Salt crust diffusive conductance. (a) Salt crust diffusive conductance as a function of time in stage 4; ${\mathrm{\Gamma }}_{\mathit{ref}}$ is the conductance at t = 10 days; ${\mathrm{\Gamma }}_{\mathit{HC}}$ is the conductance in the Hele-Shaw cell free of crust; (b) Salt crust for t > 10 days with tentative separation between the salt finger region (crust upper region) and the salt crust lower region (region within the red dashed frame).
