Abstract:
The caves with underground glaciations (multi-year or seasonal) represent by themselves one of the most interesting and distinct environments of cryominaragenesis. The main prerequisite of its broad occurence in caves is the elevated content of dissolved solids in cave water especially in the case of karst caves. Speleomineragenesis is a crystallization of the matter (formation of minerals) due to frosting of water solutions circulated in caves. The quantity and character of cryomineral components in cave ice depends first of all on lithological environment. In limestone caves different phases of calcite dominate, while in gypsum caves – gypsum, celestine, calcite and barite are typical. The admixtures are represented by allochthonic (mainly aerosols) and autochthonic particles. Cryomineral formations have a special (typical for them) micro-morphology allowing their identification. Cryomineral investigations are a new and interesting direction of cave mineralogy studies. There are also important for different reconstructions of cave environment, studying of chemical denudation etc.
