“…However, thrusting and sinistral strike-slip there began later, at approximately 5.4 Ma and 2.6 Ma, respectively (Wang et al, 2013b). The maximum horizontal displacement was 3.2 km, while the average slip rate during the late Quaternary was 2.29-2.86 mm/a (Chai et al, 1998;Li, 2005).…”

“…Many studies have been conducted on the extension and deformation of this arc tectonic belt during the late Cenozoic IGCEA et al, 1990;Zhang et al,1988Zhang et al, , 1990Zhang et al, , 1991Chai et al, 1998;Zheng et al, 2006;Li et al, 2009;Zheng et al, 2009, 2013b; Wang et al, 2013bWang et al, , 2014Shi et al, 2013;Zhang et al, 2015). These studies focused mostly on the Haiyuan fault and Tianjingshan fault, however, few studies have been conducted on the outermost SGK-NSSF, and these have been limited to indirect inferences of its evolutionary processes from the interpretations of seismic profiles (Wang et al, 2013a;Chen et al, 2013).…”

The kinematic characteristics of the Sanguankou-Niushoushan fault (SGK-NSSF) are of great significance to the understanding of the extension of the arc tectonic belt in the northeastern margin of the Tibet Plateau. Using field surveys and various data collection methods, including large-scale geological mapping, measurement of typical topographies, and dating of sedimentary strata, it was determined that the SGK-NSSF exhibits obvious dextral strike-slip characteristics and thus is not a sinistral strike-slip fault, as believed by previous researchers. The results of this study show that the geological boundaries for the Paleozoic, Mesozoic, and Cenozoic eras were all dextrally dislocated by the fault, with the faulted displacements being similar. The maximum strike-slip displacement of the fault, after elimination of topographic effects, was found to be 961±6 m. The Sanguankou fault at the northern section exhibits obvious characteristics of more recent activities, with a series of small gullies having undergone synchronized dextral writhing after traversing the fault. The average horizontal slip rate of the fault since the late Quaternary was determined to be approximately 0.35 mm/a. The pre-existing fold structures formed during the late Pliocene were dislocated by the fault and became ex situ, indicating that dextral strike-slip of the fault could not have occurred prior to the late Pliocene. The maximum displacements and average slip rates were used to estimate the onset time of the dextral strike-slip activities of the fault as being after 2.7 Ma. In this study, the understanding of previous researchers concerning the extension in the northeastern margin of the Tibet Plateau was combined with analyses of the successive relationships between fold deformations and fault activities. This led to the finding that the extension in the northeastern margin of the Tibet Plateau reached the vicinity of the SGK-NSSF during the late Pliocene (~2.7 Ma), causing regional uplift and fold deformations of the strata there. During the early Quaternary, the northeastern compression of the Tibet Plateau and the counterclockwise rotation of the Ordos block collectively resulted in the dextral strike-slip activities of the SGK-NSSF. This then formed the foremost margin of the arc tectonic belt extension in the northeastern margin of the Tibet Plateau.

“…Given the wider geological history of the region, the facies association must bare the imprint of environmental events and changing sediment supply sources related to tectonic controls and associated relief generation (see for example, Lin et al 2010Lin et al , 2011. Similarly, the appearance of coarser sediments, sandstones, and gravel may be the response to either uplift phases of the Liupan Shan Lin et al 2010Lin et al , 2011Wang et al 2011Wang et al , 2013 providing coarser sediments, or a possible change in hydrology and sediment supply linked to climate events (or some combination of the two).…”

“…The area is dominated by a series of ranges and intermontane basins, with uplift having occurred during the late Cretaceous and again in the late Cenozoic, associated with the northward progression of the Tibetan Plateau (Tapponnier et al 2001;Wang et al 2013). Zhang et al (1991) originally advanced the view that Cenozoic uplift in the area did not occur until the Pliocene, but this claim has been revised, and it is now recognised that the uplift history of the area extends back to the Miocene (Song et al 2001;Ding et al 2004;Zheng et al 2006;Zhang et al 2006;Lin et al 2009Lin et al , 2010Lin et al , 2011.…”

Most previous studies of the Tibetan Plateau have focused on the processes of crustal thickening and subsequent outward growth. However, lithospheric structure across the tectonic boundaries of the plateau has not yet been fully imaged, and therefore, how geological structures evolved in association with the lateral expansion of the margins remains unclear. Here together with interpretation of regional aeromagnetic anomalies, we employ a recently acquired 165 km long deep seismic reflection image that crosses the northeastern flank of the Tibetan Plateau. The resulting crustal “architecture” suggests that crustal shortening is a primary driver for plateau uplift of northeastern Tibet and that the Xiaoguan Shan to the east of the Liupan Shan belt marks the easternmost edge of the strata that has been affected by the northeastward growth of the plateau. In addition, decoupled crustal deformation owing to differential structural integrity has been accommodated during the subsequent northeastward growth of the plateau.
