Bioclastic sandy packstone is composed of grey-to-greenish-grey thin-to-medium beds with the thickness of 20–30 cm, which are only observed in the Aghband outcrop section. The most constituent grains of the facies include fragments of pelagic foraminifers, ostracods, bivalve as well as some glauconites and phosphates.Further, the depositional realm of packstone facies was restricted to shelf lagoons when skeletal debris was derived from nearly shoal areas or reefs to the shallow environment (Harris 2009). The presence of broken skeletal component and planner stratifications reflect high-intensity tidal flows and wave activities in the present case.

The Kangan Formation is mainly limy (mostly packstone and grainstone) to dolomite-limestone and dolomite to calcareous-dolomite which is sometimes associated with the anhydrite layers. Previous studies on the Kangan Formation determined the lower (K2) and upper (K1) units of this formation (Insalaco et al., 2006), as shown in Fig. 1.Bioclastic packstone. The main components of this microfacies are represented by fragments of bivalves, green algae, coral, benthic foraminifers, especially fragments of orbitolinids, echinoids, and spicules of sponge (Fig. 5f).
