I have recently started a PhD looking at the structural and
metamorphic history of the Glenelg Inlier in NW Scotland.
As a recent graduate I am having a little difficulty in establishing
which plagioclase activity model to apply to the GADS geobarometer.
I am trying to apply GADS to a Diopside-Oligoclase symplectite in
equilibrium with garnet within a retrogressed eclogite (i.e. early
high-P Granulite overprint).
Please could someone aid me with an appropriate expression or, even
better, an idea of where I might get a fully worked example of
activity models.
Regards,
Craig Storey
