Abstract

Clinoptilolite and mordenite and other zeolite bearing altered ignimbritic rocks have been subject to petrophysical laboratory studies in which textural, magnetic, and electrical properties were investigated. Zeolite-poor and barren rocks also were included in the study. Preliminary results indicate that zeolite-rich rocks manifest: temperature dependent apparent porosities, low grain and dry bulk densities, generally low magnetic susceptibilities, a range of electrical resistivities — possibly reflecting degrees of silicification, and a tendency to low phase angles. The density and porosity data characterise zeolitic rock quite well; magnetic and electrical data are not diagnostic but do provide useful supplementary information on the likely or possible degree of zeolitisation.
