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).
Other Bangor buildups in Alabama are coral biostromes, microbe-coral reefs, and bryozoan-microbial mounds.
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).
A progressive deepening during the Middle Oxfordian led to the general development of sponge facies, characterized by microbiolite build-ups interbedded with
biostromes. Relatively open marine conditions in the platform were restored at early Transversarium Chronozone (Parandieri to Luciaeformis subchronozones).
Composition, structure and environmental setting of Silurian bioherms and
biostromes in northern Europe.
Some smaller size patches or
biostromes have been observed during the episode C3, time-equivalent of the Marinella facies 5.
Lower Carboniferous serpulid patch reefs, bioherms and
biostromes. Nature, 242, 41-42.
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.
