Figure 1From: Electrical conductivity of brine-bearing quartzite at 1 GPa: implications for fluid content and salinity of the crustRepresentative SEIs of recovered samples. (a) Run A2354 with fluid fraction of 0.19 and salinity of 3 wt.%. (b) Run A2343 with fluid fraction of 0.29 and salinity of 5 wt.%. The dark-gray and light-gray regions correspond to the fluid portions (filled with epoxy) and quartz, respectively.Back to article page
