Research on the evolution of landforms in different sectors shows that the features of the region have come to their current form by orogenic and epeirogenic processes as well as external processes. However, these processes exhibit dry characteristics of Dashtiar. The oldest rocks in the north are related to the late Cretaceous and the north of colored mélange, and the oldest deposits are in Dashtiari, belonging to late Miocene, and consisting of a set of rocks and fine-grained marl-conglomerate. The coastal landscapes of the Omani coast include Hezar-Darreh (a thousand valleys), muddy flows of the marl, hills of the tafoni caverns, deep watercourses of coastal plains, two sandy beach lanes, sandy hills, desert zones of clay marl. The geomorphologic phenomena of the Omani coast include mud volcanos, sea terraces, coastal, foothill and alluvial plains, alluvial cones and hills. In the glacial period and the period between glacial periods, water and wind are the dominant factor of erosion respectively, and the laminated terraces and exploratory and mechanical erosion are evidences of rainy periods in this region.
