Formation of Sterksel

This layer shows the shallow appearance (up to 50 m below ground level) of the relevant mineral-bearing geological unit. This layer is an adaptation of the raster layer of the top of this geological unit, determines for the geological 3D model G3Dv3.1 (Deckers et al., 2019). The quality of minerals can vary within a geological unit. The shallow appearance at a certain place is therefore no guarantee that a good quality of the relevant mineral is found at that place.
