MINDeSEA WP4 Marine Minerals Phosphorites (Point)
In many places, marine phosphorites are accompanied by Fe-Mn crust mineralisations on the seafloor of continental shelves and slopes along the western continental margins of the Atlantic Ocean. They tend to occur in waters of medium depth. Some thick Fe-Mn crusts also contain carbonate fluorapatite, which was incorporated into the crusts during specific periods prior to middle Miocene during main Cenozoic episodes of phosphatization. These deposits are related to strong upwelling along the continental margins and seamounts. Marine phosphorites are known to concentrate rare earth elements and yttrium (REY) during early diagenetic formation. Although there are several references to ferromanganese crusts and their association with phosphorites in the literature, the genetic models for explaining their relationship and metal concentration are still poorly understood.

Characterise the deposit type (ferromanganese crusts or phophorites) by compiling relevant data on the classification, geological setting, terrain, age, mineralogical and chemical composition, morphology, textural types, and other controlling parameters. • Characterize the trace element content of the deposit type including Critical Raw Materials (CRM) for base, noble and technological metals. Study controlling factors on the occurrence of CRM. • Identify the principal metallogenic provinces where such deposits occur, taking into account spatial and temporal attributes, and provide models of formation. • Develop harmonized mineral maps and datasets of ferromanganese crusts and phosphorites incorporating GSO datasets (geophysics or samples geochemistry), along with mineral-potential and prospectivity maps. Settings and locations of marine minerals on the EU´s Critical Raw materials list. • Demonstrate how the case study results can be used in mineral exploration

Data Quality
Data modeling used D2.8.III.21 Data Specification on Mineral resources - Technical Guidelines to generate data schema for Ferro-manganese Crusts data produced by EMODnet Geology WP7 Minerals and MINDeSEA WP8 Link to Information Plaform for MINDeSEA WP4 Ferro-manganese crusts, phosphorites and Critical Raw Materials. The INSPIRE MineralResourcesCore UML class diagam applied for the spatial data attributes includes the following feature types: MineralOccurrence, Mine, MiningActivity, MineralDepositModel. The MINDeSEA WP4 applies the following tables: Chemistry, economic, environment, metallogeny, other and phosphoritesCriticalRawMaterials as agreed by the WP4 and WP8 leaders.
