| Abstract | ||
| The arrangement of fold types and thrust system within the study area was analyzed using satellite image, GIS and field work. Attitudes of the bedding planes were extracted through eleven QuickBird scenes using the Structural Contour Lines (SCL) method. These results have been compared with dip angles and dip directions, which measured in the field. Building of SCL based on high spatial resolution of QuickBird images, and Digital Elevation Models (DEMs) is a key role to understand the geometrical properties of the anticlines in this study. The aim of this paper is to determine the geometric and the structural deformation analysis by using geoinformatics techniques and to update the geological and structural map of the High Folded Zone of the Zagros-Taurus orogenic belt, northeast part of Iraq. We generate DEMs from stereo image of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) along-track sensors. We simulated the geometry of one anticline based on the 3D representation modeled. According to the structural contour map, the faults within this area formed sequentially as the deformation front migrated from the collision zone towards the NE. Movement up thrust ramps created fault-bend folds behind which serial detachment folding developed in the cover. | ||
