Subsurface temperature model of the Swiss Plateau - elevation of the 60 °C isotherm

One of the main parameters used in assessing the geothermal potential of the Swiss Molasse Basin is the subsurface distribution of temperature. This map shows the elevation contours of the 60 °C isotherm and the faults at the same elevation. It is one of a set of maps that shows the distribution of temperature on selected surfaces representing seismic marker horizons, fixed depths below ground level or isotherms. The horizon surfaces are taken from the GeoMol15 geological 3D model and the temperatures from the GeoMol15 temperature model, which is composed of regular cells that are 1000x1000x100 m in size. This temperature block model is derived from a FE-method temperature model (Geowatt AG, 2015), which is based primarily on 31 vertical temperature profiles and the horizon surfaces from the <a href="https://www.geologieportal.ch/en/themes/fundamentals-of-geology/geophysics/seismic-atlas.html" target="_blank">Seismic Atlas of the Swiss Molasse Basin (2012)</a>. The FE temperature modelling method assumes conductive heat flow only and does not consider convective heat flow.
