To describe particle size and sorting in dolostones, dolomite crystal size must be added to the modified Dunham terminology.

The entire columns are surrounded by bioclastic packstone to grainstone. The thrombolite-like mounds are domes a maximum of 100 cm high and 40-60 cm wide embedded within lime mud and shale.For the mB2 unit, class 2 wackestone and packstone were the main rocks of this reservoir unit when correlated with core description and microfacies thin section and the result was the same microfacies. The mB2 environment graded from mid-ram environments at the lower section to shoal and rudest bioherm at the upper section of the unit.

Packstone: Grain-supported muddy carbonate rock (Dunham, 1962). Lucia (1995) divides packstones into mud-dominated (pore spaces totally filled with mud) and grain-dominated (some intergrain pore space is free of mud) packstones. This division is important in understanding reservoir quality as mud plugs interparticle pore spaces.Download scientific diagram | Thin section of a packstone comprising Discocyclina and Operculina in a mud-rich matrix of the foraminiferal limestone facies.

Petrographic observations suggest that formation of moldic and vuggy porosity in this sample was controlled by multiple episodes of dissolution and infill of blocky calcite.Burrowed skeletal peloidal wackestone-packstone (LFA 4) This LFA consists of dark grey massive muddy carbonates (mostly wackestone and packstone). Carbonate constituents are predominantly skeletal grains including foraminifera, echinoids spines and bivalves; most are completely dissolved and preserved as moulds.

Red algae-bearing wackestone-packstone microfacies Red algae are abundant in the rock of the Yamama Formation. The most important of these algae species is the Permocalculus ssp. group, which is the main red algae group preserved as fossils, and most of the red algae belonging to this group are characterized by perforated skeletons.
