Exploration-relevant sandstones of the Valanginium in Lower Saxony 1: 500 000 — Document Points (WMS Service)

The overview map shows the distribution of the Valanginium (lower chalk) in the Lower Saxony Basin and presents in particular exploration-relevant sandstones and their properties. Regionally contiguous sandstones with a thickness of at least five metres are referred to as exploration relevant. For these units, a potential as geothermally usable aquifers can be presumed, which, however, must be demonstrated on a site-by-case basis. This is shown on the overview map of claystones, siltstones, clay-silty sandstones and low-powered sandstones. Porosity, permeability and transmissivity of lithologies have not been taken into account during mapping, but are indicated as drill-related parameters where available.
