Abstract

Clearly, clay minerals with their particular characteristics are considered as soil active part. Without recognizing soil clay mineral, recommendation on plant nutrition, soil conservation. Soil mechanical properties would not be accurate. In addition to soil physical and chemical studies which lead to recognition of soils, soil micromorphology caused to better judge me soil condition. This study was conducted to investigate the type and origin of clay minerals via several profiles in LORDEGAN hilly lands. The profiles were located in two kinds of land uses including forest and dry farm at different SLOPE POSITIONs as sampling sites. The soil samples were collected from two depths of soil horizons to determine CEC, soil texture, OC%, calcium carbonate equivalent, X-ray diffraction and micro-morphological study via undistributed soil sampling. The results illustrated that the dominating clay minerals are illite, smectite, chlorite and chlorite-smectite as mixed minerals. According to the result, the origin of minerals in both land uses and different SLOPE POSITIONs is inheritance from parent material. These minerals are mostly apparent in lower positions of the slope. Thin sections investigation of some horizons in the both land use in different SLOPE POSITIONs showed that there was no difference regarding the kind of soil voids and C/F ratio between two sampling sites (including land use and SLOPE POSITIONs). Complex packing voids, vugh and planar voids were the most dominant voids of these profiles. The observed b-fabric in all horizons was crystallitic and soil structure in back slop was subangular blocky. In all horizons of rainfed land use except for shoulder and back slop, clay films and calcite coatings were observed.
