We have published in collaboration with Erik Duesterhoeft from the CAU University Kiel a paper in the Journal of Metamorphic Geology describing a new hybrid modelling strategy for thermobarometry applicable to metamorphic rocks. This contribution describes a mutually consistent strategy based on quantitative compositional mapping and the software solution Bingo-Antidote integrated in XMapTools.
We show in this study that the interpretation of modelled mineral assemblages can be ambiguous in the presence of mineral relics that are predicted to be stable far away from their formation conditions. The phase(s) in disequilibrium can in theory be assessed from maps of quality factors for each mineral or statistically by combining LBC obtained from domains with variable mineral mode.
