Throughout the Paradox Basin, ... the phylloid algal facies consists of phylloid algal bioherms that vary in geometry from biostromal (flat and elongate) to a mound-like morphology with flat bases. ... The biostromal algal-rich beds were interpreted to have formed primarily through the hydrodynamic accumulation of phylloid algal plates in response to currents and wave action in water depths of 5-10 metres. The biostromal beds are characterized by a wackestone to packstone fabric with more interstitial mud and a lack of an interlocking fabric of algal plates ... characteristic of algal mounds.
