Blue minerals and blue rocks: From minerals to models
Friday 6 November 2020 16.00 – 17.15
William-Olssonsalen and by Zoom
Speaker: Paola Manzotti | Assistant professor, Tectonics, metamorphic petrology and geochronology"
Department of geological sciences, Stockholm University.
The blue amphibole glaucophane is considered as indicative of blueschist-facies metamorphism. However, blue amphiboles display a large range in chemical compositions. Therefore, the whole-rock composition strongly controls the stability field of the sodic amphiboles at the transition from greenschist- to blueschist-facies conditions. This talk explores (i) the mechanisms that control the development of sodic amphibole within the Dent Blanche Tectonic System (Alps), as a result of the Alpine metamorphic history and (ii) how the chemistry of the blue amphibole changes with pressure, temperature and oxidation conditions.
