Lithology and environment
Primary lithology: lithified "limestone"
Lithology description: archaeocyath bioherms, 3 types: (1) isolated bioherms, 0.5-2.5 m in diameter and 0.3-0.7 m thick, (2) several bioherms form small patch reefs, 5-8 m thick and 10-20 m across, (3) massive composite bioherms, several m thick and more than 10 m long, bioherm complex 30-70 m thick. (From Laurie 1986): This formation name was proposed by Wells et al. (1967, p. 37) to define a sequence of thinly bedded calcareous sandstone, red-brown sandstone, siltstone and thinly interbedded dolostone overlain by pink and grey thick-bedded dolostone which crops out in the northeastern portion of the basin.
Environment:reef, buildup or bioherm
Geology comments: low-energy open shelf
