Dynamic topography for basin centroids

The dynamic topography history for the different basins is derived by tracking the basin centroid for any given basin in a region. The paleo-location for the basin centroid is computed using the EarthByte plate kinematic framework.

The dynamic topography model is derived from the S20RTS seismic tomography model (Ritsema et al., 99) by converting seismic velocites to density anomalies using an empirical scaling factor of 0.25. The density anomalies are then advected back in time to compute mantle flow with plate motions superimposed (using the EarthByte plate rotation framework) as surface boundary conditions. The dynamic topography is then derived from the computed density distribution using a free upper boundary. For details regarding the methodology see the following papers:

Dynamic topography vs. anomalous tectonic subsidence
There is no grid with 2m resolution for this region available

Comments

This plot show the amount of total dynamic topography for the last 70 Ma plotted versus the computed anomalous tectonic subsidence for any given basin in this region. The basins are identified by their basin ID (a four-digit number), this number is used as unique identifier throughout this study.

The dynamic topography model is the same as used in the dynamic topography evolution of the basin. For the computation of anomalous tectonic subsidence, please refer to Thesis Chapter 4 and compare the anomalous tectonic subsidence maps for the individual basins and the region.
