Mapping of Planation surfaces in the southwest region of Hubei Province, China—Using the DEM-derived painted relief model
Journal of Earth Science, 2012Co-Authors: Hui Li, Xuya Huang, Qinglu Deng, Timothy M KuskyAbstract:Planation surfaces (PS) play a major role in reconstruction of the evolutionary history of landforms in local areas. Thus, objective and consistent mapping of Planation surfaces from remotely sensed data (e.g., satellite imagery, digital elevation models (DEMs)) is paramount for interpreting the geomorphological evolution. Due to the lack of dated sedimentary covers and the difficulties of comprehensive field work, the number and age of Planation surfaces in the Southwest Hubei (湖北) Province of China are still controversial. In order to map the PS in the study area, four data visualization techniques including ETM+ false color composite, grey-scale DEM, shaded relief model (SRM) and painted relief model (PRM) were examined. It is found that the PRM is the most optimal technique for Planation surface mapping. The study area was successfully mapped by visual interpretation of a PRM derived from ASTER GDEM. The mapped PS was divided into five classes in terms of elevation according to previous studies, varying from 1 700–2 000 (PS1), 1 300–1 500 (PS2), 1 000–1 200 (PS3), 800–900 (PS4) to 500–600 (PS5) m. The results were partially compared with the published works. It is revealed that this method of mapping enjoys a higher accuracy and can reduce the time and effort required in the traditional mapping to a large extent. The results also demonstrated that the PRM is an effective tool for geomorphological feature mapping with considerable accuracy. The preliminary results can serve to facilitate locating representative samples for the Planation surfaces dating, thus to determine the ages of PS in the study areas.

Planation surfaces of the Tian Shan Range (Central Asia): Insight on several 100 million years of topographic evolution
Journal of Asian Earth Sciences, 2019Co-Authors: Julien Morin, Marc Jolivet, Laurie Barrier, Amandine Laborde, Olivier DauteuilAbstract:In Central Asia, numerous fragments of Planation surfaces are visible within the present day topography. However, their precise timing of formations is still poorly constrained and it is not clear if they are remnants of a single extensive Planation surface or if they represent different Planation episodes. By reconstructing the landscape evolution of the Tian Shan region and by analyzing the relations between the Planation surfaces preserved within the eastern Tarim Basin and the sedimentary record, we demonstrate that the numerous erosional surfaces preserved within the Tian Shan Range represent different episodes of surfaces genesis. These erosion events span from the late Paleozoic to the Early Cenozoic. The widespread preservation of large fragments of these surfaces within the Tian Shan Range implies that this region did not undergo strong relief building during most of its Mesozoic evolution but was dominated by plains associated to small hills along episodically active discrete tectonic structures. Finally, the preservation of these surfaces within the active Tian Shan Range implies a long-term, strong non-equilibrium state of the topography during its Cenozoic evolution. This was probably promoted by the arid to semi-arid climate prevailing since the Late Paleogene onset of relief building.
