DOORNENBAL 1 TNO-NITG Netherlands Institute of Applied Geoscience-National Geological Survey Department of Geo-Energy PO Box 80015 3508 TA Utrecht The Netherlands Introduction The regional subsurface onshore mapping project of the "Geological Atlas of the subsurface of the Netherlands" was started in 1985 at the former Geological Survey of the Netherlands. This project is carried out with seismic and well data. It is now in its final stage. For this project regional depth and isopach maps are created (scale 1:250.000). The mapped intervals comprise eight major lithostratigraphic units in the range of
