Dehaj-Sarduiyeh area is located in the central Iranian volcano-sedimentary complex, southwest of the Kerman province. The study area, in the southern part of this complex, is located with the copper mineralization which is mainly of porphyry type and is associated with extensive hydrothermal alteration. This area has a great potential as far as tertiary porphyry copper deposits are concerned. To provide guides for exploration of porphyry copper mineralization at a district scale, we examine the spatial association between known 16 copper deposits and fracture in the area. Analysis of the lineaments interpreted out of ETM+(band8) data is recognized as another method for locating porphyry type copper mineralization. There is a close correlation between photolineament factor values and the known copper mineralization in the area.Keywords

Asmari anticline (with 30 km length, 10 km width&1391 m height) is a NW-SE anticline in the North of Dezful Embayment sub-basin of Zagros. Anticlines of Zagros are signal for oil resources. Hence, Asmari anticline is analyzed, because it should be extended to trap. Items such as tectonic system after and before trap forming, detection of workable traps and finally resolving proper points for well drilling are investigated. We found that there is a relation between growth of Asmari anticline up Asmari fault, fracture spread and first oil migration in Asmari formation. As a result, with reference to Asmari thrust depth, Khami and Dehram groups could be suggested as a proper oil reservoir.Keywords

This study records evidence of neo-tectonic activities in Tehran area. The aim of the study is to investigate the seismic sources in Tehran area and Mosha fault has introduced as the most active fault. The high seismicity potentials have appeared by integration of structural geology and active tectonics studies. Movement potential evaluation of the main faults in the current tectonic regime show that the North Tehran fault have 90% potential to movement. Also, geomorphic indexes indicate the presence of differential uplifting in the geological past. Recent activity of Tehran area is investigated by a large number of geomorphic indexes such as: drainage basin asymmetry, stream gradient. The stream network asymmetry was studied using morphometric measures of transverse topographic symmetry, asymmetry factor and drainage basin shape.

Sabzevar ophiolite zone (SOZ) is in north of Central Iran that separated Kop-e-Dagh Sedimentary basin (in north) from the Central Iran plateau (in South). The evolution and replace time of this ophiolite complex has been respectively in upper Cretaceous and Middle Campanian to Upper Mastrishtian. This ophiolite belt contains a large amount of ultramafic rocks, small masses of Gabbro and thick sequence of submarine basaltic lavas. This study surveys the brittle structures that developed during the mountain building process to decipher the history of polyphase deformation. Analytic inversion techniques enabled us to determine and separate different brittle tectonic regimes in terms of stress tensors. Results indicate that oldest generation of stress on the area after the adoption of the ophiolite (Middle Campanian to Late Mastrishtian), is the tensile stress regime. Average direction of σ1 stress axis in this regime is 251/81. This tension is Because of subsidence of ophiolites after the adoption (located) on ground surface. Middle generation of stress has been strike slip regime and average direction of σ2 stress axis in this regime is 323/62. Finally, the newest generation of stress is compressional regime with an average direction of σ3 stress axis 308/81. In this regime σ1 direction is 183/05 that has caused re activity of main pre-existing structures with N121 direction. Our reconstruction of stress fields suggests an anticlockwise reorientation of the horizontal s1 axis since the located of ophiolites on the ground and a significant change in vertical stress from σ1 to σ3 since the late stage of thrusting. Transition from tension to compression has been strike slip movement. Ratio of elliptical stress in any of the regimes, respectively, from old to new is 0.63, 0.75 and 0.62 that due to overcome of shear regimes, average form of stress elliptical in area, is intermediate between the prolate and oblate forms.Keywords
