Short summary
The gneiss conductivities markedly increase with total alkali and calcium ion content. The influence of pressure on gneiss conductivity is weaker than temperature, although conductivity still increases with pressure. The results cannot be used to interpret the HC anomalies in the Dabie–Sulu UHPM belt. However, the conductivity–depth profiles for gneiss may provide an important constraint on the interpretation of field magnetotelluric conductivity results in the regional metamorphic belt.
