Tracking slab surface temperatures with electrical conductivity of glaucophane [PDF]
Scientific Reports, 2021 AbstractSlab surface temperature is one of the key parameters that incur first-order changes in subduction dynamics. However, the current thermal models are based on empirical thermal parameters and do not accurately capture the complex pressure–temperature paths of the subducting slab, prompting significant uncertainties on slab temperature ...
