Los diques clásticos de Filón Norte (Tharsis). Interpretación en relación con la crisis finidevónica de la cuenca de la Faja Pirítica Ibérica

Basic rocks from the Filón Norte open pit (Tharsis, Iberian Pyrite Belt) are hydrothermally altered and crosscutted by a stockwork which is composed by carbonate filled veins and clastic dikes. Both, dykes and veins, show carbnonate selvages. Clastic dykes include black shale, basic rock and siliceo...
