The Vysoka Formation is a product of sedimentation on an extensive shallow sea carbonate ramp. The extremely shallow water restrained the activity of tidal currents, but did not impede the destructive activity of violent storms and tidal waves (tsunami). On the basis of detailed sedimentological, microfacial, geochemical, biostratigraphical and paleoecological analyses, the formation was divided into three divisions, in which five facial and fourteen microfacial types may be distinguished. Conodonts, foraminifers, starfish, brachiopods, calcareous sponges, molluscs and one of the richest associations of Anisian bryozoans were found in the formation. Synsedimentary deformation and event structures were identified.
