• Final Report Year: 2017

Final Report Abstract

Die Laser-ablations Ar/Ar Massenspektometeranlage wird einerseits zur Altersbestimmung von Proben im strukturell-texturellen Zusammenhang eingesetzt. Kalium-führenden Minerale paragenetischer Mineralassoziationen aus Mineralvergesellschaftungen unterschiedlicher Genese werden datiert, um die geodynamische Entwicklung einer Probe zu erfassen. Andererseits können mittels in situ Anaylsen an einzelnen Körnern Effekte von Argon-Überschuss und Argon-Diffusion erfasst und kartiert werden.
