Abstract

Theoretical models suggest that active tectonic deformation can impose a primary control on the patterns and styles of channels. The Longmen Shan Fault zone, which is located on the eastern margin of the Tibetan Plateau, has experienced strong tectonic activity, including uplift and strike-slip phases of tectonic movements. Here, we adopt ASTER-GDEM2 data and utilise a stream-power incision model to extract information on the spatial characteristics of differential tectonic movements. Analysis of the patterns and styles of 37 channels exhibits systematic differences in the channel steepness indices and the river sinuosity values along the strike of the Longmen Shan Fault zone. Our primary results demonstrate that the normalised channel steepness indices in the southern part of the Longmen Shan Fault zone are much higher than those in the northern part, where the river sinuosity values are much lower. Comparisons between the five drainage basins reveal that the river systems in the middle southern part of the fault zone are mainly controlled by tectonic uplift and thrusting, whereas the river systems in the middle northern part of the fault zone are mostly attributed to right-lateral strike-slip movement.

龙门山断裂带河流地貌特征及其对区域构造活动的指示意义
理论模型表明,活动构造变形对河道的形态和样式起主要控制作用。龙门山断裂带位于青藏高原东缘,经历了强烈的构造活动,包括隆升和走滑两期构造运动。本文采用ASTER-GDEM2数据,利用流功率切口模型提取差分构造运动空间特征信息。对37条河道形态和样式的分析表明,沿龙门山断裂带走向,河道陡度指数和曲度值存在系统差异。初步结果表明,龙门山断裂带南段河道坡度指数明显高于北段,而北段河道弯度值相对较低。5个流域的对比表明,断裂带中南部的河流系统主要受构造隆升和逆冲作用控制,而断裂带中北部的河流系统主要受右侧走滑运动控制。

期刊介绍: Geodinamica Acta provides an international and interdisciplinary forum for the publication of results of recent research dealing with both internal and external geodynamics. Its aims to promote discussion between the various disciplines that work on the dynamics of the lithosphere and hydrosphere. There are no constraints over themes, provided the main thrust of the paper relates to Earth''s internal and external geodynamics. The Journal encourages the submission of papers in all fields of earth sciences, such as biostratigraphy, geochemistry, geochronology and thermochronology, geohazards and their societal impacts, geomorphology, geophysics, glaciology, igneous and metamorphic petrology, magmatism, marine geology, metamorphism, mineral-deposits and energy resources, mineralogy, orogeny, palaeoclimatology, palaeoecology, paleoceanograpgy, palaeontology, petroleum geology, sedimentology, seismology and earthquakes, stratigraphy, structural geology, surface processes, tectonics (neoteoctonic, plate tectonics, seismo-tectonics, Active tectonics) and volcanism. Geodinamica Acta publishes high quality, peer-reviewed original and timely scientific papers, comprehensive review articles on hot topics of current interest, rapid communications relating to a significant advance in the earth sciences with broad interest, and discussions of papers that have already appeared in recent issues of the journal. Book reviews are also included. Submitted papers must have international appeal and regional implications; they should present work that would be of interest to many different specialists. Geographic coverage is global and work on any part of the world is considered. The Journal also publishes thematic sets of papers on topical aspects of earth sciences or special issues of selected papers from conferences.
