American Emerged Shorelines Compared with Levels of Australian Marine Terraces

Shorelines at 360, 70, and 25 ft above sea level in the Coastal Plain of the United States agree perfectly with levels in Victoria, Australia. Intermediate levels in Australia are somewhat lower than in America, possibly indicating that they are levels on the terraces rather than at the shorelines. This correlation shows that both the Coastal Plain and Victoria have been stable areas ever since early Pleistocene time; neither has changed level with respect to the other. It also corroborates my opinion that the higher terraces in the Coastal plain are Quaternary for in both regions the terraces transgress Pliocene and older deposits. Table 1 compares my interpretation which differs fundamentally with that of Ward, Ross, and Colquhoun.
