The quantitative assessment of geodiversity of Proposed Geopark of West Khorasan Razavi to protect its geoheritage.

Identifying various natural phenomena is essential for many scientific branches. geodiversity has provided the foundations for providing the living conditions of modern societies and puts it at the disposal of man natural resources, such as construction stones, aggregates, mines, natural gas, oil and groundwater; it forms the basis of agricultural land and fertile soils; Affects our place of residence; enhances the valuable and special landscape around us. In order to assess the perspectives used in geomorphology, in addition to the values of cultural, scientific and economic diversity, also from geodiversity, to provide more reliable data for the protection of the geological heritage. The proposed geopark of West Khorasan Razavi has unique forms and geological heritage dating to the Cretaceous. Therefore, it is essential that the geodiversity is evaluated to list priorities to protect heritage. To do this first, collected required documents and maps and field observations, processed map with GIS software, grided and calculated the diversity of geomorphology, hydrology and geology phenomena in each grid, then, the geodiversity map was prepared in four categories: low, medium, high and very high. The findings of this research show that 9.3% of the area is very high in geodiversity, which is observed in the north and southwest of the region. 11/5% of the area has a high geodiversity that is most seen in the north and west of the region. 37/2 % of the region has moderate geodesy, which can be seen in all areas except the southwest and center. 47.4% of the geodecimal area has a small amount, which are centralized in the central and southeast, where the wind process is dominant geomorphic formation of the region.
