Abstract :
The studied area is about 360 Km2. To study the clay minerals of Kordan's area the researcherchose samples from the surface of alluvial fan and the interpretation of XRD indicates thefollowing results : 1-The clay minerals of area are mostly Cholorite and Illite . 2-The kind of area'sCholorite is sedimentary.Which is the result of erosion pyroclastics (TUFF). The origin of thementioned cholorite is heredity. 3-In the downstream of Kordan basin due to the analysis ofCholorite, The amount of the Cholorite has been reduced and the amount of Illite has beenincreased. In such a way that in sample (B1) the amount of the cholorite was 60% and it reduced insample (SM2) to 41/4% and the amount of Illite increased from 35% to 58/6%. 4- The amount ofMontmorionite is little in Kordan .5- In this basin the amount of Fe +2 and Mg +2 is most abundantand the amount of K+ ions is a little. And the climate is dry and semi-dry.
