Abstract: Below the Brussels Capital Region (Belgium) and the surrounding areas, Meso-Cenozoic soft sediments cover the hard and deformed Cambrian metasediments of the Brabant Massif. Traditionally, most of the existing shallow geothermal systems are installed in the sedimentary Mesozoic-Cenozoic cover, however, the depth of the Palaeozoic bedrock in this region (from 0 to 200 m) is adequate for the installation of both open- and closed-loop geothermal systems (Lagrou et al., 2019). Ongoing exploration drillings in Brussels demonstrated the high potential and efficiency of the Cambrian core of the Brabant Massif for geothermal systems. This high potential led to more feasibility studies for the exploitation of the Cambrian basement during the past years and more extensive research is currently conducted in the GeoCamb project with as aim to enhance the geothermal sector development and incorporate it in public buildings. Geological, hydrogeological and geophysical explorations are ongoing in public case-studies and several win-win cases. In this study we report on a multidisciplinary approach including many analyses conducted on lithology, mineralogy, and geophysical and thermal characteristics of the Cambrian basement and its weathered top.
