The association fauna of this microfacies is Rotalia, together with miliolids, Dendritina and Alveolinidae including Alveolina, Glomalveolina and Borelis in a packstone–grainstone fabric (Fig. 4d). In field observations, it includes thick-bedded light gray limestones.Locally, where there is a mixture of packstone-grainstone clasts and mudstone-wackestone clasts, the grainstone-packstone clasts are locally porous as well. Shale: Green shale occurs throughout the core as thin depositional layers and as later fracture filling sediment. Shale is commonly associated with stylolite development.Grainstone, algal packstone, algal wackestone, and foraminifera wackestone are porous rock types, and echinoderm wackestone and mudstone are nonporous rock types. The types of pore structure in the study area can be divided into four types. Type I has midhigh porosity and medium-high permeability due to its large throat, while type II has a ...Resedimented packstone (mainly bed types Cl3 and Cl4) is more abundant in Val Bracca than in Val Taleggio and is present all across the log. Packstone facies are mainly represented by bed type Cl2, in beds from 4 to 42 cm thick.

Mineralogically, the wackestone and wackestone-packstone lithofacies are composed of predominantly calcite while the mottled dolomite is composed mainly of dolomite mineral.The overlying bioclastic packstone-wackestone alternation facies studded with fragments of algal reef and stromatolitic limestone along with various fossil shells like bivalves, echinoids and gastropods, most of them are micritized, resembles its deposition under back-reef lagoonal environments during storm condition which is overlain by an ...The gypsiferous foraminiferal packstone facies stratigraphically occupies the top position of the Harudi Formation and is a 0.74 m-thick brownish grey colour packstone that shows a high content of foraminifera, mainly Nummulites and Discocyclina, and low content of impure micritic carbonates besides secondarily precipitated gypsum and iron ...Chalky packstone is also found in this flow unit, but its tortuosity is quite high which can reduce permeability. Flow unit 3 is packstone–grainstone which are highly cemented, this decreases porosity and permeability significantly. These characterisations are summarised in table 2.packstone/grainstones, arenaceous mudstones and wackestones, coral/bryozoan framestones, and calcareous quartz arenites to sublithic arenites. In outcrop, the West Canyon Limestone conformably overlies the Upper Mississippian Manning Canyon Formation (referred to as Manning Canyon Shale by various workers; see figs. 2 and 3).The thick-bedded limestone, characterized by Alveolina packstone with abundant milliods (MF4, Fig. S2g) and rotalids (MF5, Fig. S2h), is interpreted as a restricted-lagoon deposit. A similar environmental evolution is recorded in other Himalayan sections, where the nodular limestone and the thick-bedded limestone are invariably separated by …Textures are dominantly packstone, but range from wackestone. Benthic foraminifers are common and include miliolids (Fig. 4K). Other common bioclasts constituents include bivalve fragments.Rocheville limestone (Figure 1c) (Middle Jurassic, Bathonian), is an oolithic packstone to wackestone (Dunham 1962), extracted in Villaines-en-Duesmois, France.
