Abstract

The folded Zagros is a part of the active Zagros belt in the southwest of Iran. This area has main faults and active rock formations, the activity of these faults has somehow affected the strata and sediments of different geological periods. In this study First, by studying satellite images and aerial photographs, five locations were selected in different parts of Fars and the hinterland of Bandar Abbas, and finally, the tectonostratigraphy of these locations was compared with each other. The sinology column and the paleogeographical map of these regions in the Miocene period were reconstructed Using the data obtained from five places of folded Zagros (Bastak, Bahar anticline, Arjan plain, Saadi mountain and Yasouj). The obtained results and the resulting diagrams were obtained using the RockWorks geological program. the minimum and maximum stratified thicknesses of the Miocene period formation in these five studied points are related to Arjan Plain and Saadi mountain sections By comparing the obtained results and the Hesar diagrams and the isopach map. It was done between the studied locations, which shows the highest thickness of this formation in the Arjan plain section and the lowest thickness is in Saadi Mountain. The facies changes of sedimentary rocks of the Miocene period seem to be due to the operation and activity of bedrock faults such as Kare Bes, Sabzpushan, Sarvestan and Kazeron faults in this region.
