Abstract Sedimentary deposits in Tibetan Basins archive the spatial‐temporal patterns of deformation and surface uplift processes that created area's high topography during Cenozoic India‐Asia collision. In this study, new stratigraphic investigation Caogou section from Jiuxi Basin northeasternmost part Plateau provides chronologic constraints on northward growth plateau. Magnetostratigraphic analysis results suggest age studied ~1000 m thick spans ~24.2 Ma to 2.8 Ma. Detailed sedimentology...
Abstract The Qilian Shan, at the northeastern frontier of Tibetan Plateau, is a key area for studying expansion mechanism Plateau. Although previous thermochronology and paleomagnetic studies indicate Neogene northward northern there distinct temporal gap in knowledge relative to tectonic history southern Shan. This has hindered complete understanding Cenozoic deformation pattern entire To study growth apatite fission track (AFT) data have been acquired from Zongwulong Shan Huaitoutala...
The northern Tibetan Plateau, north of the Qaidam Basin and south Hexi Corridor (China), consists a series WNW- to NW-trending elongated mountain ranges. Deciphering time-space deformation pattern these ranges is central understanding mechanism plateau formation controversial issue whether Tibet has undergone progressive northward growth or synchronous since India-Eurasia collision. Here, we report new constraints on timing accelerated uplift Tuolai Shan, one in Plateau. New apatite...
Abstract The growth of the Tibetan Plateau is related to Cenozoic India‐Eurasia plate collision; however, its and evolution present margins remain matters debate. Qilian Shan, which located along northeastern margin Plateau, plays a central role in understanding outward plateau. In this paper, we new low‐temperature thermochronologic data from hanging wall Huangcheng‐Shuangta fault (HSF) Lenglongling west region eastern part Shan. Cooling ages thermal history modeling show increased...
Abstract The Cenozoic basins and ranges form the high topography of northeastern Tibet that resulted from India-Eurasia collision. Sedimentary rocks in provide direct insight into exhumation history tectonic processes led to northeastward growth Tibetan Plateau. In this study, we analyzed compared detrital zircon U-Pb ages sands modern rivers draining Bei Shan, North Qilian Shan sandstones Yumen Basin. age distributions indicate strata dated 24.2-16.7 Ma basin were derived provenance changed...
Abstract The development of Cenozoic basins in the northeast margin Tibetan Plateau is central to understanding dynamics plateau growth. Here we present a magnetostratigraphy from Lanzhou Basin, dating terrestrial deposits Eocene (~47 Ma) middle Miocene (~15 Ma). stratigraphic observation, palocurrent, and sediment provenance analysis suggest that Basin (subbasin Longzhong Basin) probably initiated as topographically enclosed depression during early Oligocene (~47–30 We suspect right‐lateral...
Abstract The left‐lateral strike‐slip Altyn Tagh fault that defines the northern margin of Tibetan Plateau plays a crucial role in accommodating Cenozoic deformation related to growth plateau. However, slip history along remains highly debated. Here we report new 14–16 Ma apatite fission track (AFT) and 9–11 (U‐Th)/He (AHe) data western Danghenan Shan, north Tibet. Age‐elevation relationships AFT/AHe age differences suggest period rapid exhumation with an average rate 0.1–0.3 km/Ma from 16 9...
High-precision and high-resolution topography is the basis of quantitative study active faults. Light detection ranging (lidar) currently most popular method for obtaining such data, but its relatively high cost greatly limits use in many geoscience applications. Recently, with rapid development computer vision science growing application small unmanned aerial vehicles (UAVs), Structure from Motion (SfM) photogrammetry shows great potential providing topographic information comparable...
Abstract Reported magnitudes ranging between 7.8 and 8.7 highlight a confusion about the true size of 1920 Haiyuan earthquake, largest earthquake recorded in northeast Tibetan Plateau. We compiled global data set previously unlooked‐at historical seismograms performed modern computational analyses on digitized seismic records. found epicenter to be near town obtained moment magnitude M W =7.9±0.2 . Following traditional approaches, we m B =7.9±0.3 with from 21 stations S (20)=8.1±0.2 three...
Abstract Spatial and temporal patterns of mountain building in the northeastern Tibetan Plateau provide important constraints on competing plateau growth models. We focus East Kunlun Shan (EKLS), where timing Cenozoic deformation remains controversial. Seven apatite (U‐Th)/He samples were collected around a tilted erosion surface middle segment EKLS. A break slope at ∼25 Ma is identified along paleodepth below surface, which we interpret to represent onset thrust faulting northern margins...
Abstract The Cenozoic Asian climate system experienced a transformation from zonal pattern to monsoon-dominant around the Paleogene-Neogene boundary. A series of dynamic mechanisms, such as uplift Tibetan Plateau, retreat Paratethys Sea, expansion South China and decreasing atmospheric CO2 content, has been suggested be responsible for pattern. However, role topographic growth in eastern rarely considered. As natural divides geography, climate, biology, two most distinct sets relief China,...
Abstract The Maidan fault, which is an east‐northeast trending fault in the southwestern Tian Shan, a sinistral reverse that extends more than 400 km length and constitutes boundary between Shan Tarim Basin. Here we quantify its late Quaternary activity based on interpretations of high‐resolution remote sensing images detailed field investigations. In Aheqi valley, ~150‐km‐long active can be divided into northeastern segments variations strike geometry. Based analysis offset geomorphological...
Abstract The roles of lower‐crustal flow and upper‐crustal shortening on the growth SE Tibetan Plateau remain under debate, which calls for a knowledge about regional exhumation history. We analyzed apatite fission track ages modern sediments from both east west sub‐catchments along Anninghe River, in plateau. obtained four age components, with peaks bit younger than west. Combing asymmetric topography higher relief east, we concluded non‐uniform pattern. components are at Oligocene,...
The Yabrai range-front fault accommodates deformation within the middle Gobi Alashan block between Tibetan Plateau and Ordos block. As such, it provides opportunity to examine transition contractional associated with growth of extensional across North China. Geomorphic mapping active trace trench investigations reveal that is composed three segments varying strike, but for which sense motion, scarp height, slip history appear be kinematically compatible along fault. Displaced Holocene late...
Discrepancies between geological, seismic and geodetic rates of strain can indicate that crustal deformation, hence hazard, are varying through time. Previous studies in the northern Shanxi Grabens, at northeastern corner Ordos Plateau China, have found extension anywhere 0 6 mm a−1 an azimuth 95° 180°. In this paper we determine across Grabens from offset geomorphological features a variety Quaternary dating techniques (including new IRSL Ar-Ar ages), Kostrov summation using 700 yr...
Abstract Reconstruction of the along‐fault slip distribution provides an insight into long‐term rupture patterns a fault, thereby enabling more accurate assessment its future behavior. The increasing wealth high‐resolution topographic data, such as Light Detection and Ranging photogrammetric digital elevation models, allows us to better constrain distribution, thus greatly improving our understanding fault South Heli Shan Fault is major active on northeastern margin Tibetan Plateau. In this...
