THE TOKAJ MOUNTAINS There are only a few outcrops of Paleozoic rocks known in these mountains in the neighbourhood of Vilyvitány. The quartz veins in these rocks are mineralogically the most interesting since their mineral assemblages contain not only albite, barite and pyrite but, occasionally honey yellow monazite-(Ce) grains. In quartz veins in the mica-schists in the vicinity of Felsőregmec there are some indications of the presence of copper and lead.

Typical of the main phase of crystallisation are the sizeable (several mm) crystals of plagio­clase, pyroxenes, and hornblende. Oxides, carbonates, and silicates of
