G3Dv2_0312, drills with base Fm van Tielt

These are the observations made by the basis of the Tielt Fm, as defined in the Geological 3D model of the Flemish subsoil. These observations are mostly drilling, sometimes also slicing. The layer contains per drilling the depth of the base of the unit in metres compared to the start of the drilling. The Roerdalslenk was modelled using seismic data, correlated with 1 drilling. The Geological 3D model was drawn up under the Flemish Government’s management agreement with VITO, known as VLAKO, on behalf of the Department of LNE – Land and Soil Protection Division, Subsoil, Natural Resources.
