Abstract (in english)
   Dark carbonaceous cherts from the Blovice Formation (Kralupy-Zbraslav Group, Teplá-Barrandian Late Proterozoic) contain planktonic and benthic types of silicified microbiota, organo-sedimentary textures and structures and other evidence of locally preserved sequences which originated in near-shore, loittoral environment. Microfossils were studied in 200 thin sections, as palynological residua and by SEM rock-surface observation. Three successive generations of silicites can be distinguished, based on both mat-forming benthic and planktonic microfossils. Depositional environment includes subtidal shelves, oolitic limestones and silicified biostromes and presumed layered evaporites have been investigated. Agglomerations of coccoid, filamentous, colonial and vase-shaped microfossils are described
