Abstract

Studied zeolite bearing tuff from the Vetunica deposit is localized in northern marginal parts of the well known Kratovo-Zletovo volcanic area (Republic of Macedonia). Zeolite bearing tuff occupies the shallowest parts of the Tertiary volcanic rocks complex in this area. The stilbite (NaCa2Al5Si13O36 · 14H2O) was determined within the aforementioned zeolite bearing tuff. In our detailed study we found out that in the Vetunica deposit stilbite is present with 27%. Also, cation exchange capacity (CEC) and ammonium exchange capacity (AEC) values for samples from the Vetunica deposits are in the range of 94–102 meq/100 g for CECs and 109–114 meq/100 g for AECs. All the values show that these tuffs could be very effective in a wide range of applications such as waste water ammonium removal, in animal nutritions, fertilizers, fish farming, additives to cement and others. Geochemical data illustrates high concentrations >30 ppm As, 1 g/t Ag, 70 g/t Pb, 17 g/t B etc., as representative elements for this volcanic area.
