Abstract :
This study has been conducted in order to determine the pedo-genetical distribution of minerals of the great groups of Rhodoxeralf and Rendoll Soils showing distribution in Yatağan River basin, in the city of Muğla in Aegean Region. Soil samples were taken from different layer or horizons that were observed in pedons located in summits, ridges and back slopes physiographic units of the Yatağantepe and the Kayışalanı regions. Grain size distribution and types and amount determination of minerals of the soil samples from Rhodoxeralf and rendolls were examined by polarize microscope observations, x-ray and the other laboratory analyses. Since minerals in this group are quite resistant to physical weathering and chemical dissolving, it was observed that they decreased in amounts along the dept of pedon. It was observed that the amounts of the mineral hematite, calcite, illite, feldspar, mica and zircon increased through the deepness of pedons due to leaching process from upper horizons to the lower horizons. All horizons of Rendolls, classified in Mollisol ordo, contain great amounts of free CaCo3 since formed on main material which is highly calcerous. The amounts of opal, hematite, felspar, quarts, hypersthenes, hornblende, augite, tourmaline and opaque group minerals in Rendoll soils decrease in the pedon, while the amounts of the minerals of calcite, illite and mica increased in the pedon.
