Investigated area and its surrounding district consist of volcanic rocks. The Sanduklu volcanic are mainly composed of lavas, tuffs and tuffits. Using to K-Ar age method, the age of Sanduklu Lavas have been dated and ranged from 14 ± 0.3-8.0 to ± 0.6 Ma (Ercan, 1986).On the basis of diagrams Si02-(K20+Na20), Log (Zr/ TiO2*0.0001)-SiO2, Nb/Y-Log (Zr/TiO2*0.0001) and Ti02-Zr lavas are thrachyandesite, phonolitic tefrite, basaltic andésite, basaltic thrachy-nephelinite, andésite and dacite. Tuffs have been widely zeolitizated and dominant zeolite minerals are chabazite and phillipsite. Three phillipsite form were determined. These are potassiumsodium-aluminum-silicate hydrate, sodium-aluminum-silicate hydrate and potassium-calcium-silicate-silicate hydrate. The chemical and technological tests of zeolitic tuffs, altered lavas and tuffits were carried out and they are suitable to trass standards in cement industry.
