Deposits of terraces and alluvial fans are an important part of the sedimentary series of the Quaternary period that represents the characteristics of their upstream basins. In this study were determined 14 samples of these deposits were collected from the catchment of Kalshoor River in northeastern Iran. In each sample, geochemical and sedimentary characteristics, texture and particle size, element oxides of each of them were investigated. The particle size distribution of the sediments indicates average roundness, poor soreness and normal graining with sand, gravel and sandy gravel. The tectonic setting of these sediments on basing geochemical diagrams placed in the oceanic arc and continental arc setting. Also, determining the effect of weathering in the source area of these deposits using the chemical index of alteration (CIA) suggested the low degree of weathering and dry weather conditions in the source area.
