• Incomplete Crack Sealing Causes Localization of Fracturing in Hydrothermal Quartz Veins 

      Späth, MichaelORCIDiD; Urai, Janos L.ORCIDiD; Nestler, BrittaORCIDiD (Geophysical Research Letters, 2022-08-10)
      Cyclic microfracturing and epitaxial crystal growth have long been recognized in crack‐seal veins, but an understanding of a single crack‐seal cycle is still missing. Here we present a phase‐field model that includes both ...
    • Kinematics of Crystal Growth in Single‐Seal Syntaxial Veins in Limestone ‐ A Phase‐Field Study 

      Späth, MichaelORCIDiD; Spruženiece, LieneORCIDiD; Urai, Janos L.ORCIDiD; Selzer, MichaelORCIDiD; Arndt, Max; Nestler, BrittaORCIDiD (Journal of Geophysical Research: Solid Earth, 2021-09-28)
      Building on recent developments in phase‐field modeling of structural diagenesis, we present an analysis of single‐seal syntaxial calcite vein microstructure in a variety of limestones. We focus on the effects of fracture ...
    • Quartz Cementation in Polycrystalline Sandstone: Insights From Phase-Field Simulations 

      Prajapati, NishantORCIDiD; Abad Gonzalez, Andres; Selzer, MichaelORCIDiD; Nestler, BrittaORCIDiD; Busch, BenjaminORCIDiD; Hilgers, ChristophORCIDiD (Journal of Geophysical Research: Solid Earth, 2020)
      Present work investigates the dynamics of polycrystalline quartz cement growth in sandstone using a multiphase-field model. First, the model parameters corresponding to common reservoir temperature and pressure conditions ...
