Fig. 2: Reaction paths and structural evolution of pyrophyllite into its breakdown products in the ASH system.
From: A role for subducting clays in the water transportation into the Earth’s lower mantle
a The reaction path from pyrophyllite (solid line) is compared to that from kaolinite (dotted line) with their colors matching the formation depths. The reaction products from pyrophyllite and kaolinite are denoted by colored and white circles, respectively, while the other aluminoscilicate minerals within the ASH system are marked with gray symbols. b The structural evolution from pyrophyllite is shown in the order of the formation depths to illustrate the incorporation or release of H2O/SiO2 components (Supplementary Text 2).
