Parageneses of mineralising events in the fracture network within the Buntsandstein Gp. sandstones. One paragenesis sequence is extracted for each structural sample context, e.g. deep-seated sandstones, and shoulder outcropping sandstones. In grey, the diagenetic sequence affecting the sandstone before deformation (e.g. first deformation bands); in blue, events affecting the deep-seated reservoirs and in pink the outcrops on URG shoulders.
