Electron diffraction determination of 11.5 Å and HySo structures: Candidate water carriers to the Upper Mantle

We applied here a cutting-edge analytical approach to characterize the experimental rocks synthesized at the high pressures and temperatures matching with deep subduction conditions in the upper mantle. Fast electron diffraction tomography and high-resolution synchrotron X‑ray diffraction allowed the identification and the successful structure solution of two new hydrous phases formed as dehydration product of chlorite.
