Přibyslavice near Čáslav, located in the NE edge of Moldanubicum, Czech Republic, is well known mineralogical locality supplying remarkable specimens of garnet, iron phosphates and nigerite. Remains of medieval tin mining were found here only recently. Ore-bearing quartz vein penetrated leucocratic muscovite-tourmaline orthogneiss. Small stock of fractionated tin-enriched muscovite granite and several types of pegmatite dykes crop out nearby. The ore vein is composed of smoky- and milky quartz, muscovite, tourmaline, fine-grained cassiterite with columbite inclusions and Ta-rich rutile. The muscovite granite contains disseminated cassiterite with columbite admixtures and nigerite. Similarity in chemical composition of cassiterite and columbite from the granite and from the ore veins support genetic link between the granite intrusion and vein ore mineralization.
