Abstract
Since geological formation is very important in the process of desert and desertification, in this article lithology, stratigraphy of the Boushehr province was studied with the help of 1:100000, 1:250000 scale maps of G.S.I and N.I.O.C using GIS methodology. Quaternary formations and most of the evaporatic formations in the province were recognized. Saline and evaporatic formations were introduce as “Primary deserts”. Then with the help through overlaying the drainage network on the basic map of Quaternary formations, the secondary deserts was then recognized this kind of desert possess the evaporative material such as gypsum and salt. Both of these processes (The primary and secondary deserts) have formed Boushehr province deserts. final Results showed that 47% of Boushehr province area is classified as desert including 592041 ha “Primary deserts” and 574579 ha as ‘secondary deserts”. It was concluded that most important geological formation effective in deserts formation in Boushehr province comes from Hormoz series, Gachsaran, Mishan and Aghajari formations.
