One of the important aquifers for geothermal purposes in the Netherlands is the Lower Cretaceous Vlieland Sandstone Formation (VSF). The VSF is deposited in a eustatic transgressive phase and has a dispersed distribution in the northern Netherlands, which is not very well understood. This study produced a depositional model and a thickness map for the VSF, based on available wells, biostratigraphy, cores and seismic data. The area of investigation is the northern part of the onshore Netherlands: Groningen, Friesland, Drenthe, the Wadden area. Regional tectonics and faulting determined the formation of the depocentres: the Vlieland and Lower Saxony basins. Subrosion and halokinetic effects in the Zechstein strata affected the paleogeography and influenced the deposition of VSF. In the early transgressional stage (Ryazanian, Valanginian), the basins are probably separated by the Friesland Platform, which is probably flooded during the Late Valanginian. Sandstones deposited at the end of the transgression (Hauterivian, Barremian) are found on the Friesland Platform and in the Lower Saxony Basin. Most VSF on the platform is reworked and the preserved sandstones represent mainly lower shoreface facies. This study shows that previous depositional models are outdated and comes up with a new depositional model and thickness map of the VSF.
