Öğe Mineralogical and chemical changes in parent rocks and in soil ecosystems (Mazmili Da?I, Adana, Turkey)(2007) Gurel A.; Kerey E.; Lermi A.In this study, the region of Alada?lar-Mazmi{dotless}li{dotless} (Adana) has been selected as research area and covering on area of 95 square kilometers. A number of anatical methods including Attarberg, XRD, XRF and ICP have been employed to characterize representative samples collected from the soils developed partially weathered country rocks with respect to their chemical and mineralogical contents. Soil horizons did not well developed on the limesstone and ultramafic parent roks that include mainly harzburgite-dunite, ophyolite melange due to rapid weatering and steep topography. However, soil zones well-developed, forming terra-rosa over ohiolite melange and its debris. Clay species belonging to smectite, kaolinite, and mixed-layer groupes have been formed during pedogenesis. Clay contents and abundances vary depending on the morphology. Although the limestone and harzburgite - dunite dont contain quartz, the soils developed on them comprised significant amounts of quartz. Mazmi{dotless}li{dotless} area soils did not develop homogeneausly, they are rather inhomogeneous. MgO and CaO contents show depletion upward, whereas, the other major element oxides including, as Al2O3, Fe2O3, SiO2 and MnO increase. These soils are slightly basic and enriched in K2O, and Na2O. Heavy immobile elements such as Zr and Ti show strongly parent rock-controled distributions. A total of three soil profile has been investigated in this research. Chemical analysis indicated that the major and trace element chemistry of all three show good agreement with the world soil standards. Only difference noticed was anomalous chromium and nickel values due to the host rock chemistry.
