    The following types of calcified deposits characterize Holocene waterfall tufas in the Zrmanja river: mossy deposits, algally laminatedcrusts and algally coated grains. Petrological examination revealed,that abundant organic remains belonging to mosses and algae provide supporting material, over which tufa accretion takes place, leavingwell-defined impressions of the biota. Postgenetic features likemeniscus, isopachous and drusy mosaic calcite spar cementation, aswell as aggradational neomorphism are only rarely present.
