The skeletal grainstone under the MEH is Late Permian in age on the basis of Palaeofusulina. The Late Permian grainstone contains more than 80% (relative to the sediments) fossils, including rugose corals, fusulinids, calcareous algae, foraminifers, crinoids, bryozoans, brachiopods, and several other metazoan fossils.It formed as part of a giant ramp (asymmetric wavefield) within the intrashoal channel setting. AP-II, also a skeletal grainstone, is a complex of giant sandwaves that moved into the area under the infulence of a storm and partly filled the basal channel form of AP-I. Large avalanche foresets with tangential toesets prevail.@article{osti_1426171, title = {A method to generate small-scale, high-resolution sedimentary bedform architecture models representing realistic geologic facies}, author = {Meckel, T.

Enhanced porosity or permeability due to significant alterations resulting from subaerial exposure and hydrothermal dolomitization are also incorporated into the analysis as applicable.

At the top of the section, size grading of crinoid ossicles indicates turbulent current allowed significant sorting during deposition of the skeletal packstone–wackestone with intraclasts. boring-rich skeletal-grainstone horizon (solid curved band). McKenzie, 1998). The framework components of the thrombolitic fabric are thought to be calcified filaments of the green alga (Chlorophyta) Os-treobium sp., with clots formed by spores of the chlorophyte Acetabularia sp.

In the Lower Cambrian of southwest Sardinia, a carbonate platform developed, showing clearly different stages of evolution: (1) a homoclinal ramp containing algal-archaeocyathan mounds (consisting mainly of Epiphyton and Renalcis boundstone) in the west, clastic tidal flats in the east; (2) an ooid-pellet barrier ramp with ooid-shoals, prograding toward the west.Skeletal grainstone with primary interparticle (intergranular) porosity (blue epoxy), minor intraparticle (intragranular) porosity and scarce cementation.
