Özet

In this study, it was aimed to determine mineralogical and geochemical properties and differences in sources of the deltaic sediments from the area between Delicay and Tarsus rivers (Mersin). A total of 120 samples were taken from 40 different locations and from three different depth intervals to determine mineralogical characteristics of the soils from the study area. Furthermore, a total of 208 samples were taken for determination of textural and geochemical properties of the topsoils (0-15 cm). Mineralogical composition of soil samples were determined with XRD method, followed by determination of textural and geochemical properties with Bouyoucos hydrometer and ICP-MS methods, respectively. All the data obtained in this study were compiled into a Geographic Information System (GIS) database for preparation of various thematic map layers. Furthermore, scatter plots were also used to explore the relationship between the elements such as Ni, Cr, Co, and Fe. The results obtained from thematic map layers and scatter plots suggest that deltaic sediments in the study area originated from two different sources that differ in mineralogical and geochemical characters. According to mineralogical and geochemical differences in these sources, Quaternary sediments in the study area can be divided into two separate parts, such as western and eastern soils. This differentiation is caused by the geological materials brought from different sources by the Delicay and Tarsus rivers, which also played important roles in the formation of Quaternary sediments. Quaternary sediments in the study area display differences in textural properties in the north-south direction, whereas showing differences only in geochemical and mineralogical properties in the west-east direction.
