Skeletal packstone
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). Small mounds of lime mud with algae, sponges, and stromatolites were located towards the edges of wide shelves.Dolostone reservoir facies are restricted-marine mudstone to skeletal mudstone and pelletal wackestone or packstone. Northeast of the Nesson anticline, production is from oolitic to pisolitic packstone or grainstone buildups in the Rival subinterval and from restricted-marine, dolomitized spiculitic mudstone in the Midale subinterval (base of ...
