in this study, the quaternary deformation and tectonic activity of saeedabad-chai drainage basin, are assessed using geomorphic approach. this drainage basin is located in northern slope of sahand mountain. north tabriz fault (ntf), is passing from the saeedabad-chai basin. variation in the morphology of mountain front provied the basis for geomorphic assessment of tectonic activity. therefore,...
Erosion, sediment production, and routing on a tectonically active continental margin reflect both tectonic and climatic processes; partitioning the relative importance of these processes remains controversial. Gulf of Alaska contains a preserved sedimentary record of the Yakutat Terrane collision with North America. Because tectonic convergence in the coastal St. Elias orogen has been roughly ...
current research in order to identify neo tectonic activity of the ziyarat basin has been made on the northern slopes of the eastern alborz in south-gorgan and using the index of morpho tectonic and tectonic evidence in the area. in this regard, the 6 morphological parameters were calculated and the results are analyzed. the overall results of these features, as indicators of the relative activ...
The Puqu Fault is situated in Southern Tibet. It is influenced by the eastward extrusion of Northern Tibet and carries the clockwise rotation followed by the southward extrusion. Thus, the Puqu Fault is bounded by the principal dynamic zones and the tectonic evolution remains active alongside. This study intends to understand the tectonic activity in the Puqu Fault Region from the river profile...
Tectonic geomorphology is part of Earth Sciences, which deal with study of the interaction of tectonic and geomorphology. In other words it studies the effective tectonic processes in forming and changing the landforms. Geomorphic and morphometric indicators are suitable tools to the morphotectonic analysis for different areas. These indicators are used as the base tool to identify and recognit...
abstract tectonic, plays a key role in the evolution of morphology and can be distinguished with morphotectonic, rivers and structural parameters. an analysis of morphometric parameters illustrates that the development of them is associated with faults activities and rocks resistance. morphotectonic analysis also supplies seismotectonic setting for a region. for appropriate and survey tectonic ...
Structural and tectonic evolution of the Umm Gheig/ El-Shush region, central Eastern Desert of Egypt
The rocks of the Wadi Umm Gheig/El-Shush area in the central Eastern Desert of Egypt form part of the Nubian Shield, a component of the Neoproterozoic Pan-African Orogeny. The rocks have been divided into three units: (i) low-grade metamorphosed rocks, which consist of metavolcanic rocks interleaved with slices of ophiolitic melange; (ii) high-grade metamorphic rocks, which consist of syn-tecto...
Earth's surface archives the combined history of tectonics and erosion, which tend to roughen landscapes, and sediment transport and deposition, which smooth them. We analyzed hillslope morphology in the tectonically active Dragon's Back Pressure Ridge in California, United States, to assess whether tectonic uplift history can be reconstructed using measurable attributes of hillslope features w...
