Mineralogical and Chemical Characterization of Acidic Pumices Outcrop North of Lake Van

Abstract

In the present study, mineralogical, physical and chemical characteristics of the pumice located in North of Lake Van locations were investigated to find an applicability of them for cement and textile industry. Characterization studies of the pumice samples were carried out by thin section, SEM, XRF, XRD and FTIR analysis. In addition, the bulk density, Hard Grove Index (HGI), pozzolanic activity and reactive silica of the pumice samples were determined. The overall results showed that the pumice samples, which might be an eruption product of Mount Suphan, had an amorphous structure and rhyolite composition in high calcalkaline series. The chemical compositions and physical properties indicated that the pumice samples could be used in cement and textile industry.
