Although Turkey has a large amount of volcanic material, it does not have a sufficient amount of work about Andosol identification. The objectives of this study were to investigate the physical and chemical properties, weathering processes, and pedogenetic products of soils developed from Andesite/Thracyandesite on hill Cunur in Isparta. The physical and chemical properties were determined for four profiles derived from these rocks in Cunur Hill (Isparta, Turkey). The four profiles showed a surface enrichment of organic matter (1.96-5.53%), a neutral pH (5.3-6.9), and a generally low base saturation (11.35-24.91%). The low concentrations of free iron oxides (0.034-0.153% Fe) and clay (14.02-35.29%) indicate a relatively low degree of weathering. The results revealed that the amount of sand and coarse silt fractions were higher than 30% in all profiles. The bulk density is higher than 0.90 g.cm-3 in all profiles. Meanwhile, Al +1/2 Fe percentages (by ammonium oxalate) are lower than 2% in all profiles. pH values in NaF are lower than 9.5 in the some profiles. Selective extraction of soil samples in all horizons yielded the following trends: Fe-d > Fe-o > Fe-p in profile Kl, K2 and G1 and Fe-d > Fe-p > Fe-o in profiles G2 in addition, according to selective extraction solution of aluminum, it was found in northward profiles Al-o > Al-d > Al-p, While in southern side profiles have Al-o > Al-p > Al-d order. According to selective dissolution analysis, non-crystalline minerals like allophane and imogolite were not found. The only non-crystalline minerals found in great quantities Al-humus complexes and in small quantities ferrihydrite were determine. The semiarid climate and long and dry summer season of volcanic areas, a low rate of weathering, inadequate Si leaching as a result of low precipitation and also very small amount volcanic glass content of parent materials in studied soils prevents andic soil properties. The major factors determining soil genesis on Cunur Hill would appear to be climate, by affected leaching regime. Classification of the studied profiles according to Soil Taxonomy indicates an Entisol (Lithic Xerorthent).
