Eu isotope fractionation and hydrothermal alteration [PDF]
Scientific ReportsEuropium (Eu) has two naturally stable isotopes (151Eu and 153Eu). The Eu anomalies produced by feldspar crystallization during magma differentiation have provided valuable geochemical information for understanding the evolutionary history of magma in ...

Hydrothermal weakening and slope instability at Vulcano (Italy) analyzed using drones and in-situ strength measurements [PDF]
Communications Earth & EnvironmentInstability at volcanic edifices poses significant hazards, yet the processes driving rock weakening, particularly on steep, eroding flanks, remain poorly understood due to limited accessibility.

Spectral characterisation of hydrothermal alteration associated with sediment-hosted Cu–Ag mineralisation in the central European Kupferschiefer [PDF]
Solid Earth, 2023 The analysis of hydrothermal alteration in exploration drill cores allows for fluid–rock interaction processes to be traced, for fluid flow paths to be identified, and thus for vectors in mineral systems to be determined. Hyperspectral imaging techniques
