RHINE GRABEN

Fluid circulation at fractured basement/cover unconformity is of first importance for geothermal energy exploitation especially in continental rifting as the Upper Rhine Graben. This unconformity presents lot of natural fractures which constitute a large permeable fracture network driving brine movement. That constitutes a reservoir of hot water, which is exploited by several geothermal power p...

Geothermal projects in the Upper Rhine Graben aim to harness thermal anomalies that have arisen due to hydrothermal circulation within the granitic basement and the overlying Permo-Triassic sedimentary units. We present here a systematic microstructural, mineralogical, and petrophysical characterisation of the lowermost unit of this Permo-Triassic sedimentary succession—the Buntsandstein—sample...

Historically, footprint-bearing localities in eastern and western North America and southern Thuringia and northern Bavaria have played pivotal roles in Triassic archosaur footprint research. In a nearly complete sequence of formations and footprint-horizons in the Moenkopi Group (U.S.A.), Newark Supergroup (U.S.A. and Canada), and Buntsandstein, Muschelkalk, and Keuper groups (Olenekian to Nor...
