This study aims to investigate the industrial raw material potential of the Lower Liassic dolomites (Dibekli Member of Cehennemdere Formation) in the Aydincik (Mersin) area. The properties of Lower Liassic dolomites are based on the Pirencik Tepe, Erenler Tepe and Soguksu location measured stratigraphic sections. Mineralogical and chemical compositions of the dolomite samples were determined by petrographic, X-ray diffraction (XRD) and ICP-ES analyses. Petrographic examinations revealed the presence of three types of dolomites. These are: (1) very fine to fine crystalline dolomite (T1) with a size of predominantly 13-26 m, (2) coarse crystalline dolomite (T2) with a size of predominantly 65-130 m and (3) dolomite cement (T3). Among these, T1 and T2-type dolomites are widespread, and have importance as an industrial raw material. XRD analyses demonstrated that most samples contain predominantly dolomite, secondary calcite and accessory quartz minerals. ICP-ES analyses indicated that first type-dolomites (T1) have on average 20.76% MgO, 31.10% CaO, 1.59 % SiO2 + Al2O3 and second type-dolomites (T2) have on average 21.44 % MgO, 31.42 % CaO and 0.63 % SiO2 + Al2O3. These data indicate that the Lower Liassic dolomites can be utilized as raw materials in industry.
