The mineralized veins and the impact of old mine workings on the environment at Segura, central Portugal

At Segura, granitic pegmatite veins with cassiterite and lepidolite, hydrothermal Sn-W quartz veins and Ba-Pb-Zn quartz veins intruded the Cambrian schist-metagraywacke complex and Hercynian granites. Cassiterite from Sn-W quartz veins is richer in Ti and poorer in Nb and Nb+Ta than cassiterite from...
