Study on Gourband Fault Activity on the basis of Neotectonic Evidences (Northeast of Torbat-e-Jam)


Gourband is the largest fault in the Alluvial Sediments of Torbt-e-Jam Plain. This fault is extended from northwest to southeast. Regarding its adjacency to the town and various villages, it is important to study Geotectonic activity. It is found that there are various geomorphologic abnormities along Gourband Fault. In this research, the effect of current movements of this fault on the structural Geomorphology of this zone has been studied. Fault scarps redirecting rivers and channels, folds of quaternary deposits and discoloration of sediments in the fault fields are important geomorphologic indicators that found in the desert site and in association with movement on Gourband Fault. The dip of fault is 50-60 degrees. The reverse component causes uplifting that forms maintains and it controls the current topography of the areas. Also, direct of waterways indicates direct of moving strike- slip of fault. Regarding dextral displacement of these waterways, it is found dextral strike-slip movement in the fault. Elevation of Neogene’s Sediments of the fault surface indicates uplifting and reverse component in the fault.
