  Kinematic evidence of shear deformation in strain fringes of sphalerite mineral in an overturned limb of a fold structure are studied. Structural observation in Cretaceous rocks of Tiran Mine Area in west Esfahan, reveals a shear deformation in overturned limb of a hanging-wall anticline that has generated with reverse fault in the area. Orientation of strain fibers and their rotations in strain fringes of sphalerite minerals are used for determination of stress orientations and its changes during shear deformation process. This fabric indicates kinematic evolution of the overturned limb of a hanging-wall anticline and related reverse fault during folding. In this study, amount of stretching in strain fringes and their rotation are measured by object-centre path model. Manuscript profile

  Deformed rocks of the Ghasem Abad area are situated in the north-eastern part of the Kashmar-Kerman structural zone in the north-western part of the Lut block. In this study, the finite strain analysis was considered based on microstructural analysis of the different types of deformed rocks. The Fry method was used to determine 2D analysis of strain ellipsoid and the results were subjected to 3D strain analysis using Flinn diagram. The mean value of ellipticity (K) is about 1.91 located in the constriction field of the Flinn diagram showing strain intensity (D) of about 0.54. The intensity of the strain is increased so that the maximum intensities are distributed along strike slip faults of the area. The constriction and flattening ellipticity of the strain are remarked respectively from the northeast-southwest parts and middle part of the study area. The major axis of the strain ellipsoids in xy plane are sub-parallel to the NE-SW strike slip faults and were stretched by approaching to the main faults. Manuscript profile

  The marbles of the Khalaj area constitute a part of the Mashhad metamorphic complex which was affected by three stages of deformation. Stretches of the boudins, which occurred during the first stage of the regional deformation, are measured in seven stations. The data are used for two dimensional finite strain analyses by Mohr circle. The results indicate the ellipticity of the strain ellipsoids vary between 1.05 to 1.36, and the maximum shear angle is between 4 to 20 degrees. These results are in agreement with field observations indicating dominant pure shear deformation during the first stage. This deformation is marked by generation of continuous folds and chocolate box boudins. These types of boudins were formed due to the stretching in two directions. Results of two dimensional strain analyses also show half to one time positive volume change during first stage of deformation. Manuscript profile

  The aim of this study was to investigate the relationship between work-family conflict with psychological strain and life satisfaction, considering the moderating role of recovery of work. Parties pants are employees of Aghajari Oil and Gas Production Company that one hundred forty three individuals were selected by stratified random sampling method. Data were gathered by Work-Family Conflict Scale (Carlson, Kacmar& Williams, 2000), Recovery of Work Questionnaire (Sonnentag, & Fritz, 2007), General Health Questionnaire (Goldberg, 1972) and Life Satisfaction Scale (Diener, Emmons, Larsen & Griffin). Results indicated that work-family conflict had positively correlation with psychological strain and had negatively correlation with life satisfaction. Results also revealed that recovery of work moderated the relationship of work-family conflict with psychological strain and life satisfaction and positive correlation between work-family conflict and psychological strain and negative correlation work-family conflict and life satisfaction at individual with great recovery of work is weaker.

  The only outcrop of Asmari formation in the Dezful embayment is visible in the Asmari anticline. In order to estimate the strain parameters and shortening values, 26 geological cross sections were prepared perpendicular to the anticline axis. Based on the, interlimb angle measurements, the interlimb angles of the northern and central parts of the anticline show smaller angles than the southern parts. Determination of strain ratio (R) values indicates the strain values between 1.12 - 1.52. The zoning map of strain ratio values shows higher strain values in the northern and central parts of the anticline. Using geological cross sections and measuring the base length of the folded layer of Asmari formation (L0) and the straight length of the layer (L1), the percentage of shortening values were calculated in each section. The results show the occurrence of 1.8% to 12% shortening in different parts of the anticline. Shortening map of the Asmari anticline shows more shortening amounts in the northern and central parts of the anticline than the southern parts. Manuscript profile

  Kupal Oil Field is one of the important oil fields in the Zagros Basin, located in the eastern part of the Dezful embayment, adjacent to Aghajari Oil Field and Marun Oil Field. Some characteristics of the fold elements, such as the fold interval angle and axial surface, were determined in the Asmari folded horizon using the interpreted seismic profiles. Based on the deviation of the axial surface from the vertical surface and determination of shear angle and shear strain, minimum and maximum quadratic stretch and strain ratio (R) values were calculated in different parts of the anticline. With application of graphical functions the amounts of fold aspect ratio were determined along the anticline. Base on the results, the amounts of shear strain varies from 0.01 to 0.09 in deferent parts of anticline. Also results show the amounts of strain ratio in range of 1.25 to 1.38 and shortening about 5% to 17% in different parts of the kupal anticline oil field. Manuscript profile
