The GSI, as partner and Work Package 7 (Minerals) leader of EMODnet Geology Phase II, are compiling information on the distribution of known marine aggregate deposits in European waters. EMODnet partners are submitting the spatial extent of mapped aggregate deposits and established information; here you can view data collated and harmonised thus far. The aggregate deposits presented here comprise near-shore deposits of non-metallic detrital minerals and calcium carbonate. They occur both on beaches and deeper seabed areas. Marine aggregate deposits are principally extracted for use in the construction industry. Concentrated into their present occurrences by hydrodynamic processes, aggregates may have originally been deposited by mechanisms such as river or glacial deposition.
