The aims of this study are i-) to determine morphology, mineralogy, chemical and physical properties of four different soil profiles formed on two different parent materials and order, ii-) to classified according to soil taxonomy, and iii-) to investigate between physical characteristic and mineralogical properties. According to this study’s results, four soil profiles were classified as Calci Haplustert, Entic Haplustert, Chromic Haplustert, Typic Calciustert and it was determined that montmonilinite which is one of the swellable 2:1 smectite groups was found as dominate clay mineral followed by nontronite and kaolinite. Liquid limit and plastic limit of soils were determined between 53-70% and 27-40%, respectively. In surface horizon, liquid limit was found the highest value in Calci Haplustert while, Entic Haplustert has the highest plastic limit value. According to USCS classification, all soils were classified as high plasticity, inorganic clay (CH). In addition as classified according to their activity values, they were classified as no active clay. According to index properties and clay mineral all profiles can be said as swellable soils. According to analysis results, it can be said that studied soils including high amount of swellable smectite clay minerals have problem by taking into consideration of physical ground and soil engineering.
