Turkish Journal of Earth Sciences

In the Aydıncık area, the Lower Liassic carbonates consist predominantly of dolomites, including limestone and dolomitic limestone intervals. These carbonates were deposited in peritidal environments, and later underwent early and late stage dolomitization. Petrographically, three dolomite-types are determined: (1) very fine to fine crystalline dolomite (T1) with crystal size of 13-65 µm and a good fabric preservation, (2) coarse crystalline sucrosic dolomite (T2) with size of 65 to 270 µm and fabric destruction, and (3) dolomite cement (T3) that occurs as a clear outer rim to cloudy coarse dolomite crystals (T2) or as a pore-lining and cement-fill of fenestral pores. …
