Evaporates (gypsum and anhydrite):

The formation of evaporate was the most significant during the history of the Earth at the end of the Permian, after the formation of Variscan orogenesis lagoons and in epi-continental seas. The gypsum and anhydrite was formed by the evaporation of lagoons at arid climate. Gypsum and anhydrite is mainly used in the construction industry and for soil improvement. In Hungary it occures at Perkupa and Alsőtelekes. The upper-edge, the series of heavily creased gypsum-anhydrite contains serpentine-gabbros blocks and shale edges.
