Abstract

Sedimentologhy studies of Karaj alluvial fan caused the climate were surveyed in the time of sedimentation of alluvium of a,b,c in plio - plioctocen. Existence of PYROXENE and plagioclase with rounded quartz (with different properties and degradation level) in alluvium of a and c indicate ancient sedimentary cycles, fast transportation and sedimentation. Observation of unanalyzed PYROXENE and plagioclase indicate moisture conditions in source but fast transportation and sedimentation have prevented for continuing.The percentage of chlorite is more than the other clay minerals and also observation of PYROXENE in alluvium of a,b,c indicate the lack of wet conditions in Karaj sedimentary basin. Considering the lack of moisture in Karaj sedimentary basin, the source of MIXED - LAYERs of clay minerals can lit be neoformation and transformation .so they have inheritage origin.Considering the kind of minerals in alluvium of a,b,c and the color of sediments , the climate was cold and dry with short period of warm and dry in Karaj sedimentary basin in plio – plioctocen. Existence of debris flow in alluvium of a,b,c and inheritance sources of clay minerals indicate wet conditions so the climate of Karaj Water -shed was cold and wet in plioplioctocen.
