Environment/lithology: marine; poorly lithified, fine, medium, dolomitic, phosphatic, gray, argillaceous sandstone and lithified, dolomitic, phosphatic, gray, yellow, silty, sandy claystone

• Geology not specified for Peace River Formation.
• Composed of interbedded sands, clays and carbonates. The sands are generally light gray to olive gray, poorly consolidated, clayey, variably dolomitic, very fine to medium grained and phosphatic. The clays are yellowish gray to olive gray, poorly to moderately consolidated, sandy, silty, phosphatic and dolomitic. The carbonates are usually dolostone in the outcrop area. The dolostones are light gray to yellowish gray, poorly to well indurated, variably sandy and clayey, and phosphatic.
