Parent Material of the EU and Adjacent Countries. The geological conditions have a large effect on the nature of a soil region. They influence relief and altitude of an area and determine the mineral and chemical composition and also the structure of the soils. Parent material affects the texture and the fertility of the soils as well as the supply of nutrients and has consequences on the land use, too. The map shows 18 rock complexes which are evaluated in respect of their effect on soil formation. Here it must be pointed out that soils are not formed on the rock itself but on weathering products mostly consisting of several layers and with numerous external components incorporated by redeposition.
