Generally, the skeletal packstone is composed of shells and shell fragments set in a micritic calcitic groundmass and, in places, cemented with sparry calcite.Many skeletal packstone/wackestone intervals are overlain by oolitic grainstone/packstone. The skeletal packstone/wackestone facies is also intercalated with the dolomite, anhydrite, and peloid grainstone/packstone facies of the St. Louis Limestone, and the quartzose grainstone of the Ste. Genevieve Limestone (fig. 6). Interpretation

Lime muds dominate Cambrian-Ordovician ramps, with oolitic and skeletal packstone deposited in shoal environments and areally extensive thrombolite boundstone facies in the intrashelf basin settings (Pruss et al., 2010).
