Formation and Mineralogy of Soils Developed on Different Geological Parent Materials at Different Soil Temperature and Moisture Regimes

This study was conducted in six soil profiles to evaluate soil formation and to determine the dominant clay minerals of soils which are formed on different geological parent materials anddifferent soil moisture and temperature in aglasun (burdur), kepez (antalya), sandikli (afyonkarahisar), aksu (isparta) ve buldan (denizli) districts. it was determined that the profiles were in mesic and thermic temperature regimes, while they are in xeric and ustic moisture regimes in the study area. while the five of profiles consist of sedimentary rocks which were different geological age and composition, the last profiles was consisted of metamorphic rocks. it was found that the defined profiles belonged to inceptisols (4), mollisol and alfisol soil orders and in these profiles, ochric and mollic surface horizons and cambic, calcic and argillic subsurface distinctive horizons were defined. in the inceptisol order, calcification, decalcification, rubification and podzolization; in the mollisol soil order, calcification, melanization; in the alfisol order, rubification processes were found to be effective separately or in different combinations, depending on main material and deposition positions of profiles. smectite was found to be dominant in profiles where they were relatively low drainage base position. it was determined that illite-smectite intermediate layers minerals were dominant in other profiles which were sedimentary origin. it was also determined that the kaolinite mineral was accompanied weathering products of gneiss parent materials.
