Fluvial sedimentary styles and associated depositional environments in the buntsandstein west of river rhine in saar area and pfalz (F.R. Germany) and vosges (France)

Predictability of properties of a fractured geothermal reservoir: the opportunities and limitations of an outcrop analogue study

“…Within the Palatinate Forest, fluvial and aeolian facies alternate, whereas aeolian sediments are absent in the Odenwald (Hagdorn and Nitsch 2009). Since the unconformities that define the basic lithostratigraphic units of the Buntsandstein in the northern Germanic Basin are not clearly documented in the study area, distinction between the different units is difficult (Bourquin et al 2006;Dachroth 1985;Feist-Burkhardt et al 2008;Hagdorn and Nitsch 2009;Szurlies 2007). Further complications are introduced by the varying Buntsandstein thicknesses; they vary from about 60 m in the south of the graben to approximately 500 m around Karlsruhe, but further northward the thickness decreases again to about 300 m (Boigk and Schöneich 1970;Stober and Bucher 2014).…”

Synsedimentary faults and amalgamated unconformities: Insights from 3D-seismic and core analysis of the Lower Triassic Middle Buntsandstein, Ems Trough, north-western Germany

“…The resulting, dominantly continental facies of the German Buntsandstein (Grumbt 1974;Clemmensen 1979;Tietze 1982Tietze , 1997Dachroth 1985;Olsen 1988) aggravates detailed biostratigraphic subdivisions. Lithostratigraphic correlations, which are still preferentially applied to the units considered here, could be time transgressive and thus may provide limited information regarding facies and thickness variations across synsedimentary faults.…”

The complete lithostratigraphic section of the geothermal wells in Rittershoffen (Upper Rhine Graben, eastern France): a key for future geothermal wells

“…The Buntsandstein is subdivided into eight formations with thicknesses varying from 10 to 100 m. From the top to the base, these formations are the Grès à Voltzia and the Couches Intermédiaires in the Upper Buntsandstein, the Poudingue de Sainte Odile, the Couches de Karlstal, the Couches de Rehberg and the Couches de Trifels in the Middle Buntsandstein and the Grès d'Annweiler and the Grès Anté-Annweiler in the Lower Buntsandstein. Many works have been devoted to their thick detrital continental deposits (Perriaux, 1961;Gall, 1971Gall, , 1972Gall, , 1985Durand, 1978Durand, , 2010Dachroth, 1985;Mader, 1985 and many others). The greatest part of the Lower Triassic is mainly fluvial with some Aeolian episodes in the Karlstal formation (Durand, 1987).…”
