HYDROTHERMAL REGIME OF QUARTZ VEINS FORMATION AT THE EPITHERMAL DEPOSITS
Keywords:
cathodoluminescence, vein quartz, trace elements, hydrothermal deposit, Neo-gene.Abstract
Cathodoluminescence is a convenient method in studying the evolution of mineral formations. We used it to study quartz veins from three hydrothermal deposits of the epithermal type: Berehivske ore field (Ukraine), deposit of Kavnyk (Romania) and Banská Štiavnica ore field (Slovakia). Cathodoluminescence in quartz occurs due to the presence of alkali metal impurities. The nature of the detected cathodoluminescence indicates the accumulation of trace elements in the stagnant sections of the veins. At the same time, flow zones do not have a cathodolumines-cence, which is proof of the infiltration regime of these zones in the veins.
