Based on the integration of the outcrop data, biostratigraphic and microfacies information, Wargal Limestone is suggested toInduration refers to the thickening and hardening of soft tissues of the body, specifically the skin, and is the result of an inflammatory process caused by various triggering factors. Indurated areas commonly appear on the hands and face but can also be found on the chest, back, abdomen, breasts, or buttocks.The present study focuses on the depositional environment and the microfacies analysis of Yamama Formation. The results revealed several types of microfacies, including peloidal wackestone-packstone, algal wackestone-packstone, bioclastic wackestone-packstone, foraminiferal wackestone, bioclastic wackestone, and …

The studied crinoidal limestones are characterized by the following vertical trend: transition from single beds of unsorted wackestone/packstone appearing in the spiculites, through better sorted (grainstone beds), and finally to a homogenous thick complex of crinoidal grainstones being proximal tempestites (Fig. 2).

The diagnostic larger benthic foraminifera are recorded, which includes Nummulites mamillatus, Assilina spinosa, Assilina subspinosa ...The packstone sample contains mostly echinoderm ossicles, fragmented recrystallized shells of molluscs and marginally micritized fragments of Vermiporella sp. and less abundant other dasycladaceans such as Dasyporella sp., Moniliporella sp. and Mastopora sp. Type-II and type-III calcitarchs are abundant.Textures are dominantly packstone, but range from wackestone. Benthic foraminifers are common and include miliolids (Fig. 4K). Other common bioclasts constituents include bivalve fragments.

Since discoidal orbitolinids frequency is greater than the conical type, the orbitolinid packstone is addressed to low-energy environment (Schroeder et al. 2010) which is coincided with the shallow lagoon (Raspini 2012) below fair weather base zone (Flügel 2004). The angular bioclasts represent non-transported skeletal grain which attributed ...

packstone (pack biomicrite), wackestone (sparse biomicrite) and mudstone (micrite). Packstone and wackestone microfacies are formed in a relatively low energy environment because of the considerable proportion of carbonate mud in their textural framework (Dunham, 1962), while the mudstone microfacies settles out from suspension under quiet ...

If the carbonate is grain supported but contains a small percentage of mud, then it is known as a packstone. If the sediment is mud supported but contains more than 10 percent grains, then it is known as a wackestone, and if it contains less than 10 percent grains and is mud supported, it is known as a mudstone.

The sponge packstone is part of a lithologic change from carbonate-dominated Paratirolites Limestone to the overlying shale-dominated “Boundary Clay” (Leda et al., 2014; Gliwa et al., 2020). The sponge packstone itself does not show a change in depositional environment and thus reflects a continuation of its deep-water setting and …Dunham classification A widely used limestone classification, proposed by Robert Dunham in 1962, which divides limestones on the basis of their texture and mud content. For limestones which retain their original, depositional texture, the main subdivisions are: lime mudstone (limestone with less than 10% grains in a mud-supported sediment); lime wackestone (limestone with more than 10% grains ...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).Textures are dominantly packstone, but range from wackestone. Benthic foraminifers are common and include miliolids (Fig. 4K). Other common bioclasts constituents include bivalve fragments.d.

Porosity types were generally fine intercrystalline, vuggy and moldic. Figure 1. Open in new tab Download slide.

The occurrence of packstone is attributed to the infiltration of carbonate mud through the sediment during intervals of low energy, while the bioclast wackestone lithoclasts may be taken to indicate possible erosion of nearby penecontemporaneous sediment. A significant contrast between the oncoid grainstone microfacies and the cortoid-peloid ...

Bed 4, a packstone, was easily traceable across the quarry because of its high concentration of rugose corals and, along with Bed 3, was defined as the Rugosan Community (Frank unpubl. thesis 1981). The sharp basal contact of Bed 4 truncated a number of vertical burrows into which matrix from Bed 4 had passively filled.

In the grainstone-packstone middle interval (MGP), the internal lamination does not correspond to the planar lamination of the Tb Bouma division or to the parallel-lamination of the silty Td division; it consists of parallel lamination marked by recurrent changes in the size of the grains and in the proportion of the mud-rich matrix (Fig. 14 C).Condensed packstone of middle-upper Eocene, middle to inner ramp facies containing Nummulites, Discocyclina, Operculina, Actinocyclina (upper right) and Lithothamnium red algae oncoids (rhodoids).
