Abstract

In this study the effects of SERPENTINE rocks on some physico-chemical properties of SOIL and waters have been considered. The serpentinite is the products of pyroxinite and dunite alteration. The dominant mineral of serpentinite is SERPENTINE and a less amount of chlorite and magnentite. The mentioned rooks are very sensitive to weatheying and have considerable effects on SOIL and water quality. The main mineral of SOILs derived from SERPENTINE rooks is smectite (sapponite) and with less quantity of SERPENTINE.According to the chemical analysis conducted it was observed that there is no smectite mineral in source rocks, thus the source of smectite in SOIL is neoformation. SOIL reaction (pH) varies from 8.2-8.6 and therefore it is alkali. The reason of alkali pH is high concentration of Ni and Mg in SOIL solution. The amount of Cr in the bed rocks and SOIL consist of variable amount from 1362 to 2300 ppm in SERPENTINE and 700 to 1900 ppm for SOIL matrix. The amount of Co in parent rocks varies from 80-185 ppm and for SOIL matrix from 98-270 ppm respectively. The amount of Ni varies from 1600-2692 and 1800-2850 ppn for mentioned rocks and SOIL matrix respectively. The amount of Ni increase with depth but there is not significant correlation between of Cr and Co with SOIL depth. Addition-Reduction percentage of different elements during SOIL formation show that amount of SiO2, FeO and MgO are less in SOILs in contrast to the bed rocks and the amount of Al2O3, CaO have a increasing rate for formed SOIL. The ratio of Ca/Mg in SOIL solution varies from 0.2-0.89 and 0.18 to 0.67 for affected water. The low ratio of Ca:Mg are caused bittering of water. The amount of available K and calcite in SOILs is low, ECe is lees than 1 dsm-1, SOIL texture is sandyloam to loamysand with large amount of residual gravells. According to stability of SERPENTINE the most of SOIL samples are seems to be unstable.
