MARYLAND GEOLOGICAL SURVEY 137 posits are composed of clay, peat, sand, greensand, marl, gravel, iron ores,and ice-borne boulders. The topography of the region shows that the sur-face of the Coastal Plain is made up of five distinct systems of terraces,the oldest lying at the top and the others lying successively beneath in theorder of their age. The fifth terrace is now being built by the waves ofthe Atlantic ocean, the Chesapeake Ba}^, and estuaries. They are uncon-solidated except where locally oxide of iron, lime, silica, etc., has ce-mented the materials into thin ledges. The formations, beginning withthe oldest, are known as the Lafayette, Sunderland, Wicomico, Talbot,and Eecent. Each one of these formations corresponds to a distinct ter-race in the topography, the surface of the formation and the physiogra-phic feature of the terrace being one. It has been determined that theLafayette lies unconformably o
