Electrical conductivity of carbonbearing granulite at raised temperatures and pressures

  title={Electrical conductivity of carbonbearing granulite at raised temperatures and pressures},
  author={Paul W. J. Glover and Frederick John Vine},
IT has long been recognized that the electrical conductivity of the lower continental crust is anomalously high. Both pore-saturating brines1–5 and conducting films of carbon at grain boundaries6–10 have been proposed to explain this, but the evidence remains inconclusive. Here we report measurements of electrical conductivity at high temperatures and pressures11–13 on samples of carbon-bearing and carbon-free granulites with a range of electrolyte saturations. The application of pressure to… Expand
Role of sulfur and carbon in the electrical conductivity
Electrical conductivity measurements were made on black shale samples from deep boreholes under laboratory conditions corresponding to more than 10 km burial depth. At these conditions, largeExpand
Effect of water on the electrical conductivity of lower crustal clinopyroxene
