Dehydration of phengite inferred by electrical conductivity measurements: Implication for the high conductivity anomalies relevant to the subduction zones
Phengite is a critical carrier of water and potassium (K) in sediment as well as in the basaltic
layers of subducted slabs. However, although phengite dehydration can potentially be used …

Electrical conductivity of metasomatized lithology in subcontinental lithosphere
A plausible origin of the seismically observed mid-lithospheric discontinuity (MLD) in the
subcontinental lithosphere is mantle metasomatism. The metasomatized mantle is likely to …

Ab initio molecular dynamics investigation of the elastic properties of superionic under high temperature and pressure
Y He, S Sun, H Li - Physical Review B, 2021 - APS
Theoretical prediction on the elastic properties of superionic material is challenging due to
the fast diffusion of cation/anion in the lattice. Here, we investigated the elastic properties of …
