Vegetation cover establishment in mountains is the large part of arid lands vegetation. Rock slope and outcrops mostly landscapes there are in these areas. In this study on granitic and andesitic lithologies we surveyed relationship between vegetation cover and lithology. We measured weathering degree, number of crevice in regard to different dimensions in different scales and amount of vegetation in different slope degrees and aspects, also measured amount of EC, pH, organic materials, CaSo4 , CaCo3 , soil texture, N, P, K, Ca, Mg in soil . the results shows no significant different between vegetation of granitic and andesitic lithology, but there are significant relationship in 1 level percent between vegetation on different lithology and number of large crevice wide, medium crevice wide, large crevice depth and large crevice length. It was concluded that the crevice dimensions could be role in vegetation cover establishment on outcrops in arid lands.
