Thirty rock and mineral samples were collected in the Rabe-Bystre area in the so-called Bystre slice in the Flysch Carpathians. The research concentrated on the mineral occurrence, parageneses and on the relationship to the tectonics. Red mineral realgar displays a pure content of arsenic sulphide. It occurs in veins and aggregates in the most frequent association with quartz. Fluid inclusions in the realgar crystals have been characterized and preliminarily measured, which is a totally new study in the Carpathian area. A new mineral – goyazite SrAl3(PO4)(PO3OH)(OH)6 – has been found as intergrowths in the realgar accumulations, and its characteristics are provided. It seems that the quartz-carbonates-bitumen paragenesis in the study region is related to the distinct tectonic mélange zones, while the ore mineralization should be referred to fault zones and fissures, and/or the mélange zones. It has an epigenetic character, and may be referred to the adjacent potential magmatic body and mineralized waters in the neighbourhood.

Sulfate mineralization occurs in almost all lithostratigraphic beds of the Carpathians and has been described for at least the last century. While carrying out cartographic studies near Bobowa, a new site of gypsum mineralization was discovered within the hieroglyphic beds of the Jankowa anticline. The gypsum crystals found there reach up to several centimetres in length and, so far, no similar ones have been described in the Carpathian flysch deposits. Gypsum from Jankowa occurs in the form of intergrowth and twinnings, rosettes and larkspurs, and vein fillings.
