Uses of diatomites outcroping in Tahar-Guzeloz areas (Nevsehir) as industrial raw material

In this thesis study, uses as indusrial raw material of located within the late Miocene-Pliocene age vocanosedimantery units diatomites which are formed due to volcanism and outcropping in Tahar and Güzelöz (Nevşehir) areas were investigated. For this purpose, three stratigraphic sections were measured in the study area, one of these sections was measured in the Tahar area (TK), and the two sections were measured in the Güzelöz area (GÜ1 and GÜ2). On the collected samples from the measured sections; Amount of acid and water-insoluble matter, loss on ignition (950 °C), whiteness, particle size, pore size, pore volume, hidrometer, compaction, specific gravity, (%) total porosity, specific surface area, palynological analysis, pH, filtration rate, SEM, XRD and XRF analyzes were carried out at the General Directorate of Mineral Research and Exploration, Ankara (MTA), Soil Mechanics and Construction Materials Quality Control Laboratory, Adana (ZEMKA), Aksaray University, Engineering Faculty, Department of Geological Engineering, Geochemical Analysis Laboratory, Aksaray (JAL), Aksaray University, Scientific and Technological Research and Application Center, Aksaray (ASUBTAM) and Dokuz Eylül University, Engineering Faculty, Department of Geological Engineering Laboratory, İzmir. Analyses results of the three sections diatomites in the investigated area were determined as; amount of acid-insoluble matters; 74,20-84,20%, amount of water-insoluble matters; 99,80%, loss on ignition ratios (950 °C de); 8,18-22,82%, whitenesses; 80,45-84,79%, particle sizes; 0,7-209 µ , pore sizes; 1,448 e-03A–5,888 e-04A, pore volumes; 1,148 e-02–8,515 e-02 cc/g, specific gravities; 2,33–2,49 gr/cm3, total porosities; 57–60%, cumulative specific surface areas; 4,047 e+01–5,160 e+01 m2/g, pH; 5-7 (acit and neutral), filtration rates; 138–351 ml/dk, SiO2 contents; 38,16–67,77%. It was determined that, the samples are not contain palinological material and these generally formed from long and large diatom genus and species. The evaluation of the analyses results showed that, all of the three location's diatomites can not be used as construction material, carrier, mild abrasive and cleaner, isolution material. At the same time, determined that, the Güzelöz–1 and Tahar location's diatomites can not be used as a fill material. In addition, it was determined that, the subject diatomites can be used in the manufacture of silicate, and in percolator by the enrichment in terms SiO2 Also, Güzelöz-2 location's diatomites can be used as a fill material in the rubber and paper industry.
