Exploration-relevant sandstones of Valanginium in Lower Saxony 1 : 500 000 - Sandstone thickness
Description
The overview map shows the distribution of Valanginium (Lower Cretaceous) in the Lower Saxony Basin and shows in particular exploration-relevant sandstones and their properties. Regionally contiguous sandstones with a thickness of at least five metres are considered to be relevant for exploration. For these units, a potential as geothermally usable aquifers can be assumed, but this must be demonstrated on a site-specific basis in individual cases. Delimited from this, claystones, siltstones, clay-silt sandstones and light-weight sandstones are summarized on the overview map. Porosity, permeability and transmissivity of lithologies were not included in the mapping, but are reported as drilling-related parameters where available.
Data refer to the evaluation of geophysical borehole measurements as well as from the geological strata inventories.
