Short summary
Geological carbon sequestration using basalts provides a solution to mitigate the high CO2 concentration in the atmosphere. Due to the long timespan of the GCS, it is important to understand the long-term deformation of the reservoir rock. Here, we studied the creep of basalt with fluid presence. Our results show presence of fluid weakens the rock and promotes creep, while the composition only has a secondary effect and demonstrate that the governing creep mechanism is subcritical microcracking.

Here we introduce a new approach for analysing time-resolved 3D X-ray images tracking mineral changes in rocks. Using deep learning, we accurately identify and quantify the evolution of mineral components during reactions. The method demonstrates high precision in quantifying a metamorphic reaction, enabling accurate calculation of mineral growth rates and porosity changes. This showcases artificial intelligence's potential to enhance our understanding of Earth science processes.

Short summary
Hydraulic rock properties such as porosity and permeability are relevant factors that have an impact on groundwater resources, geological repositories and fossil fuel reservoirs. We investigate the influence of chemical compaction upon the porosity evolution in salt–biotite mixtures and related transport length scales by conducting laboratory experiments in combination with 4-D analysis. Our observations invite a renewed discussion of the effect of sheet silicates on chemical compaction.

Short summary
Using experiments that simulate deep tectonic interfaces, known as viscous shear zones, we found that these zones spontaneously develop periodic sheets of small pores. The presence of porous layers in deep rocks undergoing tectonic deformation is significant because it requires a change to the current model of how the Earth deforms. Emergent porous layers in viscous rocks will focus mineralising fluids and could lead to the seismic failure of rocks that are never supposed to have this occur.

Short summary
The competing modes of fault network development, including nucleation, propagation, and coalescence, influence the localization and connectivity of fracture networks and are thus critical influences on permeability. We distinguish between these modes of fracture development using in situ X-ray tomography triaxial compression experiments on crystalline rocks. The results underscore the importance of confining stress (burial depth) and fluids on fault network development.

Short summary
Short summary
We examine rocks from the middle crust to explore how fluids circulate and influence a rock’s response to larger-scale tectonic movements. A model is developed in which fluids deep in the Earth migrate to clusters of pores generated during those movements. We document how distinct pores form in a specific order in association with local changes in how quartz deforms. The porosity evolves out of the deformation, changing the rate the rock moved under tectonic forces.

We apply multi-range hyperspectral imaging on drill core material from a Kupferschiefer-type Cu–Ag deposit in Germany, mapping minerals such as iron oxides, kaolinite, sulfate, and carbonates at millimetre resolution and in a rapid, cost-efficient, and continuous manner to track hydrothermal fluid flow paths and vectors towards base metal deposits in sedimentary basins.

Short summary
The Campi Flegrei volcano in Italy displays hot fumarolic solfataras famous since Roman times. We use the solfataric mineralizations to investigate the local setting, evolution and geohazards. These provide information on hydrothermal activities that have been stable over the past 20 years. They reflect extreme conditions associated with the fluid overflow from subsurface and surface waters through a fracturing conduit. The solfataras are toxic and represent an extreme environment for life.

Short summary
The olivine carbonation reaction is volume increasing and could prevent further reaction by clogging the fluid pathways. This contradicts the observed fully carbonated outcrops in nature, but the mechanism behind this self-sustainability is poorly understood. Our study reveals that the stretching-induced fracturing and the dissolution channelization are mechanisms that could contribute to the sustainability of carbonation reactions. This study provides new insights on the olivine carbonation.
