The knowledge of in situ stress is critical in safe and optimised extraction of minerals and energy resources. In situ stresses are either measured directly (e.g. overcoring) or estimated indirectly (e.g. borehole breakouts). Borehole breakout analys

We present the hypothesis that investigation of precursor mechanisms to large scale instabilities, that have so far been overlooked in geo-processes, is possible. These precursor processes are evident in multicomponent materials, such as granular mat

Onsager’s theory of linear irreversible thermodynamics has been successfully applied to explain findings from experiments. However, its application to multiphysics processes in deformable porous media is a non-trivial undertaking. This contribution

Paleocene deep-sea limestones from New Zealand contain densely packed micro-scale dissolution seams which potentially released carbon into the ocean that was previously thought to be stored, according to high-resolution multimodal X-ray microscopy.

Understanding the dehydration of gypsum is important for fluid-triggered earthquakes, and for its use in the construction industry. Here, x-ray scattering reveals that a small elastic load substantially accelerates dehydration kinetics, and is far mo

Abstract The formation of compaction bands in porous brittle rocks such as sandstones and carbonates has a significant impact on the localization mechanisms preceding earth and planetary surface instabilities such as earthquakes, landslides, and plat

This paper presents a combined experimental–analytical investigation of coal strain development under fluctuating applied hydrostatic stress. The laboratory setup mimics the isotropic volumetric compaction of coal under burial–uplift cycles in th

Quantitative characterisation through mineral liberation analysis is required for effective minerals processing in areas such as mineral deposits, tailings and reservoirs in industries for resources, environment and materials science. Current practic

Accurate multi-physics modelling is necessary to simulate and predict the long-term behaviour of subsurface porous rocks. Despite decades of modelling subsurface multi-physics processes in porous rocks, there are still considerable uncertainties and
