Spectral characterisation of hydrothermal alteration associated with sediment-hosted Cu–Ag mineralisation in the central European Kupferschiefer [PDF]
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

Integration of support vector machines for hydrothermal alteration mapping using ASTER data – case study: the northwestern part of the Kerman Cenozoic Magmatic Arc, Iran [PDF]
This work applies support vector machine (SVM) algorithms in two versions of singular and general SVM classifiers to map hydrothermal alteration zones in the northwestern part of the Kerman Cenozoic Magmatic Arc (KCMA).

Geochemistry of Dorojen volcanic rocks (SW Ardestan) with the special use of mineral chemistry of Propylitic alteration zones [PDF]
Dorojin area in the Southwest of Ardestan city is part of the Urmia-Dokhtar magmatic zone. In the area of study, the intrusion of the Early Miocene granodiorite into the Middle-late Eocene sedimentary-volcanic complex caused the formation of hydrothermal

Hydrothermal Alteration of Glass to Chrysotile [PDF]
Chrysotile fibers were synthesized from glass in hydrothermal conditions. The starting materials were first held at 1650°C and then rapidly quenched down to room temperature. The resulting glass, after the addition of mineralizing agents, was hydrothermically altered in the following conditions: temperature 300 °
