Polymetamorphism and polyphase deformation of the strata-bound magnesite-scheelite deposit, Tux-Lanersbach, Eastern Alps, Austria

The Tux-Lanersbach magnesite-scheelite deposit is one of several small strata-bound scheelite deposits (total ore reserves, 0.5 Mt at ca. 0.9% WO 3 ) situated in low-grade metamorphic lower Paleozoic sequences of the lower Austroalpine Innsbruck quartz phyllite zone. A polymetamorphic evolution of these volcano-sedimentary and sedimentary series is indicated by Ar-Ar dating. The dominant M 2 -D 2 event is of Eoalpine (Cretaceous) age and the...
