Fig. 9

Schematic image of geological features and heat flow distribution. The orange arrows represent the fault displacement. Where slope sediment covers thrust faults, low heat flow is found. At such sites, the sediment cover might prevent fluid flow (small blue arrows). Areas without cover sediment and with eroded surfaces have high heat flow. Around these areas, fluid flow may reach the seafloor through the active faults (large blue arrows). Near the eroded seafloor, there may be two BSRs: one that represents the pre-erosional pressure and thermal regime (black dashed line at the rightmost part), and another that has since diverged away from the seafloor in response to the post-erosional pressure and thermal regime (black line). Such surface disturbances can also contribute to high heat flow anomalies
