Abstract:   (2533 Views)
Introduction and Background: Murghab river is one of the main streams of Zayandeh river. No significant Neotectonic studies have been conducted in the basin of this river, but the passage of Shazand, Khansar and Dalan faults has been established. The purpose of this study was to investigate the possibility of Neotectonic activities in that part of Murghab basin which is located in the path of Shazand fault.
Methodology: A digital height model with an accuracy of 30 meters was prepared for this area and geological layers were added to it. Then, this basin was divided into 18 sub-basins and the measurements of Hi, Bs, Af, SL, S, Facet%, V indices were performed in Arc Map, Arc View and Global Amper software environments and the relative index Active tectonics (IAT) was calculated. Field visits were also conducted for further studies. In the final analysis, all data were combined.
Findings: The relative tectonic index (IAT) has shown the general sub-basins to be active to semi-active. Along the path of Shazand fault, displacements were observed in the Slikenside of the fault. The network of waterways in the Murghab Basin shows evidence of 90-degree rotation and reorientation of waterways, Which is related to Neotectonic activities and the fall of the base level and the rupture of the lake in the area.
Conclusion: Following the studies conducted in neighboring areas, evidence of Shazand fault activity in this area was also presented and proven. Given that tectonic activities are likely to continue in the future and could be dangerous to humans and facilities in the area, policymakers need to consider this in their future planning.
Keywords: Neotectonic, Geomorphic indices, Shazand Fault, Morghab River
