Description	Most provenance studies based on the Gazzi-Dickinson method of detrital mode analysis indicate that the flysch siliciclastics of the Nízký Jeseník Mts. (Lower Viséan to lowermost Namurian) have recycled orogen to dissected-arc provenance, but distinct stratigraphic shifts in sandstone composition were traced between individual formations. This provenance study reveals a distinct stratigraphic trend in sandstone composition in one of the flysch formations in the Nízký Jeseník Mts., the Moravice Formation of Upper Viséan age.
