One of the most intriguing and (from the point of view of modeling) poorly understood
aspects of geomaterial mechanics is strain localization. Strain localization is a common …

Pore connectivity is a measure of the fraction of pore space (vesicles, voids or cracks) in a
material that is interconnected on the system length scale. Pore connectivity is …

The connectivity of rocks' porous structure and the presence of fractures influence the
transfer of fluids in the Earth's crust. Here, we employed laboratory experiments to measure …

Magma may fragment as it ascends through the volcanic plumbing system to the Earth
surface, forming volcanic ash and pyroclasts (Scheu and Dingwell 2022, this issue). If the …

Abstract 3D printing is an emerging technology which can provide valuable insights into the
laboratory characterization and testing of rock mechanics. The binder jetting technology …

Our multidisciplinary study aims to better understand the permeability of active volcanic
hydrothermal systems, a vital prerequisite for modelling and understanding their behaviour …

Hydrothermal fluids can alter the chemical and physical properties of the materials through
which they pass and can therefore modify the efficiency of fluid circulation. The role of …

The geometry of voids in porous rock falls between two end-members: very low aspect ratio
(the ratio of the minor to the major axis) microcracks and perfectly spherical pores with an …

Geothermal projects in the Upper Rhine Graben aim to harness thermal anomalies that have
arisen due to hydrothermal circulation within the granitic basement and the overlying Permo …

Sintered materials are used as permeable filters and flow controllers, for which a validated
and general model of porosity and permeability is required. Here, we prepare samples built …
