Fig. 6 in Foraminiferal Assemblages And Facies Associations In The Upper Jurassic Carbonates From Ardeu Unit (Metaliferi Mountains, Romania)

Fig. 6 Main facies associations of the carbonates from the Ardeu Unit. a Bio-oncoidal grainstone (F1) (Sample 48). Notice the thin rims of isopachus fibrous early cement bordering most of the bioclasts. b Bio-intraclastic grainsote/rudstone with Parurgonina caelinensis (P), Everticyclammina praekelleri (E) and Bacinella-type oncoids (B) (F1) (Sample 64). c Oncoidal wackestone/floatstone with numerous Bacinella-type oncoids, Thaumatoporella parvovesiculifera bridges and scarce foraminifera (F2) (Sample 5). d Bio-oncoidal floatstone with Rivularia-type cyanobacteria oncoids and Parurgonina caelinensis (F2) (Sample 23). Most of the oncoids are encrusted by Lithocodium aggregatum. e Coral-microbial-microencruster boundstone (F3) (Sample 183). f Brecciated bio-intraclastic grainstone with reef fragments (F4) (Sample 194). g Intraclastic rudstone (F5) (Sample 161). The intraclasts characterize different facies zones. h Intra-extra-bioclastic packstone/rudstone with different grain sorting and various intraclasts (F5) (Sample 160).
