It is common to use synthetic fibers to increase the strength of engineering materials. Fibers obtained from rocks have also started to take their place in composite applications together with glass and carbon fibers. The suitability of Central Anatolian volcanic rocks for continuous fiber production is particularly interesting for the commercial sector desiring to invest in the material. In this study, geochemical data of 171 Central Anatolian volcanic rocks from different volcanic centers were used to calculate four different acidity and viscosity coefficients/modules, and a large dataset was evaluated with factor analysis as statistical data reduction method. The Central Anatolian volcanic rocks were compared with five reference rocks from Russia, Georgia and Ukraine. Their normative magnetite contents and viscosities at 1450 degrees C were calculated to determine whether the samples can be considered suitable for fiber production and whether they could provide melt stream stability during production. Some basic and intermediate volcanic rocks from the Sivas, Mt Erciyes, Mt Hasan and Obruk-Zengen regions have the potential to produce staple and continuous fibers.
