چکیده
Identification of different structural and geological events (Faults, Salt Domes) in seismic reflection data has always been one of the great challenges for seismologists. Seismic attributes are quantitative measurement interest of seismic characteristic. Around the world, a lot of oil discoveries and new oilfield development programs are occurring around or near these oil masses, and our country also has parts of the Zagros Basin, due to the existence of numerous salt structures that are massive and also There is an interlayer and layer that has an important role to resource trapping. In the central part of the Zagros fold-and-thrust belt of Iran, several diapirs of the Latest Precambrian–Early Cambrian Hormuz Salt locally decorate the surface exposures of a series of trending right lateral structure systems. In this study, we attempt to investigate the structural effects of structural deformation of salt in structural basins by collecting scientific achievements in the field of salt dome structures and finding the range of salt domes by using seismological methods. The high velocity of wave propagation in salt domes of the seismic sections in the pattern and texture of this structure, is different from that of other regions. An important category of seismic attributes that are used to identify salt domes are also textural and seismic attribute based on the grey level co-occurrence matrix (GLCM). The results show that the salt dome can be determined with high precision from its surroundings and from the salt dome.

Abstract
Identification of different structural and geological events (Faults, Salt Domes) in seismic reflection data has always been one of the great challenges for seismologists. Seismic attributes are quantitative measurement interest of seismic characteristic. Around the world, a lot of oil discoveries and new oilfield development programs are occurring around or near these oil masses, and our country also has parts of the Zagros Basin, due to the existence of numerous salt structures that are massive and also There is an interlayer and layer that has an important role to resource trapping. In the central part of the Zagros fold-and-thrust belt of Iran, several diapirs of the Latest Precambrian–Early Cambrian Hormuz Salt locally decorate the surface exposures of a series of trending right lateral structure systems. In this study, we attempt to investigate the structural effects of structural deformation of salt in structural basins by collecting scientific achievements in the field of salt dome structures and finding the range of salt domes by using seismological methods. The high velocity of wave propagation in salt domes of the seismic sections in the pattern and texture of this structure, is different from that of other regions. An important category of seismic attributes that are used to identify salt domes are also textural and seismic attribute based on the grey level co-occurrence matrix (GLCM). The results show that the salt dome can be determined with high precision from its surroundings and from the salt dome.
