Hybrid carbonates, defined as the combinations of in situ abiotic, microbial, and skeletal precipitates, have changed with the biological and environmental conditions throughout geological history. After a long interval of dual-hybrid carbonates, the triple hybrid carbonates became predominant in the late Pennsylvanian and lasted until the Middle Triassic. The organic reefs of the upper ...sorted, skeletal packstone to floatstone interfingering with branching coralline red algae and rhodolithic rudstone layers.

(A) Skeletal packstone – wackestone with intraclasts from the central part …This microfacies has peloidal skeletal packstone to grainstone rudist attitudes, and floatstone and rudstone are considered the shoal environment facies. The grains are moderately sorted to well-sorted. The bioclasts of the shoal environments are bivalves, intraclasts, corals, green algae, echinoderms, and rudist shells.The observed lithofacies are (1) foraminiferal and skeletal debris wackestone-packstone, (2) coral float-stone-rudstone, and (3) algal and skeletal wackestone-packstone; and microfacies are (1 ...

Without an antagonist muscle pairing, there would be no way for the body t...The skeletal grainstone/packstone lithofacies (lithofacies 4) is composed of very fine skeletal grains with many peloidal grains and some very-fine quartz and fine ooid grains (figure 5). This lithofacies is greenish to dark yellowish-brown color, and contains variable amounts of relatively unabraded skeletal fragments. ….

The mound capping facies include a lower skeletal packstone–wackestone and an upper lagoon facies marlstone and black shale. Various algal colonies performed different roles in the formation of the mound. Komia colonies were the mound constructors that baffled higher energy currents and entrapped fine sediment.CurseForge is one of the biggest mod repositories in the world, serving communities like Minecraft, WoW, The Sims 4, and more.

The δ 13 C stratigraphic correlation between Dajiang and GSSP Meishan section suggest that the deposition from the skeletal packstone to the overlying microbialite at Dajiang may be not continuous (Figures 2, 5).If the limestone also contains a minor element such as skeletal fragments, then it is called a skeletal-oolitic limestone. Two of the most widely used classifications are those of Folk (1959,1962) and Dunham (1962). Both classifications subdivide limestone s primarily on the basis of matrix content. ixtlan Skeletal packstone with foraminifera (Rotalia and Nummulites on the left side), coralline red algae fragments and a bryozoan impregnated with glauconite (top centre).
