• Experimental study of the evolution of fault gouge in layered sand–clay sequences 

      Schmatz, Joyce; Vrolijk, Peter; Urai, Janos L.ORCIDiD; Giese, Steffen; Ziegler, Martin; Zee, Wouter van der (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
      This study focuses on clay smear processes during fault gouge evolution in sand-clay sequences at depths up to 2 km. A clay-rich fault gouge can dramatically lower the fault’s permeability, and prediction of this process ...
    • Fossil overpressures compartments? A case study from the Eifel area and some general aspects 

      Hilgers, ChristophORCIDiD; Bücker, Carsten; Urai, Janos L.ORCIDiD (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
      Fluid overpressures are well known from hydrocarbon exploration in many sedimentary basins. They can reach almost lithostatic values, and may cause the fracturing of rock. Fracturing allows the discharge of fluid overpressure, ...
    • Microstructural analysis of the RWTH-1 cores in thinsections 

      Scholz, Katerina; Urai, Janos L.ORCIDiD; Trautwein, Ute; Kukla, Peter A.ORCIDiD (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
      The Aachen RWTH-1 well was drilled to 2544mTVD for geothermal purposes and gives substance to extensive geoscientific research. It is located in a hydrothermally and seismically active area of the Aachen Anticline, 500m ...
    • Microstructures of fibrous halite veins 

      Hilgers, ChristophORCIDiD; Pennock, Gill; Schléder, Zsolt; Burliga, Stansilaw; Urai, Janos L.ORCIDiD (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
      Halite veins hosted in clastic sedimentary rocks are frequently observed next to evaporite layers. Their microstructure can be enhanced by gamma irradiation and etching, which can be used to infer the deformation mechanism of ...
