Central Iran and Necessity of Attention to Geological Phenomena in Development of the Old Cities and Villages.and Establishing the New Cities

Considerable part of the Central Iran is made by deserts and arid regions; therefore the Central Iran contains the lowest water content in the land of Iran. Because of the water deficiency and hard weather conditions, the indigenous people of arid regions have selected the springs and water found areas for living. But most of these areas are locations of deep strike sleep faults, shear zones, and thrusts, because these structures are able in lead and chanellizing the groundwaters. Living of the people in faulted areas presents many hazards that are earthquake, asbestos minerals in ophiolite melanges, radioactive-toxic and heavy metal elements mineralization, and Radon and C02 releasing. These hazards are obvious in Central Iran and attention to them is highly necessary in development of the old cities and villages and establishing the new cities.
