SEDIMENTARY FILLS OF THE BOR BASIN (CENTRAL ANATOLIA): CLIMATE AND ENVIRONMENT DURING EARLY HOLOCENE AND THE MID-HOLOCENE
Holocene alluvial and lacustrine deposits characterize the so-called Quatrnary fills of the Bor Basin (central Turkey) and consist of conglomerate, sandstone, mudstone, limestone, and paleosol-calcrete units. To understand the any climate changes hidden in sedimentary rocks and paleosols and pedogenic processes mentioned above, it is planned to perform XRD (X ray diffraction), SEM (Scanning Electron Microscope), XRF (X-Ray Fluorescence) and stable isotope element analysis due to determine for the analysis of geochemical, mineralogical sedimentogical compositions. During the Late Glacial, a shallow freshwater lacustrine phases and paleosols are identified from 40 000 to 11 000 yr BP. The Holocene environmental evolution shows a period of paleosols, marsh or shallow lake sedimentation from 6 000 to 5 500 yr BP. This period is interrupted by second drought period and this corresponds to calcareous rich mudstones in the area. This is covered during the Late Holocene by the renewal of marshes, shallow lake sediments and paleosols. The temperature increase during the last period, uprising and closed basin structure, salinization started taking place and the process still continues due to palaeoclimatical changes.
