This belt contains 9 facies: bioclastic wackestone with pelagic bivalve and foraminifera (O1), coral boundstone (O2), marl with foraminifera (O3), bioclastic mudstone mudstone (O4), bioclastic floatstone
(O5), bioclastic packstone (O6), sandy bioclastic packstone (O7), bioclastic packstone to grainstone (O8) and bioclastic grainstone (O9) (Figs.
Cemented beds richer in large-size bioclasts are also found forming "aprons" around the reefs (coarser textures surrounding the buildups, i.e., rudstone and floatstone
Grainstone with graded bedding: a coarse-grained floatstone
with fine (diameter less than 0.5 cm) rounded lithoclasts grades upwards into pure, well-sorted, fine-grained grainstone.
Strata exposed at the study site were assigned to seven lithofacies based upon sedimentologic, paleontologic and petrographic characteristics: (A) Oolite, (B) Skeletal, (C) in situ Coral, (D) Coral Floatstone, (E) Cross-stratified Skeletal Grainstone, (F) Fenestral, and (G) Breccia.
Coral floatstone is primarily composed of adult rugose corals in an argillaceous matrix (Fig.
The archaeocyathan biodiversity in the Esla nappe is higher because the floatstone lithofacies surrounding the mounds records the presence of Polythalamia sp., and Okulitchicyathus valdorensis Perejon and Moreno-Eiris, 2003 (Debrenne and Zamarreno, 1970; Perejon and Moreno-Eiris, 2003).

The lower part of the unit (62.0-65.7 m) consists of interlayering argillaceous dolomicrite and dolomitized, litho-bioclastic floatstone
to argillaceous wackestone with frequent pyritized discontinuity surfaces.
This level is represented by hippuritids floatstone
with a matrix of intraclastic/grainstones that includes fragments of coralline, codiacean, gymnocodiacean and udoteacean algae, corals and very sparse calcisphaerulids.
Semblances, shape-makers and floatstones
are all concepts with which the reader will become familiar, as are the strange but transient castles in the air from where Cole has to identify suitable items to salvage.
hedei has also been recorded from the same formation at the northern coast of Pioneer Island from grey, greenish-grey and reddish ostracode and algal floatstones
, oolitic packstones, and marls with sandstone and siltstone interlayers (Matukhin et al.
Upsection, pure, micritic, thickly bedded limestones with abundant rudists (Toucasia and Requienia) forming biostromes and bioclastic floatstones
