This study examines the evidence and effects of young tectonic activities based on the calculation of vertical changes in folds and thrusts in the western part of the Horst Shotori. Quantitative analyses of vertical changes in the western part of the Shotori and the study of factors affecting the extent of these changes have been the objectives of...

This research assessed stress regimes and fields in eastern Iran using fault-slip data and the tectonic events associated with these changes. Our stress analysis of the brittle structures in the Shekarab Mountains revealed significant changes in stress regimes from the late Cretaceous to the Quaternary. Reconstructing stress fields using the age an...

Abstract In the South Dezful Embayment, due to the sequence of the Zagros deformation phases and the Tectonic inversion occurrence in the Rag Sefid thrust fault, as well as the reactivation of the Hendijan fault, has been occurred a perpendicular interaction in the Zagros foreland faults that caused an important effect on the structural pattern of...

In order to evaluate the level of tectonic activities in the Shekarab Mountains, several geomorphic indices such as stream length gradient index (SL), valley floor width to valley height ratio (Vf), hypsometric curve (Hc), hypsometric integral (Hi), drainage basin shape (Bs), and relative tectonic activity (Iat) were calculated. Vf values show fast...

The calculation of the geometric values of the Tango anticline, including the L-parameter, the ratio of the size (R), the bluntness of fold (b(,the Fourier coefficients, and their position in the corresponding diagram, indicates that the tangu anticline is asymmetrical, and has a sinewave to chevron form. Due to the Aspect ratio of the Tangu anticl...

Eastern Iran, including the Sistan suture zone, comprises the boundary between Lut block and Afghan block. This research aims to reconstruct the stress regime evolution from the upper Cretaceous to Quaternary based on the brittle tectonic analysis. In this study, three episodic changes in stress regimes were recognized in the Shekarab Mountain usin...

In this research the Coulomb stress changes due to earthquake sequence that began in the 1936 to 1997 earthquakes in Eastern Iran and their triggering effect on the rupturing of adjacent faults were investigated. Obtained results revealed a well triggering relation between main shocks and later events on the Dasht-e-Bayaz and Abiz faults, respectiv...

Image logs of 13 wells in the Rag Sefid Anticline show two systems of fractures developed under two deformation phase in the Dezful Embayment. This deformation phases are folding resulted from Zagros NE contraction and reactivation of the basement fault rotated the fold axial trace within the Hendijan-Izeh fault zone. Folding phase comprises four s...

Image logs of the the Rag Sefid anticline show two present-day maximum horizontal stress orientations developed under two tectonic phases in the south Dezful embayment include folding resulted in Zagros contraction and reactivation of basement fault. In the eastern part of the anticline induced tensile fractures and borehole breakout orientations a...

Plastic behavior and significant thickness of the Gachsaran incompetence formation on top of middle carbonate units in the sedimentary sequence of the southern Dezful Embayment has led to the emergence of different styles of folding up and down of this formation and also the evolution of developed structures in the rocky units of this region. So th...

Analysis of seismic sections perpendicular to the fold axis and draw the circles surrounding on this profiles indicate the more bending in forelimb due to the more uplift in sedimentary units in effect the compression performance and thrust faults that caused fractures development and density in the southwest limb. Increasing loss of drilling mud i...

The alluvial fans are the condensed forms of the Quaternary and the covenant period, and their examination can provide researchers with useful information about the neotectonic regional activities in which they were formed. Geomorphic indexs are useful and reliable tools for the evaluation of tectonic activities because they can easily be identifie...

Image logs of 14 wells in Rag sefid anticline are showing 6 main fracture sets treanding N45, EW, N35, N100, N150 and N162 respectively. Development of fractures in the eastern part of the Rag sefid anticline, especially in the frontal edge, are in effect of the propagation fault related folding so that the most open longitudinal and cross axial fr...

Study area is located in the north east Iran, north shirvan fault zone. In the study area there is fault related folds that are displaced by right lateral strike slip faults. In this research, active tectonic of north shirvan fault zone were investigated by using geological maps, seismic data and analog model. Active tectonic investigations of stud...

The area to the W-SW of the Lut Block in Iran has experienced numerous historical and recent destructive earthquakes. We examined a number of faults in this area that have high potential for generating destructive earthquakes. In this study a number of faults are introduced and named for the first time. These new faults are Takdar, Dehno, Suru, Hoj...

The Shekarab Fault system is located at north of Birjand city has fault scarps parallel to main fault. For investigate the direction of migration, four cross-sections perpendicular to the fault has done. In all these sections, by moving from north to south, the older lithological units are trusted over younger ones. Units with low resistance includ...
