Hard rocks or crystalline rocks (ie, plutonic and metamorphic rocks) constitute the basement
of all continents, and are particularly exposed at the surface in the large shields of Africa …

Deformation along faults in the shallow crust (< 1 km) introduces permeability heterogeneity
and anisotropy, which has an important impact on processes such as regional groundwater …

Mountain water resources are considered to be the world's water towers. Still, despite their
importance for downstream societies and ecosystems and their vulnerability to climate …

Due to the duality in terms of (1) the groundwater flow field and (2) the discharge conditions,
flow patterns of karst aquifer systems are complex. Estimated aquifer parameters may differ …

This study presents a comparative, field-based hydrogeological characterization of
exhumed, inactive fault zones in low-porosity Triassic dolostones and limestones of the …

Crystalline-rock aquifers generally yield limited groundwater resources. However, some
highly productive aquifers may be encountered, typically near tectonic discontinuities. In this …

The origin of water flowing in faults and fractures at great depth is poorly known in crystalline
media. This paper describes a field study designed to characterize the geochemical …

While groundwater constitutes a crucial resource in many crystalline-rock regions
worldwide, well-yield conditions are highly variable and barely understood. Nevertheless, it …

Dissolved Oxygen (DO) plays a key role in reactive processes and microbial dynamics in the
critical zone. Recent observations showed that fractures can provide rapid pathways for …

Rock wall permafrost is highly sensitive to atmospheric warming. Its degradation is regarded
as a primary factor accounting for the recent increase in periglacial rock slope failures …
