Historically, the bioclastic-packstone-to-grainstone facies would be interpreted as part of the “upper limestone” in the cyclothem model (Heckel, 1977). This definition has recently been clarified as a carbonate-dominated rock that does not contain any carbonate mud and where less than 10. 泥粒灰岩 ：就是灰岩中. The Massive A reservoir is 100Ð120 m thick and represented by uniform, bioturbated bioclastic packstone and bioclastic packstone-grainstone, deposited in a well-oxygenated, moderate to high-energy, shallow-marine environment. The Dunham system is based on depositional texture (that is, the amount of matrix surrounding the grains at the time of deposition). Rudstone. Skala foto 0,5 mm.

The wackestone to packstone and mudstone each constitute approximately one fifth of the reefs (22% and 21%, respectively) (Figs. 1993年，经全国科学技术名词审定委员会审定发布。. packstone As defined by the Dunham classification, a limestone characterized by a grain-supported texture, together with a lime-mud matrix. Grain-dominated packstone refers to the packstone whose inter-granular pore spaces are mainly open or filled with calcite cement whereas the pore spaces of mud-dominated packstone are filled mainly with mud (Lucia, 2007). The Upper Sinemurian, Pliensbachian and Lower Toarcian deposits of the Rodiles section are constituted by couplets of bioclastic lime mudstone to wackestone, occasionally. The bioclastic bed is composed of micritized bivalves and significant amounts of intraparticle calcite cement (stained pink) and pore spaces (white). Rudstone.

Grain-supported; carbonate mud matrix between skeletal grains (dasyclad algae, benthic foraminifers, bivalves) in interparticle pore space. There are four major microfacies recognized in the succession of the Shuaiba Formation, bioclastic mudstones. 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 in a mud-supported sediment); lime packstone (grain-supported limestone with mud matrix between the. Packstone contains lime mud in crude laminae or burrow mottles within dominantly grainy sediment or as mud infiltrated into intergranular porosity (Figure 7C). In addition, when we observe their Vp/Vs ratio with respect to their rock classes, we found that Dense Limestones tend to have the highest average. Klasifikasi Dunham (1962) punya kemudahan dan kesulitan. 1. The packstone has been extensively fractured, allowing for increased fluid flow. D'autres types de classification existent, en particulier la classification de Folk qui est plus complexe et plus détaillée, prenant en compte la nature du ciment (orthochèmes) et des éléments figurés.
