“…Both the present-day appearance of the TLE, in particular of the South Eifel region, as well as the development of the TLB were classically interpreted to be of practically identical origin and linked to the Eifel Depression (e.g., Lucius 1948;Murawski et al 1983;Wagner et al 2012). Already challenged by Weiler (1972), this interpretation has been questioned (Dittrich 1989;Schintgen and Förster 2013).…”

Background: The aim of this paper is to combine different types of information necessary for a first rather qualitative assessment of deep geothermal reservoirs in the region of Luxembourg. Within the geological framework, the study area encompasses Luxembourg and the surrounding areas of Belgium, Germany, and France. On the one hand, the focus is laid on low-enthalpy hydrothermal reservoirs in Mesozoic aquifers in the Trier-Luxembourg Embayment. On the other hand, petrothermal reservoirs in the Devonian basement of the Ardennes and Eifel regions are considered for exploitation by Enhanced/Engineered Geothermal Systems (EGS). Methods: For geothermal exploration and exploitation purposes, geological, thermal, hydrogeological and structural data are necessary. Results: Among the Mesozoic aquifers, the Buntsandstein aquifer characterized by temperatures of up to 50°C is a suitable hydrothermal reservoir that could be exploited by means of heat pumps or provide direct heat for various applications. The most promising area is the zone of the SE-Luxembourg Graben. The aquifer is the warmest underneath the upper Alzette valley and the limestone plateau in Lorraine, where the Buntsandstein aquifer lies below a thick Mesozoic cover. At the base of an inferred Rotliegend graben in the same area, temperatures of up to 75°C are expected. However, geological and hydraulic conditions are uncertain. In the Lower Devonian basement, thick sandstone-/quartzite-rich formations with temperatures >90°C are expected at depths >3.5 km and likely offer the possibility of direct heat use. The setting of the Südeifel (South Eifel) region, including the Müllerthal region near Echternach, as a tectonically active zone may offer the possibility of deep hydrothermal reservoirs in the fractured Lower Devonian basement. Based on recent data on the structure of the Trier-Luxembourg Basin, the new concept presents the Müllerthal-Südeifel Depression as a Cenozoic tectonic structure that is still mobile and relevant for geothermal exploration. Conslusion: Beyond direct use of geothermal heat, the expected modest temperatures at 5 km depth (about 120°C) and increased permeability by EGS in the quartzite-rich Lochkovian could prospectively enable combined geothermal heat production and power generation in Luxembourg and the western realm of the Eifel region.

“…According to Stets (2004b) and Dittrich (2011b), the WS was at least marginally incorporated during the formation of the TLB. However, as already mentioned, the structure and evolution of the TLB is classically assigned to the Weilerbach Mulde as a southwestern prolongation of the Eifel Depression (e.g., Lucius, 1948;Bintz et al, 1985;Murawski et al, 1983;Muller, 1987). The present-day appearance of the TLB as Gulf of Luxembourg is enhanced by the preferential preservation of the relatively resistant Luxembourg Sandstone framed by Triassic deposits in the northwest and east.…”

“…1), designated by the descriptive terms Gulf of Luxembourg (Golfe du Luxembourg respectively TrierLuxemburger Bucht) or Luxembourg Syncline (Synclinal du Luxembourg). As a subbasin of the German Triassic Basin in the early Triassic and a sub-basin of the Paris Basin since the late Triassic, the TLB progressively increased its spatial extension covering most of the older Variscan basement except the highest regions of the Ardennes in the northwest and the Rhenish Massif in the east (e.g., Lucius, 1937;Murawski et al, 1983;Dittrich, 1989).…”

“…prior to Dittrich 1989), the TLB is classically described to have a central Geology and basin structure of the Trier-Luxembourg Basin 3 syncline, the so named "Mulde von Weilerbach", forming the southwestern prolongation of the Eifel Depression ( Fig. 2; e.g., Lucius, 1948;Bintz et al, 1985;Murawski et al, 1983;Muller, 1987). Detailed observations, mostly in the widely exposed series of the Keuper, by Dittrich (1989Dittrich ( , 2011a and Dittrich et al (1997) describe a more complex setting leading to the rejection of the Weilerbach Mulde concept.…”

This paper presents the geology of the TrierLuxembourg Basin (TLB) in a comprehensive and updated manner. It describes the structural and lithological features of the basin, which comprises sediments of Permian to Mesozoic age. The regional geological assessment profited from recently published information on the geology and regional tectonics, as well as from borehole data from Luxembourg and adjoining areas in France, Belgium and Germany.The paper specifically focuses on the location of major synsedimentary faults and weakness zones, which gave rise to a new conceptual model of basin structure and evolution. The total depth of the basin as well as the thickness estimates of the fault-controlled subunits are supported by the interpretation of a Bouguer gravity map. In addition, the stratigraphy of the
