Abstract
We present palaeo-heat flow assessment for a stratigraphic section located on a deep-water passive margin. For the palaeo-heat flow assessment we apply the thermo-tectonic modelling software TECMOD2D, which consists of a numerical forward model for sedimentary basin formation and an automatic inversion algorithm. The forward model is coupled with an inversion algorithm that iteratively finds the optimal set of thinning factors and palaeo-water depths, which fit any observed basin stratigraphy best. This optimal set of thinning factors and palaeo-water depths finally provides the thermo-tectonic history including the palaeo-heat flow of the investigated section. We apply two finite rifting events between 138 and 116 Ma and 116 and 110 Ma. The palaeo-heat flow assessment yield a maximal heat flow at the crust-sediment boundary of around 3.1 HFU at around 110 Ma. The area of maximal heat flow is around 80 km wide. The average calculated present day heat flow is around 1.3 HFU. The temperature computed using the results of TECMOD simulation are compared with well measurements.
