Abstract


PEGMATITE VEINS OFTHE REGION OF SZKLARSKA PORĘBA (KARKONOSZE·MNTS)

The author undertook geochemical and petrographical examinations of pegmatite veins from the region of Szklarska Poręba in the Karkonosze Mountains, in order to determine their trace elements and the forms of their concentrations. For comparisons sake, she carried out identical determinations in granites from three localities adjoining these pegmatites, as well as of the granite gneiss from the surrounding of the Karkonosze granite massif.

The author ascertained the occurrence of the following trace elements concentrated in the accessory minerals of the pegmatites, or diadochally entering into the crystalline lattices of the main or secondary minerals: Ag, As, Ba, :Be, Bd, Ce, Cu, Ge, In, La, Li, Mo, Nb, Pb, Sb, Sn, Sr, Ta, Th, Tl, W, Zn, Zr, U, Y, Yb.
