This layer is a decision support map. Based on harmonized NLS3D model. Gaps following directly the national border may show areas, where a harmonization was not feasible.

The 3D depth model of the Entenschnabel region has been built during July 2018 to March 2019, as part of WP3 of the 3DGEO-EU project. It is a preliminary, generalized model that has been used as input for burial studies within the GARAH-project. The study area covers the Entenschnabel in the northwestern part of the German North Sea sector and the adjacent areas in Denmark and the Netherlands. The model is based on 8 seismically interpreted horizons.

Harmonized thickness maps of 3 cenozoic units derived from NLS3D (harmonized geological 3D model of deeper underground) along the borderregion between Lower Saxony (DE) and the Netherlands (NL). Gaps following directly the national border may show areas were a harmonization was not feasible.

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.

"Exploration in the Atlantic, Mediterranean, Baltic and Black Sea" refers to marine exploration of mineral accumulations, deposits, resources and reserves on the Atlantic. Mediterranean, Baltic and Black Sea seabed. The target for MINDeSEA WP 7 is (i) to create a new dataset on the distribution of the explored areas for submarine mineral resources in Europe; (ii) to propose recommendations for new unexplored areas; and (iii) to recommend pilot areas with high potential of discovering new submarine mineral resource mineral accumulations

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.
