Les ouvertures minéralisées engendrées par la présence d'hétérogénéités. L'exemple du batholite du Sidobre et du champ filonien de Saint-Salvy (Tarn)

The Sidobre pluton was synkinematically emplaced on a dextral shear zone trending N 60 o . Hydrothermal fluids associated with the pluton were drained in zones of tectonic openings, due to the presence of heterogeneities, at all scales. The pluton, the aplitic dykes and the quartz lenses are heterogeneities created by the shearing deformation and were used by in to develop openings in which sulphides crystallized
