Abstract

Detailed geological field investigations in the SE Zagros Mountains reveal that this portion of the Zagros was formed by epeirogenic vertical uplift. This vertical movement probably started in the Early Paleozoic and continued through geologic time, as shown by disconformities and dominantly shallow-water sedimentary rocks. Movements of Infra-Cambrian salt may have contributed to this vertical uplift to produced box-type folds which are geometrically and genetically different from folds in the NW segment of the Zagros geosyncline. Three late stages of vertical uplift with different magnitudes were measured and studied. Terraces along the Mehran River, elevated alluvial cones, and elevated ancient shorelines are among the most spectacular features supporting the vertical uplift of this region.
