Evolving temperature field in a fossil subduction channel during the transition from subduction to collision (Tauern Window, Eastern Alps)
Groß, Philip; Pleuger, Jan; Handy, Mark R.; Germer, Marisa; John, Timm (Journal of Metamorphic Geology, 2020-10-12)We investigate the evolution of the three‐dimensional thermal structure of a palaeo‐subduction channel exposed in the Penninic units of the central Tauern Window (Eastern Alps). Structural and petrological observations ... -
Inter‐laboratory Characterisation of Apatite Reference Materials for Chlorine Isotope Analysis
Wudarska, Alicja; Słaby, Ewa; Wiedenbeck, Michael; Barnes, Jaime D.; Bonifacie, Magali; Sturchio, Neil C.; Bardoux, Gérard; Couffignal, Frédéric; Glodny, Johannes; Heraty, Linnea; John, Timm; Kusebauch, Christof; Mayanna, Sathish; Wilke, Franziska D. H.; Deput, Ewa (Geostandards and Geoanalytical Research, 2020-12-25)Here we report on a set of six apatite reference materials (chlorapatites MGMH#133648, TUBAF#38 and fluorapatites MGMH#128441A, TUBAF#37, 40, 50) which we have characterised for their chlorine isotope ratios; these RMs ... -
Measurement of crystallographic orientation of quartz crystal using Raman spectroscopy: application to entrapped inclusions
Zhong, Xin; Loges, Anselm; Roddatis, Vladimir; John, Timm (Contributions to Mineralogy and Petrology, 2021-10-15)Raman spectroscopy has been widely used in mineralogy and petrology for identifying mineral phases. Some recent applications of Raman spectroscopy involve measuring the residual pressure of mineral inclusions, such as ...
