“…The anthropogenic influence of young floodplain deposits along German rivers was primary detected by Natermann (1941), Mensching (1951), Hövermann (1953), Hempel (1959), and, in Eastern Germany by Jäger (1962) and Händel (1969). This study is based on former investigations of other parts of the Mosel catchment in the Trier and the Saar regions (Weidenfeller, 1989; Weidenfeller et al, 1992, 2003; Zandstra, 1954) and, additionally, that of other river systems in Western Germany. Nearly all detected the main deposition periods during the young Holocene: Palatinate Forest (Stolz and Grunert, 2010), Westerwald and Taunus Mts (Stolz, 2011b; Stolz and Grunert, 2008), the middle Lahn valley (Urz, 2003), the Sieg valley (Heusch et al, 1996) and the Wetterau depression (Lang and Nolte, 1999).…”

This study deals with the exploration and spatiotemporal quantification of the young Holocene, nearly skeleton-free floodplain sediments of the Lieser River, a tributary of the Mosel River in the Eifel Mts. The deposits are primarily a consequence of anthropogenic-triggered soil erosion in the catchment. To observe the phenomenon of corresponding soil erosion on multiple levels two small alluvial fans of tributary catchments were investigated. For comparison, one location in the neighboring Salm valley was described. The results were compared with those of other streams. With extensive fieldwork more than 100 drillings and pits were made at 12 locations. For dating the sediments OSL dating, 14C dating of organic contents and archaeological artifacts were used. In the floodplains of the Lieser and its tributaries, 35.1 × 106 t of overbank fines are stored. To achieve this, an average soil erosion of 61.4 mm in the whole catchment would have been necessary. About 28% of young floodplain sediments in upper and lower course were deposited before ad 1000. However, prehistoric deposits could not be positively proven. Only 18% of floodplain sediments were deposited between ad 1000 and 1320 (early and high Middle Ages) and 54% during late Middle Ages and early Modern Time (ad 1320–1850), respectively. The thickness of floodplain sediments is mostly independent of the valley gradient. The largest sediment thickness (> 5 m) was found by drilling in the upper reaches. However, a part of this could be dated to the early Holocene. In the narrow middle reaches, the maximum thickness of the skeleton-free deposits was only 1.2–2 m. The average thickness of the floodplain sediments rose again in the depression of Wittlich up to 2.4 m. The formation of the investigated small fans was quite different. Sedimentation occurred within limited periods as a result of single events.

“…Evidence for drainage of the Buntsandstein is known in the Lower Sauer and Moselle valleys by ascending mineralized springs through faults even where the Buntsandstein is not directly exposed (Lucius 1953). A well productivity of 30 to 150 m 3 h −1 is observed in Lorraine (Agence de l'eau Rhin-Meuse 2002) and in the Saargau (Weidenfeller et al 2004). Average hydraulic conductivity in the South Eifel and Lorraine regions is practically the same and amounts to about 10 −5 to 5 × 10 −5 m s −1 (permeability of 1 to 5 D) (Celle-Jeanton et al 2009;LGB and LUWG 2010).…”

“…For the top of the Buntsandstein aquifer, additional depth maps by Coiffait and Ricour (1982) and Weiler (1972) were considered. Due to its appropriate depth and temperature and known excellent hydraulic properties (Agence de l'eau Rhin-Meuse 2002;Weiler 1972Weiler , 1991Weidenfeller et al 2004), the Buntsandstein aquifer is important for geothermal use and considered in more detail. The amount of geothermal energy extractable from a hydrothermal reservoir is a function of fluid properties such as temperature and mineralization, but achievable flow rates are crucial.…”

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.
