Research Interests:

  • Development and improvement of micro-analytical techniques for isotope analysis in geological materials with a special emphasis on high-precision Laser-Ablation MC-ICP-MS and SIMS U-Th-Pb dating techniques.
  • Radiometric dating and the derivation of the duration of geological events and processes with a main focus on the orogenic and anorogenic formation and evolution of continental crust.
  • Petrochronology: Linking radiometric age information with metamorphic processes; analytical issues, theory and applications.

Current Projects:

  • Development of U-Th-Pb in-situ dating techniques (LA-MC-ICP-MS, SIMS, LASS) for xenotime.
  • Advancing the petrochronology of temperature-dominated metamorphic processes by testing and enhancing the consistency and reproducibility of accessory mineral in-situ U-Th-Pb dating and petrology. -> references
  • Development of a tool-box to understand the petrochronological evolution of metabasic rocks by combining petrology with in-situ U-Th-Pb geochronology. -> references
  • Petrochronology of hight temperature metamorphism; the age, duration and rates of metamorphic processes in the lower continental crust.
  • Geochronological and isotope geochemical aspects of the interaction of mantle and lower crustal processes in the Ivrea-Verbano Zone, Southern Alps, Italy. -> references
  • Geochronology and isotope geochemistry of pre-Variscan plutonism in the Austroalpine Ötztal-Stubai complex, Eastern Alps, Austria.
  • Modelling of isotope fractionation effects in geomaterials.
  • Other running projects (mainly geochronologically oriented) are located in Thailand, Carpathians, Cameroon, Turkey, ...
