The 1:100 000 scale bedrock map data of the Geological Survey of Finland (GTK) include mate-rial produced during 1948-2007 for the needs of the mapping of mineral resources, for the sus-tainable exploitation of aggregate resources and for scientific research. These data include lithological information as polygons , bedrock observation points and drilling sites as well as es-sential tectonic observations, and information on lithological primary structures, ore minerals and metamorphic index minerals. Some 1:100 000 map sheets give both stratigraphical information as well as lithological data. An explanatory text accompanies most map sheets.
