Systan & Baluchestan Geotourism Atlas
Systan & Baluchestan is in southeastern Iran and shares borders with Pakistan and Afghanistan from east, Oman Sea from south, Khorasan from north and northwest, and Kerman and Hormozgan from west.
It is under the effect of different climatic currents: Indian currents & monsoons and middle latitudes with extreme heat.
Natural mud volcanoes, Dasht-e-Lut sand pyramids and movement of san dunes toward south and southeast are among the geological attractions of Systan & Baluchestan.
Usually east of Iran is considered as an independent unit in geological studies.
Southern part of Systan & Baluscestan (Makran) is subsiding gradually due to the thickness of sandy clay deposits with more than 1km depth (third era).
Therefore, steep subsidence gradient of Indian oceanic crust results in the creation of mud volcanoes and mineral springs.
Elevations of Systan & Baluchestan belong to the seconds and third eras and their rocks are mainly limestone and gypsum. Some geologists believe that some mountains (such as Taftan) belong to the late third and early fourth era.
Sistan is limited from north, east and south by low plains and sand dunes, and from west by mountains (Pliocene) and evaporative sediments.
There is a north-south fault between plains and elevations.
Also, Sistan is characterized by fine-grained sediments.
