Abstract
The study of the influence of the main Hercynian tectonic phase, H1, o n the Zn-Pb mineralizations (attributed to an exhalative-sedimentary o rigin) in the Pierrefitte Palaeozoic series shows the presence of ante -and syn-kinematic hydrothermal parageneses, cataclasis of fragile sul phides and flow of ductile sulphides, and the use of schistosity and t hrust planes as structural control of the redeposition of remobilized mineralization. These observations suggest that the stratabound bodies in the Ordovician sequence were formed by remobilization of Devonian mineralizations, and were controlled by the thrust tectonics H1.
