  • Ludovic Räss | Spontaneous formation of fluid escape pipes resolved in 3D Ludovic Räss | Spontaneous formation of fluid escape pipes resolved in 3D “Ubiquitous observations of channelised fluid flow in the form of pipes or chimney-like features in sedimentary sequences provide strong evidence for significant transient permeability-generation in the subsurface. Understanding the mechanisms ...
  • Daniel Kiss | Spontaneous generation of ductile shear zones by thermal softening Daniel Kiss | Spontaneous generation of ductile shear zones by thermal softeningThe spontaneous generation of shear zones in ductile rock is fundamental for many geodynamic processes, such as the initiation of subduction, the generation of strike slip zones or the formation ...
  • Joshua Vaughan-Hammon | Buoyancy-driven ascent of viscous bodies and associated strain Joshua Vaughan-Hammon | Buoyancy-driven ascent of viscous bodies and associated strainWe present two-dimensional numerical simulations of inclusions that are buoyantly rising in a matrix for linear and power-law viscous flow laws. We quantify the impact of: (1) effective viscosity ratio ...
