Conducivity ranges for the materials making up the earth crust and lithospheric mantle, modified from (Jones 1999). Bold black lines indicate the following specific conductivity values, chosen to construct the model (in S/m): A—10-2 (upper crust, offshore with young crust); B—10-3 (upper crust, offshore with sea depth more 500 m); C— 2×10-4 (upper crust, offshore shelf and onshore), D—10-2 (lower crust, offshore with young crust); E— 5×10-3 (lower crust, other regions); F—10-3 (oceanic lithosphere, 50–100 km depth); G— 5×10-4 (oceanic lithosphere, 30–50 km depth); H—10-4 (oceanic lithosphere, 15–30 km depth), I— 3×10-5 (oceanic lithosphere, 0–15 km depth); J—10-2 (continental lithosphere)
