Geology of Kızılkaya (Sevinçli / Aksaray) ignimbrite and investigation of the usage as building stone

28219

Aim of this study is to determine geologic, mineralogic-petrografhic features and investigation of the usage building stone of the Kızılkaya ignimbrite outcropping around the Sevinçli (Aksaray) Town. For this purpose the geology of Kızılkaya ignimbrite were defined and mineralogic-petrographic properties were determined the polarising microscope. In addition, in order to determine the physico-mechanical properties, physical and mechanical testes were carried out from Kızılkaya ignimbrite. Lower Pliocene Kızılkaya ignimbrite is acidic composition, welded tuff characteristic pyroclastic flow unit. The Unit is defined as vitric tuff and vitrophyric porphyric texture based on petrographic study. Ouartz and plagioclase are phenocrysts. Fine grained biotite, hornblend and very little pyroxsene minerals appears to be dispersed in volcanic glass. Volcanic glass shards are very common in matrix. As a experimental works, uniaxial compressive strength 9.81 MPa, flexural strength 4.06 MPa, compressive strength after frost 9.11 MPa, density 2.58 g/cm^3 was found. Considering the geology, mineralogical-petrographical examination, and the physico-mechanical properties of Kızılkaya ignimbrite, as a building material was found to be suitable for interior works in flooring.
