The Neves Corvo Cu-Zn-Pb(-Sn) deposit (Portugal) is one of the largest volcanogenic massive sulfide deposits (VMS) worldwide, hosted by Upper Devonian to Early Carboniferous rocks. Originally, it contained an early structurally controlled tin orebody (stockwork and massive cassiterite), which has now been mined out. In this study, we report the first occurrence of phosphate minerals (apatite, florencite, and xenotime) within t...

New inorganic and organic geochemical data from thucholite in the Upper Permian (Wuchiapingian) Kupferschiefer (T1) shale collected at the Polkowice-Sieroszowice Cu-Ag mine in Poland are presented. Thucholite, which forms spherical or granular clusters, appears scattered in the T1 dolomitic shale at the oxic-anoxic boundary occurring within the same shale member. The composition of thucholite concretions and the T1 shale diffe...
