•Ignimbrite types and pumice have been obtained from Ahlat-Turkey.•g values obtained by EPR have been ascribed to ferric ions.•For pumice, amorphous property has been seen by XRD.•Crystalline structure of ignimbrites has been observed from XRD patterns.•SEM micrographs have been given.
Natural materials such as ignimbrites are preferred commonly not only in historical places but also in houses or in different kind of buildings all over the world especially around Ahlat in Bitlis-Turkey. Durability, lightness and good-insulation are the significative properties of these stones. Also, pumice is an another preferred material because of its advantages in construction industry. In this paper, four kinds of ignimbrite (light-yellow, yellow, black and white) and pumice from Ahlat region have been investigated by EPR method to determine magnetic properties of them. The results obtained by EPR, EDS and XRD methods are evaluated together. SEM technique is also used to understand the surface morphology of the samples.
