“…They are related to lower member (M 1 ) of Upper Red formation that has been under weathering now. Thus, they are different from other salt domes and diapirism in Iran that investigated by many researchers [9]- [20]. Based on previous work on the mud diapirism [21] [22] and neotectonic regime in Iran [23]- [28], Zagros in south Iran is the most active zone [29]- [69].…”

The salt domes of the west Zanjan (Central Iran) are the most important structures in the study area. They have been formed by the uplifting and erosion together under low humidity and dry and warm climate condition. The salt rocks with near to 200 meters thickness are related to lower member of the Upper Red Formation (Early Miocene) that deposited in the inverted back arc basin. They have been formed in the Central Iran basin after the ArabianEurasian convergence. Based on filed works and preparation of geologic map, salt domes have been cropped out during regional uplifting and erosion along hinge zone of a longitudinal anticline. Also, there is no evidence for salt diapirism and so, they are different from some salt diapirs in the southwestern margin of Zanjan that is investigated by other researchers.

“…The most common deposits of storms in the rock record are sandstone beds deposited under powerful near-bottom water motions produced by waves and currents ( Figure 15). Both tsunamis and large storms cause death and damage along low-lying coastal areas, and both occur with regularity, although tsunamis are much less frequent than coastal storms [27] [28] [29]. Because of their infrequency, tsunamis are poorly documented in historical records for many of the areas where they pose a threat.…”

Makran zone is one of the largest accretionary wedges in the world. This research had used methods such as studies of Office and library, field observation and surveying that several field visits, sampling, registered structural evidence, Laboratory studies, Data analysis, interpretation and conclusions. The most important objective of this study is assessment of Tectonics and hazard Potential in Coasts the Oman Sea based on tectonics and sedimentology. The northward movement and subduction of Oman oceanic lithosphere beneath Iranian micro-plate at a very shallow angle and at high rate is responsible for active orogenesis and uplift. Detailed seismological and geological information in planning is extremely essential to avoid any disaster. It is to be remembered that seismicity does not remain fixed in an area but migrates slowly with time. Thus, the planners are expected to be more concerned with the building code and prevention strategies. It is also important to mention that the Coastal zones are always vulnerable to natural hazards and liquefaction. The geomorphology of an area is the first indicator of on-going tectonic activity. In order to measure the amount of deformation due to tectonic processes, the initial geometry of the geomorphic markers is reconstructed accurately. Study of sediments shows that abundant shell fragments organized in laminae also favor a storm origin. Storm deposits contain no internal mud layers and rarely contain pieces of mud. Maximum deposit thickness is near the shore, and landward thinning of the deposit is commonly abrupt. Storm deposits fill in topographic lows, and the upper surface is relatively uniform in elevation alongshore. Finally, landforms of tectonically active regions and sediments are controlling factors interactions between tectonic, sedimentary, climatic, and surficial processes.

“…SE part of magmatic arc has formed on southwest margin of east-central Iran microcontinent [3]. 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].…”

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.
