عنوان انگلیسی Quantitative analysis of the impact of neo tectonic activity the index on morpho tectonic in the catchment ziyarat
چکیده انگلیسی مقاله 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 activity was calculated and it consists of four classes of active regions, active regions with moderate to low activity, were classified into. Often the high activity of the class was made east and south-east basin ziyarat, while other areas of middle class are. The results of this study, low amounts calculated mountain front sinuosity and high is the stream–gradient index. Increased activity the tectonics region in the basin can be relative to position of the peak stream- gradient along the faults and the segment of faults. The drainage basin asymmetry of many sub basins is estimated more or less 50, that is shown the diversion to the west or east of the drainage basin. On the other hand, high levels of drainage basin asymmetry visit the main branch of the river and the Caspian fault clearly: in the southern and south eastern of this basin is affected by activity Radkan and Tal Anbar faults. The results of the evaluation of the relative active tectonics index, represents the activity of the focus areas in the central and south made the ziyarat to the eastern basin, while other areas of middle class of the relative active tectonics, this confirms the activation of the neo tectonics area that is. Studies on the fracture process, works and drainage fault in the northern and central station is indicating, the close association between the lineaments, the structural elements and the geometric relationships between them and the position of waterfalls and fountains there.
