The Hera Au–Pb–Zn–Ag deposit in the southeastern Cobar Basin of central New South Wales preserves calc-silicate veins and remnant sandstone/carbonate-hosted skarn within a reduced anchizonal Siluro-Devonian turbidite sequence. orebody distribution is controlled by long-lived, basin margin fault system, that has intersected sedimentary horizon dominated siliciclastic turbidite, with lesser grits...

The case study presented here deals with the Pb-Zn-Cu skarn ores hosted in Rosas Shear Zone (RSZ), a highly strained domain located external zone of Sardinian Variscan chain. RSZ is characterized by several tectonic slices Cambrian limestones within strongly folded and foliated Cambrian-Ordovician siliciclastic succession, intruded late granites mafic dykes. Based on geological mapping, structu...

The investigation of heterogeneous magma systems enhances the understanding differentiation and transfer processes in active volcanoes, thus constraining dynamics driving eruptions related hazard. Magma heterogeneity is generally preserved coeval juvenile products explosive eruptions, as it occurs Upper Pumice sequence, emplaced by last sub-Plinian eruption at Nisyros volcano (Greece). deposit ...
