In this study,
it is aimed to reveal geochronological applications by coinciding the 87Sr/86Sr
analyzes carried out on carbonate units in Mersin, Karaman, Adıyaman and
Malatya regions with the accepted global seawater 87Sr/86Sr values and
supported by paleontological data. Three strontium analyzes performed on reefal
limestones observed in Mersin region yielded values of 0.708849-0.708902 and
0.708868-0.708902, and these values were supported by ostracod data and gave
ages between 9.7 and 11.4 Ma. In the Karaman region (Ayrancı basin), the data
of 0.708399-0.708951 were obtained from the analyzes made on 3 samples of
limestones-clay limestones. These data were confirmed by the planktonic
foraminiferal and ostracod ages from the studied carbonate units (Divlek-Mazı
Form.), giving ages of 7.1-20.9 Ma. Strontium analyzes were made from 4 samples
on Nummulitic limestones observed on ophiolitic units in Malatya-Adıyaman
regions. These analyzes were supported by planktonic foraminifer data and based
on the analysis results obtained (0.707663- 0.707784), the ages of 45.1-51.9 Ma
were given to the units examined.
