Packstone
Wackestone. Under the Dunham classification (Dunham, 1962 [1]) system of limestones, a wackestone is defined as a mud-supported carbonate rock that contains greater than 10% grains. Most recently, this definition has been clarified as a carbonate-dominated rock in which the carbonate mud (<63 μm) component supports a fabric comprising 10% or ... A packstone is a rock with a grain-supported texture with the intergranular voids filled with a finer matrix. wackestone A lime wackestone is a matrix supported carbonate rock containing less than 75% mud-grade (<32 μm) calcite.

If the sediment is mud supported but contains more than 10 percent grains, then it is known as …Packstone and grainstone both consist mostly of carbonate grains, but differ in that packstone has a carbonate mud matrix while grainstone has carbonate cement between the grains. It is difficult to consistently distinguish between wackestone and packstone and is not important to make the distinction, so lump these two rock types together as ...Herein, in the El Djehaf analysed section, an oscillation between black to grey, organic-rich pelagic fractured wacke-packstone/black laminated mud-packstone and organic-poor light grey fractured well-bedded fine-grained, bioturbated mudstone-wackestone microfacies, is sedimentologically identified.Microfacies C—Bioclastic rotalia alveolinidae packstone–grainstone. 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.

This packstone, collected stratigraphically near the bottom of the bench in 1972, is well indurated (Fig. 7 C). Although mollusks are uncommon in the articulated crinoid layers, they are common in the packstone layers, are unabraded, and include delicate taxa such as weakly hinged articulated bivalves and thin-shelled gastropods (e.g ...Lithologies of this system include mudstone, siltstone, sandstone, conglomerate, diatomite, carbonate mudstone, wackestone, grainstone, packstone, and boundstone.
