Las mineralizaciones estratoides de Zn-Pb de la serie de Vegadeo en la zona de Ponferrada (zona Astur Occidental Leonesa, NO de España)

Abstract

In relationship with the Cambrian limestones of the Ponferrada area three kinds of stratabound Zn-Pb ore deposits are formed in different epochs and conditions. They include diagenetic mineralizations in undisturbed limestones, probably late-diagenetic ones in relationship with a silicification of limestones in contact with shales and, fina/ly, breccias interpretated as their possible hercynian remobilization
