MINDeSEA WP5 Marine Placer Deposits (Area)
Marine placer deposits have received much attention during marine exploration. They comprise detrital heavy metallic minerals and gemstones, eroded from, usually igneous, source rocks on land and transported to sea, mostly by rivers. Thereby placer deposits are concentrated by water motions (waves, tides, currents). The most important of these minerals, from an economical aspect, are: cassiterite (tin), ilmenite and rutile (titanium), zircon (zirconium), chromite (chromium), monazite (thorium), magnetite (iron), gold; the principle gemstone is diamond (Harben & Bates 1990). According to Daesslé and Fischer (2013) about 75% of the world’s tin, 11% of gold, and 13% of platinum are extracted from placers (Baker et al. 2014). Marine placer occurrences can be classified taking into account various factors.

One of the main objectives of the MINDeSEA project is to compile fragmented marine data products and metadata on areas explored and investigated for marine placer deposits and make them available through an information platform. The portal will provide access to data and metadata held by each organisation based on standards developed in the Geo-Seas (www.geo-seas.eu) and EMODnet-Geology (www.emodnet-geology.eu) projects and data products compiled at a scale of 1:250,000 (Phase 2), 1:100.000 (Phase 3) and more detailed scale when possible. We need to know and understand the location, extent and formation processes of marine placer deposits and how they are concentrated on the mineralization. It is necessary to identify areas with potential deposits as sources of the marine placer minerals within the EU and associated countries waters. The specific objectives of MINDeSEA WP5 will be: - Provide a systematic characterisation of marine placer deposits, by means of geological setting, sourcing, age, mineral content and other controlling factors. - Identify the main provinces where such deposits occur, taking into account spatial and temporal attributes, and provide models of formation. - Develop harmonised datasets and maps of marine placer deposits for the European seas, along with mineral-potential and prospectivity maps. - Establish synergy with on-shore RM research projects to use common standards and methodologies where applicable. - Analyse present-day status in terms of regulation, legislation and exploitation of placer deposits and demonstrate the efficiency of a pan-European research approach for mineral exploration.
