Some ventifacts found near recent and fossil coastal dunes in Finland

Abstract

During the Holocene relative uplift of land in Finland coastal dunes were formed at various altitudes in areas earlier submerged. Some ventifacts found near these dunes, the oldest being about 4000 years old, are described from the Hanko (Hangö) peninsula and from Kalajoki in Ostrobothnia. The hard rock ventifacts have a shiny upper surface with no facets developed.
