“…The SW-NE oriented contraction has led to the development of NW-SE trending, SW-verging folds, and NE-dipping thrusts in the Phanerozoic sedimentary strata covering the Afro-Arabian basement, above a detachment zone of the Infra Cambrian-Cambrian Hormuz evaporate (Kadinsky-Cade and Barzangi, 1982). Therefore, study area is an active region (Arian et al, 2002;Qorashi and Arian, 2011;Arian, 2011) same to Alborz at north Iran (Arian and Pourkermani, 2004;Khavari et al, 2009;Arian et al, 2011a;Arian and Bagha, 2012) and Central Iran (Pourkermani and Arian, 2001;Arian et al, 2011b;Nouri et al, 2013).…”

Quantitative analysis is a major factor controlling landform development in tectonically active regions, and it has significantly affected fluvial systems and mountain-front landscapes in the Jarahi-Hendijan basin area of the Zagros, southwest Iran. The area is located along the high Zagros, Zagros simple folded belt and coastal plain. It is an outcome of the SE-NW oriented tectonic conversion that initiated in the Late Cretaceous and strengthened during the Early Miocene due to the collision of the Arabian and Eurasian plates. To assess tectonic activities in the area, we have analyzed geomorphic indices: the stream-gradient index (SL), drainage basin asymmetry (Af), hypsometric integral (Hi), valley floor width-valley height ratio (Vf), drainage basin shape (Bs) and mountain-front sinuosity (Smf). These indices were combined to yield the relative active tectonics index (Iat) using geographic information systems (GIS). Based on Iat values, the study area was divided into four parts: Class 1 (very high relative tectonic activity, 11.5% in area); Class 2 (high, 27.7%); Class 3 (moderate, 23.4%), and Class 4 (low, 37.4%). The results are consistent with field observations on landforms and the regions with high relative tectonic activity mostly correspond with the active mountain front faults at the northern part of study area. The coastal plain in the west and southwest of the area show the lowest relative tectonic activity (class 4).

“…The folding and regional uplifting of Zagros proforeland basin occurred at the end of Early Miocene. Therefore, Zagros is an active fold and thrust belt [34] same to Central Iran [35]- [38] and Alborz [39]- [43].…”

Based on geographic distribution and geological setting of salt plugs in southern Iran, three salt diapiric provinces have been distinguished. These provinces include the Hormuz, Shiraz-Kazerun and Nyriz-Jahrum sub-basins. There are more than hundred salt plugs which they have been formed and developed in the southern margin of Iran. The salt structures that originated from Hormuz formation in these areas have been restricted and separated from each other for the first time in this paper. Salt diapirism of these provinces has been triggered earlier by Halokinesis in the Zagros and Persian Gulf basins, but it has affected later by tectonic forces, because orientation, shape and position of salt plugs have been followed from convergence regime (especially in the Zagros hinterland). In the other hand, based on our results from salt plugs in Persian Gulf foreland basin and the Zagros hinterland, Halokinesis triggers has been affected more than Halotectonic forces.

“…This area has an active regime in compared to the north Iran [4]- [19], the central Iran [20]- [28], the south Iran [29]- [35] and salt diapiric areas in Iran [36] [37]. Also, some concepts of copper mineralization in Iran have investigated by [38]- [42]. In this area, volcanic rocks are commonly Eocene andesite, Oligocene-Miocene diorite to granodiorite (as stocks) and late Miocene quartz diorite dykes.…”

The Ardestan-Kahang area is located in Urmieh-Dokhtar Magmatic Arc. This area is situated in Ardestan, Kouhpayeh, Kajan and Zefreh in 1:100,000 geological maps. In order to extract mineralization zones related to copper mineralization and accessories elements, and also identify Argillic, Prophylitic, Sericitic and Siliceous alteration with major and minor lineaments, various kinds of algorithms, band ratio and personal interpolation have been utilized. The applied methods for extracting alteration consist of LS-Fit (Least Square Fit), Matched Filtering (MF), Spectral Angle Mapper (SAM) and Spectral Feature Fitting (SFF), band ratio and visual interpretation. Comparing different outputs of utilized algorithms illustrates that the best algorithm for argillc alteration extraction are Matched Filtering (MF) and Spectral Feature Fitting (SFF), with visual interpretation, and for argillic alterations the visual interpretation with RGB: 468 that has seen pink-red color. For prophylitic alterations the utilized algorithms are Matched Filtering (MF). Lineaments have extracted with visual interpretation on satellite images and it is revealed that in areas where the fracture density is greater, conditions are more suitable for copper mineralization.
