In Romania the mountain soils are developed on unstratified parent materials such as recent deluviums-eluviums formed from direct weathering of the rocks, and on stratified parent materials, a clayey interglacial layer, covered by postglacial deposits. In the Central Europe soil parent materials are stratified, formed in cold periods by periglacial processes. There were identified and described three layers who differ by the rock fragments litology, texture, mineralogy and heavy metals content (Kleber, 1990, 1992, 1997); additional those layers could incorporate loess, by periglacial processes (Semmel, 1993). This study has shown a very close connection between the parent material litology and granulometry and the soil types developed on mountain areas. There were identified both monogenetic soils, developed in present day conditions (Humosiosols, Criptopodzols, Podzols, Prepodzols), and poligenetic soils, formed on stratified parent materials (Eutricambosols and Districambosols).
