TURMALÍN Z LOUČNÉ NAD DESNOU

Pavel Novotný

Abstrakt

In the affluence of the "Tříramenný potok" mountain stream near Loučná nad Desnou (in the Hrubý Jeseník Mts.) occur blocks of biotite gneiss with tourmaline. Research of this tourmaline by X - ray powder methods indicates predominance of dravite over other varieties of tourmalines. Dravite forms prismatic crystals in segregations of quartz together with feldspars, muscovite, garnet and apatite.
