Table 2 σ f with different salinities derived from HS+, cube models, and Archie’s law

From: Electrical conductivity of brine-bearing quartzite at 1 GPa: implications for fluid content and salinity of the crust

Geometrical model Salinity of 3 wt.% Salinity of 5 wt.% Salinity of 10 wt.% Salinity of 17 wt.%
HS+ model 0.8 (0.2) 1.4 (0.1) 3.8 (0.6) 20 (3)
Cube model 0.8 (0.2) 1.4 (0.2) 4.0 (0.7) 21 (3)
Archie’s lawa 0.5 (0.1) 1.0 (0.1) 2.7 (0.4) 15 (2)
  1. Numbers in parentheses represent the uncertainties calculated based on propagation of uncertainties of the fluid fraction and the conductivities (σb, σs). σf, conductivity of fluid. aThe m value of Archie’s law was assumed to be 1.
