Finding traces of ultrahigh-pressure (UHP) metamorphism in the geological record has huge implications for unravelling Earth's geodynamic evolution, such as the onset of deep subduction. Usually, UHP rocks are identified by specific mineral inclusions like coesite and characteristic petrographic features resulting from its (partial) transformation to the lower-pressure polymorph quartz in thin sections of crystalline rocks. This approach relies on very small sample size and is thus limited to a ...[more]
