WebThe PerucKorycany Formation contains sedimentary facies reflecting both meandering- and braided-river systems and shallow-marine systems. Differences in the three depositional settings did not cause distinctly different modifications of the framework compositions of the arenites. The sand from the fluvial systems is very mature (Qm98F0Lt2). Weblithic sandstone. a sandstone that has a more transitional composition and texture. ... a part of a rock body that has characteristics from which we can infer the depositional environment. two types of facies shifts. onlap and offlap. onlap sequence (facies shift) coarser sediments are covered by finer ones.
