Description
Early 2025, a series of new 2D reflection seismic lines were acquired in the Euregion Meuse-Rhine for the site investigation for Einstein Telescope. Along and nearby these lines, data of several boreholes recently drilled for the project became available. The sonic logs in these boreholes allow for tying the lithostratigraphic interpretations of the boreholes with the seismic lines. In addition, legacy borehole and outcrop data in the area were converted into time-domain to support the seismic interpretation. The seismic interpretation of horizons and faults is key input for the 3D geological model of the study area. The most important lithological transitions have been consistently interpreted. These are the base upper Frasnian, top Famennian, top Dinantian and base Cretaceous. Most of these horizons represent (local) unconformities.
