Our most recent paper presents a coupled geophysical-petrological model constrained by field data, showing that the apparent rate of transformation in the lower crust beneath the Himalayas fits very well the small-scale estimates. This is the first estimate over long time\u2010 and large spatial scales, demonstrating that regional metamorphic rates can be realistically upscaled for geodynamic modelling.
