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.
