摘要：The electrical conductivity of brine-bearing quartzite with fluid fractions of 0.19 to 0.30 and salinity of 3 to 17 wt.% was measured at 800 to 1,100 K and 1 GPa.The conductivity of the brine-bearing quartzite increases with salinity and fluid fraction, but is almost independent of temperature.Our results suggest that regions of high conductivity (10−3 to 10−2 S/m) in the crust could be explained by the presence of quartzite with fluids of salinity similar to that of seawater.To account for those regions with the highest conductivity of 10−110 wt.%) is required.
