Multidisciplinary characterisation of fluid sources in ductile shear zones

2020
Ductile shear zones represent sites of significant fluid circulation and hydrothermal alteration where metamorphic, magmatic and surface-derived fluids meet. Characterization of the meteoric source of crustal fluids can be used to better understand ore deposition and mineralization at the orogen scale or for stable isotope paleoaltimetry ...

Anisotropic connectivity of the porous network in a ductile shear zone

1998
Porosity and connectivity of the porous network of a sheared granite in green schist facies, are showed by a capillary test under CT X-ray. A strong correlation is pointed out between mineral phases, strain (dissolution - crystallization, shearing), porosity and connectivity of the network.
