Title

CLAY MINERALOGY OF GYPSIFEROUS SOILS DEVELOPED ON DIFFERENT LANDFORMS IN THE EASTERN PART OF ISFAHAN

Pages

  93-93

Abstract

 CLAY MINERALS deserve special attention as they play a crucial role in many soils. The clay mineralogy of five Gypsiferous soils from different LANDFORMS in eastern Isfahan was investigated using X-ray diffraction (XRD). In addition, soil aggregates and wind-deposited sediments were examined by scanning electron microscope (SEM) and analyzed by energy dispersive X-ray analyzer (EDX(. The results indicate the presence of PALYGORSKITE, mica, kaolinite, chlorite, and quartz with a trace amount of vermiculite and randomly interstratified layers in all soils. SMECTITE occurs in soils of both the piedmont plain and old river terrace, but not in the alluvial fan soils. Mica, chlorite, quartz, and kaolinite were probably inherited from the parent material. PALYGORSKITE seems to increase with depth in the alluvial fan, whereas, in the old terrace soils, this clay mineral decreases with depth. PALYGORSKITE present in alluvial fan soil appears to have been formed authigenically when the basin was covered with shallow hyper-salute lagoons toward the end of the Tertiary. PALYGORSKITE in the old terrace seems to be mostly detrital and an eolian origin of PALYGORSKITE is likely because a large amount of PALYGORSKITE is present in upper soil horizons. A higher proportion of SMECTITE in deep soils of the old terrace, as compared with PALYGORSKITE, suggests the possibility of authigenic formation of SMECTITE from PALYGORSKITE.
