Sep 28, 2021 · Silty carbonate contains mostly interparticle pores. The calcareous siltstones and silty mudstones contain a combination of organic matter pores and interparticle pores. Each of the rock types shows unique mineralogical compositions based on XRD. The mudstone lithofacies has the highest clay content and the least carbonate content. Shale is a sedimentary rock composed of fine-grained, compacted clay and silt particles. It often has a laminated appearance due to the alignment of mineral particles during its …The siltstone grades into shale in deeper water where the suspended clay particles are more abundantly deposited as the currents continue to lose energy. In either case, calm waters are needed for the suspension and sorting of silt and clay. Thus, sandstone, siltstone and shale are interrelated rocks that are distinguished by particle size.Parallel stratification in the silty shale at the top is probably a product of slow deposition of suspension materials under quiet water conditions. These silty shales are overlain by thin-bedded sandstone with scattered clay chips at the base, which were probably rapidly deposited. Locally, small-scale cut and fill structures are present (fig ...

Some common nonmineral constituent terms are: "tuffaceous," "cherty," "fossiliferous," "crinoidal," "coralline," "clayey (argillaceous)," "silty," "shaly," "sandy (arenaceous)," and "conglomeratic." Minor mineralogy should follow the nonmineral composition and should be restricted to one conspicuous mineral not implied in the root name.
clastic sedimentary rocks with predominance of silt and clay as the detrital components (Krumbein and Sloss, 1963). They are formed from silts and clays that have been deposited and compacted or hardened into rocks. On the basis of texture therefore, the most common types of shales are silty shale (silt dominant) and clay shale (clay dominant).
