This web map service shows faults and structures of geological units of the seafloor originated earlier than 2,588 Ma from now (pre-Quaternary). The data were compiled by BGR from the EMODnet geology partner organisations in the EMODnet Geology project phases I, II and III between 2009 and 2019 and the International Geological Map of Europe and Adjacent Areas (Asch, 2005). The scale varies between 1:200 000 and 1:5 000 000
