Piedrasluengas Peloids, micropeloids, Biostrome development oncoids, rugosans, above oolitic grainstone, chaetetids, Thartharella, in shallow carbonate Tubiphytes, beresellids, platform.
They built biostromes associated with rugose corals and chaetetids (Piedras Luengas Section, Minwegen, 2001) and built reefal structures associated also with rugose corals and chaetetids (Playa de la Huelga Section, Minwegen 2001; Bahamonde, 2008).
A progressive deepening during the Middle Oxfordian led to the general development of sponge facies, characterized by microbiolite build-ups interbedded with biostromes
Biostromes (life layers) are bioconstructions like mounds, but with a tabular f orm.
Uncommon carbonate buildups are small isolated reefs, mounds, and biostromes (Kopaska-Merkel and Haywick, 2001).
Basal Smackover strata in Alabama contain bioherms and biostromes that formed in shallow water, especially in the southeastern Manila and northern Conecuh embayments (Kopaska-Merkel, 1994, 1998a).
Composition, structure and environmental setting of Silurian bioherms and biostromes
in northern Europe.
Lower Carboniferous serpulid patch reefs, bioherms and biostromes
Carbonate clast-supported breccia lithofacies containing algal biostromes
, bryozoans, stromatoporoids and large coral reef fragments, become more important toward the top of the formation.
Upsection, pure, micritic, thickly bedded limestones with abundant rudists (Toucasia and Requienia) forming biostromes
and bioclastic floatstones prevail (Figs.
At Carrasqueira, for example, Beds 'K' and 'L' are dolomitic and while they contain quite amazing biostromes
of Radiolites peroni they contain few, if any, stratigraphically useful foraminifera.
