A brief review of the formation of coastal dunes is presented below. 1) Some ancient eolian sands are found only in the definite horizons of a Quaternary sequence; i. e., the Riss-Würm, late Würm, and later Holocene in age. 2) The deposition of some eolian sands is probably related with the fall in sea level. Others may indicate strong wind-action or arid climate. 3) The first appearance of the extensive emerged bars composed of the Quaternary marine and eolian sediments was probably due to the tectonic movement which generally produced an anticline. The Riss-Würm Interglacial transgression played the most important role in the development of the emerged sand bars where the eolian sands were deposited to conform closely to the pre-existing form of them.
