  Name Sediment thickness (km) Continental plate velocity (cm yr−1) Mantle wind (cm yr−1) Initial serpentinization
M1 Steep 4 1 0 Yes
M2 Flat 4 3 5 Yes
M3 Flat (no initial serpentinization) 4 3 5 No
M4 Flat (static continental plate) 4 from 3 to 0 *1 5 Yes
M5 Steep (500 m sediment thick) 0.5 1 0 Yes
M6 Flat (500 m sediment thick) 0.5 3 5 Yes
