This paper presents depth maps for eight key horizons and seven thickness maps covering the onshore and offshore areas for the Late Permian to recent sedimentary section of the Netherlands. These maps, prepared in the context of a TNO regional mapping project, are supported by nine regional structural cross sections and a table summarizing the timing of tectonic activity from Carboniferous to recent. These new regional maps enable the delineation of various structural elements but also reveal the development of these elements through time with improved detail. Since the latest Carboniferous the tectonic setting of the Netherlands changed repeatedly. During successive tectonic phases several pre-existing structural elements were reactivated and new elements appeared. The various identified regional structural elements are grouped into six tectonically active periods: Late Carboniferous, Permian, Triassic, Late Jurassic, Late Cretaceous and Cenozoic. This study demonstrates that many ...

ABSTRACT In 2011, TNO-GDN concluded a 5 year geological mapping of the Netherlands Continental Shelf. In this project all public data from hydrocarbon exploration were used resulting in a major update of the dataset and a variety of deliverables available at www.NLOG.NL. The stratigraphy of more than 400 wells has been re-examined and amended where necessary. 2D and 3D seismic surveys were re-interpreted and new velocity models were used for time-depth conversion of the interpretations. This resulted in a structural model from base Zechstein to base Neogene. Also 30 reservoir intervals were added to the model. For the offshore area around 3800 faults were interpreted. The offshore faults where the first to be stored in a spatial fault database. Apart from detailed spatial information, all faults are also labelled with fault-kinematic-, geomechanic- and dimensional properties. This database will soon become publicly available. The uncertainty related to interpretation and data-processing has been evaluated. This resulted in maps showing the standard deviation for the depth of the main stratigraphic intervals. Based on these new subsurface mapping results a new unambiguous- and data-driven classification of structural elements is proposed that reflects the coupling between the different stratigraphic superpositions encountered and the complex tectonic evolution.
