Environment:marine indet.
Geology comments: General for Pridoli: "The beginning of the Pridoli was marked by a deepening...[shallow Lsts succeeded by micritic Lsts and calc. shales]...Horny discerned two basic lithofacies in the Pridoli Fm., namely the 'marly' lithofacies formed by rhythmic sedimentation of dark micritic limestone alternating with dark calcareous shales, and the 'carbonate' lithofacies of highly fossiliferous, biosparitic Lsts. The boundary between the two units...is not sharp...Due to a gradual shallowing towards the top of the Pridoli, the area of carbonate sedimentation expanded in the upper part of the Pridoli Formation...and persisted into the lowermost Lochkovian..." [carbonate lithofacies overlies marly]
For this Community: "In Bohemia the Dubaria Comm. is concluded to inhabit a quiet, shallow water plain in about the BA 2-3 position...
