In the Lower Palaeozoic rocks of the Brabant Massif (Belgium), a recently discovered polysulphide mineralisation is intimately related to a high strain zone. Data from drillings, completed with outcrop data allow a detailed investigation of mineralisation, alteration and fluid characteristics of this high strain zone, currently interpreted as a low-angle reverse shear zone and attributed to the main Early to early Middle Devonian Acadian deformation event. Ore mineralisation occurred synkinematically and was closely associated with the shear zone. I,ow saline H2O-CO2(-CH4)-NaCl fluids with temperatures gt 260 degrees C were involved in the hydrothermal circulation, which caused alteration of the host rock and extensive sericidsation in the shear zone. Isotope data and the general setting indicate a metamorphic-driven system.
