Abstract

Abstract. Formation, classification, morphological, physiochemical, and mineralogical characteristics of Bushehr-Borazjan soil was evaluated. The region soil was of calcic kind. Furthermore; the humidity regime and thermal regime were of Aridic and Hyperthermic respectively. The region is associated with average yearly rain of 234.85 mm. On the other hand, the average yearly temperature is 25.2. As mentioned earlier, the main purpose of this paper is to evaluate physical, chemical, morphological, and mineralogical characteristics of the region soils so that they could be classified; Hence, first , the physiography was determined .Then, several profiles were installed in different physiography units . Next, considering the chosen profiles, the samples are brought to the laboratory for further investigation. Considering the latter sentence, six samples, in hope of mineralogical analysis, were chosen. It is noteworthy that the soil formation, because of hot and dry climate, was weak. Furthermore; the sample pedons were of cambic, calcic, and salic diagnostic horizon. The main two soil order were: Entisol and Aridisol. The known minerals were as follow: Chlorite, Illite, Smectite, Kaolinite, and Polygorskite. Finally, there was a subtle difference between the pedons’ mineral kinds..
