A study of the DeCew member of the Lockport Formation along 120 miles of the Niagara escarpment indicated, analogy to recent and ancient carbonate sediments that the unit was deposited in a shallow, subtidal, marine environment. The DeCew is characterized as a well-bedded, unfossiliferous, argillaceous dolomite, containing ripple marks, intraclastic zones, large scale contorted stratification and abundant ichnofauna.
