Abstract

WOLFRAMITE MINERALIZATION FROM THE VICINITY OF SZKLARSKA PORĘBA HUTA Summary In aplogranite from the vicinity of Szklarska Poręba Huta a wotframite mineralization was ascertained. Wolframite occurs in thin quartz veins together with molybdenite, cassiterite, sulphides of iron and copper and bismuth minerals. Besides this, wolframite forms crystals up to 2 cm in size in the minute druses in aplogranite. The named mineral association originated partly in the final pneumatolytic stage (405-375°C) and mainly during the hydrothermal stage (375-200°C).
