The results of mineralogical-geochemical investigations of Pežinske antimonite and
Chastyanske polymetallic deposits of Male Karpaty (Slovakia) are represented.
Crystalomorphological, mineragraphical, X-ray, thermobarogeochemical methods, the
microhardness measurements etc. were applied. In the samples from the antimonite
deposits antimonite, pyrite, pyrrhotite, gudmundite were studied. On the base of the
obtained results on the investigation of the mineral composition and textural-structural
analysis of sulphide mineralization and literature data the stages of minerals’ formation
processes, the corresponding paragenetic associations, different generations of antimonite
and pyrite are distinguished. In ore samples from polymetallic deposits the chalcopyrite,
sphalerite, galena, pyrite, pyrrhotite are described. On the results of mineragraphic and
paragenetic analyses of ores, and thermobarogeochemical analysis of inclusions in
sphalerite, quartz and carbonate the three stages of minerals’ formation processes are
revealed. The obtained results show that the process of formation of Pežinske and
Chastyanske hydrothermal deposits was pulsational and discrete.
Some ecological problems related to exploitation of ores are considered.
