Bridgeton formation has two distinct contemporaneous phases. They are here called Glassboro phase and Woodmansie phase. The Glassboro is better known and is developed in the southwest part of the state. It consists primarily of gravel and sand, arkose in many places. The Woodmansie phase occurs east and north of the Glassboro. It is not arkose and is without crystalline rock, shale, red sandstone, etc., of the Glassboro phase. It is more largely sand and is thinner. It was derived chiefly from the Miocene and Cohansey formations.
