Aquifers | Thermogis

ThermoGIS v2.3 shows the geothermal potential of 29 water-bearing layers or aquifers (reservoirs), five aggregate layers that consist of two or more aquifers ('period') and an overview layer covering all aquifers (see table below). The Nomenclature of the Deep Subsurface on the DinoLoket website provides more geological background on the aquifers.
