Remote Sensing And Gis Analysis Of Spatial Distribution Of Fracture Patterns In The Makran Accretionary Prism, Southeast Iran, Shankar Babu Pokharel
Geosciences Theses
This study shows that remote sensing and GIS are powerful tools in identifying geologically induced lineaments from digitally enhanced ETM+ satellite imageries and the digital elevation model (DEM) in remote areas such as the Makran accretionary prism, southeast Iran. The presence of the conjugate shear fractures in the eastern part, along with the extensional, and the presence of reidal sets associated with the subsidiary fractures of the Minab-Zendal fault system in the western part, suggests that the structural pattern changes from pure shear to simple shear from east to the west across the prism. Moreover, the gradual increase in the …
Kinematic And Tectonic Significance Of The Fold- And Fault- Related Fracture Systems In The Zagros Mountains, Southern Iran, Katayoun Mobasher
Kinematic And Tectonic Significance Of The Fold- And Fault- Related Fracture Systems In The Zagros Mountains, Southern Iran, Katayoun Mobasher
Geosciences Dissertations
Enhancement methods applied on various satellite images (ASTER, ETM and RADAR SAT-1) facilitated the identification and mapping of tectonic fractures in the Zagros fold-and-thrust belt in southwest Iran. The results of the fracture analysis on these enhanced images reveal four principal fracture sets within each fold structure: (i) an axial set defined by normal faults oriented parallel to the fold axial trace, (ii) a cross-axial, extensional fracture set oriented perpendicular to the fold axial trace, (iii) and two sets of intersecting shear fractures, oriented at an acute angle to the cross-axial set. Study of the enhanced images also revealed five …
