“…Earlier studies on pegmatite at the Wolfsberg deposit were conducted by Göd (1989) and Niedermayr and Göd (1992) and are summarized below. The Wolfsberg deposit occurs within the northern limb of a WNW-ESE-striking anticline structure ('Wolfsberg anticline, ' Göd 1989) that dips ~ 60˚ to the NNE and was developed during regional deformation associated with the Alpine metamorphism (Fig. 1B).…”

“…Irrespective of host rock, pegmatite consists of quartz + feldspar + muscovite + spodumene and a range of other accessory minerals. The modal abundance of spodumene is higher in amphibolite-hosted pegmatite than in mica schist-hosted pegmatite, resulting in a ~ 0.5 wt.% higher Li 2 O wholerock composition (Göd 1989). As both pegmatite types are believed to have crystallized from the same highly fractionated melt, differences between them are attributable to melt reactivity with different host rocks and degree of metamorphic overprint resulting from different host rock competence (Göd 1989).…”

“…The Wolfsberg lithium deposit (Carinthia, Austria) is the third largest lithium pegmatite resource in Europe, with estimated resources (measured + indicated + inferred) of 12.88 Mt @ 1.0% Li 2 O (European Lithium Limited 2021). The deposit is part of the Austroalpine Unit Pegmatite Province (AUPP) in the Eastern Alps (Göd 1989;Knoll et al 2023).…”

“…Genetic models for pegmatite are debated. Göd (1989) and Mali (2004) proposed pegmatite formation by fractional crystallization from a larger parent pluton. However, in the absence of strong field evidence supporting a genetic relationship between plutons and pegmatite, several authors have suggested that pegmatite is the melt product of Al-rich metapelite during the Permian event (Thöni and Miller 2000;Habler et al 2007;Konzett et al 2018a;Knoll et al 2018Knoll et al , 2023.…”

The Wolfsberg lithium deposit in Austria is one of the largest Li-Cs-Ta pegmatite resources in Europe. The deposit is part of the Austroalpine Unit Pegmatite Province in the Eastern Alps that formed during the high-temperature, low-pressure Permian extensional event and was subsequently overprinted by Cretaceous eclogite-facies metamorphism during the Alpine orogeny. The two pegmatite types distinguished at the deposit, amphibolite hosted-(AHP) and mica schist hosted-(MHP) pegmatite, consist of quartz, albite, K-feldspar, muscovite and spodumene with accessory apatite, beryl and columbite. Both pegmatite types have similar peraluminous granitic compositions and element distribution patterns. However, the AHP contains higher Li and Cs concentrations. Both pegmatite types display LREE-enriched/HREE-depleted chondrite-normalized REY patterns that suggest derivation from partial melting of basement mica schist during the Permian HT/LP extensional event. The Alpine metamorphism more strongly affected the MHP relative to the AHP, resulting in recrystallization of primary assemblages by metamorphic assemblages with lower rare-metal concentrations, and development of a strong foliation, during which (re)mobilized elements (e.g., Li, Cs) were concentrated along localized shear zones. Recognition of element remobilization in MHP associated with metamorphic overprinting may bear important implications towards mineral exploration for Li-Cs-Ta pegmatite in other strongly metamorphosed terranes.
