That in addition to playing an educational-scientific role, it causes to touristic development. In order to introduce and evaluate geotourism potential of Quaternary phenomena in Sedimentary basin of Gorgan Plain, this study is based upon library review, consideration of previous records in regional, zonal and national scales, field operations and photographic documentation. The results show that 75% of geotourism phenomena are in pattern and indicator level and 40% are placed in zonal site from the value and importance of each geotourism phenomenon points of view, respectively. Due to climatic changes, variety of weathering processes, zonal erosion system (Caspian-Alborz) and sea level fluctuations during Quaternary and ancient eras, Gorgan Plain has unique geomorphic evidences and landforms and natural structures such as continental, and coasteal sand dune with various forms and compositions, loess materials and ancient hills, tectonic-erosion origin lakes, mud volcanoes, meanders, and Gorgan-Rud and Ghara-Su deltas. Diversity of geotouristic phenomena of Quaternary in Gorgan Plain is absolutely prominent on national and the whole Caspian Sea basin scales and it is convertible to a zonal scale geopark.
