  • The Geological Survey Ireland (GSI), as partner and Work Package 7 (Minerals) leader of EMODnet Geology Phase III, are compiling information on marine sapropel sites. EMODnet partners are submitting the spatial extent of mapped deposits and established information; here you can view data collated thus far. Need abstract information here.....

  • The Geological Survey Ireland (GSI), as partner and Work Package 7 (Minerals) leader of EMODnet Geology Phase III, are compiling information on marine hydrocarbon deposits. EMODnet partners are submitting the spatial extent of mapped deposits and established information; here you can view data collated thus far. Oil and gas deposits include information such as deposit type, deposit sub type, economic feasibility, scale, status, operator, block name, data provider, host rock, area, depth to resource, references and comments.

  • The GSI, as partner and Work Package 7 (Minerals) leader of EMODnet Geology Phase II, are compiling information on cobalt rich ferromanganese crusts. EMODnet partners are submitting the mapped extent of cobalt rich ferromanganese crusts and established information; here you can view data collated thus far. Cobalt rich ferromanganese crusts are metallic mineral deposits that often form at depths between 400 to 4000 metres, as thin layers on the flanks of seamounts and submarine volcanoes. The crusts accumulate when manganese, iron and trace metals including cobalt, copper, nickel and platinum dissolved in sea water are precipitated onto the volcanic substrate. Marine ferromanganese crust deposits are potential mineral resources that contain base metals and strategic and critical elements such as cooper (Cu), cobalt (Co), vanadium (V), nickel (Ni), titanium (Ti), platinum group elements (PGEs) or rare earth elements (REEs). Traditionally, marine precipitates are defined as: a) purely hydrogenetic when all constituents are derived from cold seawater, (b) diagenetic, when all constituents are derived from cold sediment pore water; and (c) hydrothermal when precipitation occurs in the vicinity of hydrothermal vent sites from fluids with temperatures higher than ambient bottom waters. Hydrogenetic Fe-Mn crusts occur throughout the global ocean on seamounts, ridges and plateaus, where currents have kept the rocks free of sediment for millions of years. Some ferromanganese (Fe-Mn) crusts exhibit a mixed origin, primarily either hydrothermal-hydrogenetic or hydrogenetic-diagenetic.

  • 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.

  • The GSI, as partner and Work Package 7 Minerals leader of EMODnet Geology Phase II, are compiling information on Polymetallic sulphides PMS. EMODnet partners are submitting mapped PMS locations and existing information, here you can view data collated thus far. The PMS information presented here are of mapped PMS locations. Also known as Volcanogenic Massive Sulfides (VMS), Seafloor Massive Sulfides (SMS) and Black Smokers, PMS are base metal sulfur-rich mineral deposits. They occur along the earth’s major tectonic belts at spreading centres, as well as in intraplate regions where islands and seamounts are formed.

  • The Geological Survey Ireland (GSI), as partner and Work Package 7 (Minerals) leader of EMODnet Geology Phase III, are compiling information on marine placer deposits. EMODnet partners are submitting the spatial extent of known deposits and established information; here you can view data collated thus far. The placer deposit information presented here are locations with concentrations of detrital heavy metallic minerals or gemstones. The occurrences of such deposits are generally limited to the continental shelf regions less than 120m deep.
