The study was carried out on the Dağpazarı-Karaman route in the Mut/Mersin region. For this purpose, 2 measured stratigraphic sections were taken from the study area, and the Middle-Late Miocene series in the region was studied in detail by examining the ostracod fauna of the Mut, Dağpazarı and Ballı formations in these sections and isotopic dating. The Miocene succession in the study area begins with the upper levels of the Burdigalian-Serravallian aged Köselerli/Mut formations. Just above these levels, the Dağpazarı formation, which contains greenish, abundant Ostrea fossiliferous, silty-clay, lignite levels, is unconformably located. This formation includes the following ostacode types; Cyherella terguemi, C. glypta, Bairdia subdeltoidea, Neomonoceratina mouliana, Hemicyprideis sp., Cytheridea acuminata acuminata, Krithe monosteracensis, K. langhiana, Acanthocythereis hystrix, Cistacythereis caelatura, A. ulicznyi, Pokornyella deformis minor, Tenedocythere salebrosa, T. prava, Loxoconcha alata. In addition, the observed planktonic foraminifera species are; Globigerinoides trilobus, Glb. sacculifer, Glb. ruber, Orbulina bilobata, O. suturalis, O. universa. and this formation contains abundant echinoid spines, bryozoa, gastropods such as Terebralia at different levels and fish otolith. The formation is of late Serravallian-early Tortonian aged and reflects the shallow reef character that continued its development in the late Miocene. The formation consists of bulbous weathered, dark green claystone, Ostrea and Bairdia subdeltoidea, which are reduced in size at the levels that pass into hard clayey sandstone, abundant benthic foraminifera with abundant echinide spines. The formation consists of weathered, dark green claystone, Ostrea and Bairdia subdeltoidea, which decrease in size at the levels that pass into hard clayey sandstone, and benthic foraminifera rich with abundant echinide spines. The upper part of the succession ends with hard, silty, clayey limestone and light colored limestone bands. This level (Ballı/Tırtar formation), which is compatible with the Dağpazarı formation, points to the roof of a young reef formation in Tortonian. Ostracod species such as Bairdia subdeltoidea, Buntonia sublatissima dertonensis, Thalmannia hodgii, Aurila pigadiana, Aurila sp.,.B Bassiouni have been described. The limestones also contain abundant echinoid spines and benthic foraminifera. The ratio of 87Sr/86Sr analyzed from the carbonate sample obtained from the Dağpazarı formation is 0.708920. The age of the Dağpazarı formation was calculated as 8.7 Ma based on these isotope data.
