Abstract

In this study, utilization of Tahar-Güzelöz (Nevşehir) diatomites occurring within the late Miocene- Pliocene age vocanosedimentary units which formed due to volcanism and outcropping in Tahar and Güzelöz (Nevşehir) areas were investigated. In the study area, three stratigraphic sections were measured, one of which was measured in the Tahar area (TK), and the two others were measured in the Güzelöz area (GÜ1 and GÜ2). Various physicomechanical, chemical, mineralogical and analytical methods were used on the samples. Analyses results of the diatomites in the investigated area were determined as follow; 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, none of the three location’s diatomites is suitable as construction material, carrier, mild abrasive and cleaner, isolution material. At the same time, determined that, the Tahar and Güzelöz–1 location’s diatomites can not be used as filler 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 SiO . Also, Güzelöz-2 location’s diatomites can be used as filler material in the rubber and paper industries.
