stream profile analysis Tectonic Geomorphology and neoTectonic activity of the damxung yangbajain rift in the south tibetan plateau
Earth Surface Processes and Landforms, 2016Co-Authors: Wenliang Jiang, Zhujun Han, Jingfa Zhang, Qisong JiaoAbstract:The Damxung-Yangbajain rift is one of the most active north–south trending rifts in the south Tibetan Plateau, and it has been playing an important role in accommodating the east–west extension of the Tibetan Plateau. Both stream profiles on the Nyainqentanglha Range adjacent to the northwest part of the Damxung-Yangbajain rift and Tectonic Geomorphology in the north of the rift are analyzed to assess the spatial pattern and intensity of rock uplift which is related to neoTectonic activity. A total of 85 stream profiles across the Nyainqentanglha Range are analyzed, and 111 knickpoints are interpreted. Most of these stream profiles are characterized by prominent convexities with two or more knickpoints, many of which are formed due to the strong rock uplift evidenced by abnormal concavity and extremely high steepness indices during the Quaternary. NeoTectonic activity in this region is well replicated in the stream profile indices and offset landforms. Tectono-geomorphic analysis shows that the concavity and steepness indices correlate with the fault movements at many places. The Damxung-Yangbajain rift is characterized by left-lateral strike-slip in the north of Damxung and by normal movement in middle and southern parts. The middle and southern parts have been undergoing higher uplift than has the northern area. It is most likely that the strong uplift is related to the heat flow under the crust. Earthquakes occurring in the Damxung-Yangbajain rift, including a M8 in 1411 and M6.6 in 2008, are thought to be related to heat flow activity. All of the stream profile indices and Tectonic Geomorphology show that the Damxung-Yangbajain rift is not in a stable state. Copyright © 2016 John Wiley & Sons, Ltd.

Tectonic Geomorphology of the northern Upper Rhine Graben, Germany.
Global and Planetary Change, 2007Co-Authors: Gwendolyn Peters, Ronald T. Van BalenAbstract:Abstract This paper focuses on the northern Upper Rhine Graben (URG), which experienced low Tectonic deformation and multiple climate changes during Quaternary times. Recently, human modifications have been high. The paper presents the results of a study into the effects of fault activity on the landscape evolution of the area. The study aims to detect active faults and to determine the last phase of Tectonic activity. Information on the long-term Tectonic activity is gained from the geological record (drainage system, sediment distributions, fluvial terraces, fault mapping). Previous studies are reviewed and supplemented with new data on Tectonic activity. The compilation of all data is presented as a series of paleogeographic maps from Late Miocene to present. It is demonstrated that differential uplift of the western margin of the northern URG had significant impact on the drainage system, the formation of fluvial terraces and the landscape of the western graben shoulder. In a second part of the paper, the imprint of Tectonics on the present-day landscape is investigated at the regional scale in order to determine the location of fault scarps and Tectonically influenced parts of the drainage system. This study uses an integrated analysis of topography, drainage patterns and fault network. The comparison of features suggests a structural control by numerous NNE- and NNW-oriented intra-graben faults on the flow directions of streams in the Rhine Valley. Several scarps in the Rhine Valley are identified and interpreted to result from intra-graben faulting activity, which in turn controlled fluvial dissection. The third part of the paper presents quantitative measurements of the present-day landscape shape. Calculations of geomorphic indices are used to determine the balance between erosional and Tectonic processes and to identify active fault segments. The mountain-front sinuosity and valley shape indices measured along the border faults and in the footwall area are used to determine the level of activity of the faults. Stream profiles of the western and eastern catchments of the River Rhine are investigated for gradient changes at the crossing of the border faults. The combined interpretation of geomorphic indices points to active border fault segments on both sides of the graben. Based on the integration of all results it is concluded that the Tectonic morphology identified for the northern URG formed in response to long-term, low level Tectonic processes. Due to a significant decrease in erosional and depositional activity during the last 15,000 years, the Tectonic morphology has probably been preserved until present.
