Reconstructing Paleofluid Circulation at the Hercynian Basement/Mesozoic Sedimentary Cover Interface in the Upper Rhine Graben

Figure 3

Synthesis of main brittle tectonic phases and associated fracture set directions since the Hercynian orogenesis in the Rhine graben and around the area modified after [117, 118] based on [37, 45, 48]. The circles represent the main orientation of fractures related to main stress axis (north on the top, east on the right).
