Abstract :

Iran, because of its special geographical conditions of various geological and geomorphologic properties and also diversity of climate, is challenging with many different catastrophes including
mass movement which cause plenty of damages. Geological factor, especially type of geological formation is considered as an innate element to occur mass movements. To determine different
geological formation tendency on mass movement occurrence, it is necessary to consider mass movement density occurring on different geological formations. In this study, performed bar domain, with area of 5399 hectares, that is 33 km far from north of Neyshaboor, numerical layers of geological formation and mass movements have been provided in GIS in order to estimate the effect of each formation on mass movement occurrence. Then diagrams have been drawn by statistical software and finally area percentage of each type of mass movement on formations of the zone has been provided. The results showed that Delichay formation and Lar formation have the most effect on mass movement occurrence and 54.3% and 40.2% of area mass movements occur on them, respectively.
