Description It was named formerly mollusk packstone (Alkhaldi 2009) and massive peloidal skeletal packstone (Bashri et al. 2017).This is the basal facies encountered in the study N-S section of the Al-Lidam escarpment. The facies described from outcrops 1, 2, and 4 has increased skeletal components in outcrop 4 (Fig. 2).Skeletal packstone with foraminifera (Rotalia and Nummulites on the left side), coralline red algae fragments and a bryozoan impregnated with glauconite (top centre).

According to the Dunham classification, the Drunka Formation samples exhibit four main depositional textures: 1) lime-mudstone comprising mainly of micritic matrix and skeletal grains, 2) wackestone, indicating a lower proportion of skeletal grains found in the micritic groundmass, 3) packstone with a high abundance of skeletal and non-skeletal ...Representative photographs of massive skeletal packstone (F7).
