    Description / Table of Contents: Zusammenfassung In Tørdal durchschneiden Granit-pegmatitische Gänge eine vulkano-sedimentäre Abfolge, die über einem älteren Gneis-Basement und einem jüngeren Granit, von dem die Gänge stammen, liegt. Positive Kovariation von Scandium, Lithium, Beryllium und Zinn, die sich im Zuge eines Prospektionsprogrammes auf Zinn ergaben, deuten auf eine mögliche Anreicherung von Scandium und Zinn während des Aufstieges pegmatitischer Phasen durch die vulkano-sedimentäre Abfolge hin. Ein Scandium-reicher Ixiolit in Assoziation mit Pyrochlor und Bazzit wird beschrieben, der aus einem Clea-velandit-Amazonit-Pegmatit stammt. Der Pegmatit bildet einen Teil eines größeren Netzwerkes von granit-pegmatischen Gängen. Eine Alteration von Ixiolit zu Pyrochlor tritt als spätmagmatisch-hydrothermales Ereignis auf.
    Notes: Summary In Tørdal granite pegmatite veins cut through a volcano-sedimentary sequence which overlies an older, gneissic basement and younger granite from which they originate. Positive co-variations of scandium, lithium, beryllium and tin, which were documented through a recent prospecting program for tin, indicate a possible enrichment of scandium and tin during the passage of the pegmatitic material through the volcanic sedimentary sequence. A description is given of scandium-rich ixiolite, (Ta,Nb,Sc,Sn,Fe,Mn,Ti)2O4 in association with pyrochlore, (Ca,Sc,Y,Sn,U)2(Ta,Nb,Ti)2O6(O,OH,F) and bazzite, Be3Sc2Si6O18 from a cleavelandite-amazonite pegmatite occurring as a part of a larger network of granitic pegmatite veins. Alteration from ixiolite to pyrochlore appears as a late magmatic-hydrothermal event.
