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.
