Modelled depth and thermal history for sediments offshore Sumatra (NERC grant NE/P012140/1)

The thermal state of marine sediments controls a range of potential dehydration reactions as sediments are subducted. In thick sediment sections it is possible that reactions that would normally occur within a subduction zone start offshore of the deformation front. This scenario may be occurring at the Sumatra subduction zone (e.g. Geersen et al., 2013; Huepers et al., 2017). We have investigated this possibility by modelling the thermal and depth history of sediments offshore Sumatra. We have used a range of different assumptions about how the sediments decompact with depth, as well as testing the dependence on the seismic velocities used for depth conversion of the horizons.

Data Quality

The data are generated using SlugSed modelling software (Hutnak and Fisher, 2007) using a range of different scenarios to account for variations due to parameters that are poorly constrained.
