trends of kilometer‐scale basins and ranges. We interpret that this fold interference pattern was produced in a constrictional deformation field, which underwent synchronous shortening in two orthogonal directions. This stain history was related to synchronous imbricate thrusting, duplex formation, and strike‐slip faulting at different structural levels. Restoration of the Hongliudaquan fold and thrust system yields a minimum of ∼27% (∼10.1 km) north–south shortening strain. Thrusting and nappe emplacement within the Beishan fold‐thrust belt may have started in the late Middle Jurassic and persisted until the Early Cretaceous (∼140–133 Ma). Our AHe data also record ∼124–115 Ma cooling related to footwall exhumation during subsequent normal faulting, indicative of the late Mesozoic intracontinental contraction–extension transition. The Beishan fold‐thrust belt initiated in central Asia via the late Mesozoic reactivation of the Paleozoic–early Mesozoic Beishan orogen as a result of the far‐field responses to multi‐directional plate convergence around Asia. Key Points: The Beishan fold‐thrust belt was formed by contractional deformation in the late Middle Jurassic–Early CretaceousNormal faulting exhumed the footwall rocks at ∼124–115 Ma, indicative of the late Mesozoic contraction–extension transitionIntracontinental shortening in central Asia was driven by far‐field plate convergence around the Asian continent [ABSTRACT FROM AUTHOR]

The migration, accumulation and dispersion of elements caused by tectonic dynamics have always been a focus of attention, and become the basis of tectono‐geochemistry. However, the effects of faulting, especially strike‐slip faulting, on the adjustment of geochemical element distribution, are still not clear. In this paper, we select the West Junggar Orogenic Belt (WJOB), NW China, as a case study to test the migration behavior of elements under tectonic dynamics. The WJOB is dominated by NE‐trending large‐scale sinistral strike‐slip faults such as the Darabut Fault, the Mayile Fault, and the Baerluke Fault, which formed during the intracontinental adjustment under N–S compression during ocean‐continental conversion in the Late Paleozoic. Geochemical maps of 13 elements, Al, W, Sn, Mo, Cu, Pb, Zn, As, Sb, Hg, Fe, Ni, and Au, are analyzed for the effects of faulting and folding on element distribution at the regional scale. The results show that the element distribution in the WJOB is controlled mainly by two mechanisms during tectonic deformation: first is the material transporting mechanism, where the movement of geological units is consistent with the direction of tectonic movement; second is the diffusion mechanism, especially by tectonic pressure dissolution driven by tectonic dynamics, where the migration of elements is approximately perpendicular or opposite to the direction of tectonic movement. We conclude that the adjustment of element distributions has been determined by the combined actions of transporting and diffusion mechanisms, and that the diffusion mechanism plays an important role in the formation of geochemical Au blocks in the WJOB.

Since the traditional direct torque control (DTC) of switched reluctance motors (SRMs) has the shortcomings of large torque ripple and non‐constant switching frequency, this study proposes the deadbeat‐direct torque and flux‐linkage control (DB‐DTFC) method for SRM. By analysing the basic principles of SRM, a discrete‐time model is established to predict the future states of the SRM drive system. With DB‐DTFC, the stator flux and torque can be manipulated during each pulse‐width modulation cycle to minimise torque ripple during operation. As a result, the proposed DB‐DTFC can minimise the torque ripple as well as apply space‐vector modulation with a constant switching frequency. Finally, to verify its effectiveness, DB‐DTFC was applied to the 15 kW three‐phase 12/8‐pole SRM test bench in real time and the results are compared with conventional DTC. [ABSTRACT FROM AUTHOR]
