Mineral chemistry (EPMA, LA-ICP-MS) of detrital scheelite from the Felbertal, Stubachtal and Hollersbachtal, Eastern Alps Mineralchemie (EPMA, LA-ICP-MS) von detritärem Scheelit aus dem Felbertal, Stubachtal und Hollersbachtal, Ostalpen Altenberger, Florian Geringer, Annika Werdenich, Manuel Weilbold, Julia Tungsten Mineral exploration Trace elements Critical raw materials Indicator minerals Stream sediments :550 As a part of the HeavyMin project, the regional tungsten potential of the Eastern Alps was investigated. The study is based mainly on tungsten enrichments documented during exploration activities in the 1970s and 1980s in different geological units of the Eastern Alps. The project objective is to assess potential tungsten showings based on characteristic mineralogical-geochemical datasets (“fingerprints”). The dataset includes mineralogical and geochemical investigations from three valleys in the Hohe Tauern region, including the Felbertal, which hosts one of the most significant tungsten deposits in Europe. The investigation focuses on scheelite (CaWO₄) - the dominant tungsten mineral in the Eastern Alps. Scheelite was characterized using a combination of cathodoluminescence imaging, electron probe microanalysis (EPMA), and in-situ laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The mineralogical-chemical results provide the basis for identifying characteristic tungsten fingerprints and assessing the tungsten potential. Im Rahmen des HeavyMin-Projekts wurde das regionale Wolframpotenzial der Ostalpen untersucht. Ausgangspunkt dafür sind vor allem die bei Explorationsarbeiten in den 1970er- und 1980er-Jahren dokumentierten Wolframanreicherungen in unterschiedlichen geologischen Einheiten der Ostalpen. Das Projekt zielt darauf ab, anhand charakteristischer mineralogisch-geochemischer Daten (Fingerabdrücke) potenzielle Wolframmineralisationen zu bewerten. Der Datensatz umfasst mineralogische und geochemische Untersuchungen aus drei Tälern der Hohen Tauern, darunter das Felbertal, in welchem eine der bedeutendsten Wolframlagerstätten Europas liegt. Im Fokus der Untersuchungen steht Scheelit (CaWO₄), das häufigste Wolframmineral der Ostalpen. Zur Charakterisierung von Scheelit wurden Kathodolumineszenzbildgebung, Elektronenstrahlmikroanalyse (EPMA) sowie in-situ-Laserablation gekoppelt mit induktiv gekoppelter Plasma-Massenspektrometrie (LA-ICP-MS) kombiniert. Die daraus gewonnenen mineralogisch-chemischen Signaturen bilden eine wesentliche Grundlage für die Identifizierung charakteristischer Wolfram-Fingerabdrücke und damit für die Bewertung des Wolframpotenzials. These published data are part of the project “Heavy Mineral Analysis as Indicators of Raw Material Types and Prospectivity with a Focus on Tungsten (HeavyMin)”, carried out as part of the exploration initiative of the Federal Ministry of Finance. The HeavyMin project presents a fundamental contribution to the exploration activity in Austria by systematically sampling heavy minerals from stream and glacial sediments in selected areas. The objective of the project is to collect mineralogical and geochemical data of indicator minerals. The series comprises a consistent dataset of mineralogical information on heavy mineral samples from various mountain streams in the Hohe Tauern region.
