Active Tectonics of Kangavar Area, West Iran

Abstract

Kangavar area is located in the Sanandaj-Sirjan belt in the west Iran. Geomorphic indices of active tectonics are useful tools to analyze the influence of active tectonics. These indices have the advantage of being calculated from Arc GIS and remote sensing packages over large area as a reconnaissance tool to identify geomorphic anomalies possibly related to active tectonics. This is particularly valuable that relatively little work on active tectonics based on this method is done, so this method is new and useful. Six geomorphic indices are calculated in the study area. Then, based on index of active tectonics values that calculated by average of six geomorphic indices, two relative tectonic activities levels are revealed. The low class of Iat is mainly in the sub-basins of 3, 4, 15, 16, 17, 19 & 22 while the rest of the study area has moderate active tectonics in the other sub-basins. Our results show that the moderate value is located on faulted area, which shows 3 class of relative tectonic activity.

Assessment of Relative Active Tectonics in Parts of Aravalli Mountain Range, India: Implication of Geomorphic Indices, Remote Sensing and GIS

“…We use geomorphic indices of active tectonics, known to be useful in active tectonic studies (Bull and McFadden, 1977;Azor et al, 2002;Silva et al, 2003;Molin et al, 2004;El Hamdouni et al, 2008;Mahmood and Gloaguen, 2012;Elias, 2015;Fard et al, 2015;). But this method was not applied before in the study area.…”

“…Master stream of sub-watersheds were used to calculate the Vf values of the study area ( fig.). Different researcher classified Vf index with different values (El Hamdouni et al, 2008;Fard et al 2015;Mahmood and Gloagaun, 2012). In this study area Vf index is classified as Class 1: (Vf<0.5), Class 2: (0.5≤Vf<1) and Class 3: (Vf≥1).…”

“…Hypsometric curve is the area-altitude relation can be described as a proportion of area above each proportion in elevation. The hypsometric integral (Hi) describes the relative distribution of elevation in a given area of a landscape particularly a drainage basin (Fard et al, 2015). The study of hypsometric curves as well as HI values provides important information about tectonic behaviour of the watershed along with erosional stage of the watershed (Moglen and Bras, 1995;Willgoose and Hancock, 1998;Huang and Niemann, 2006).…”

“…After that, West-Central Alborz and Lesser Caucasus hinterland has formed by deformation and regional uplift from SW part of Caspian Sea to Black Sea [1]- [3]. Based on previous works on the salt and mud diapirism [4]- [15] and neotectonic regime in Iran [16]- [21], Zagros in south Iran is the most active zone [22]- [42]. Then, Alborz [43]- [82] and Central Iran [83]- [98] have been situated in the next orders.…”

“…From tectonics point of view, it contains orogenic belt of Arabian plate. Based on previous work on the salt and mud diapirism [60]- [74] and neotectonic regime in Iran [75]- [80], Zagros is the most active zone [81]- [101]. Then, Alborz [102]- [150] and Central Iran [151]- [168] have been situated in the next orders.…”
