The ICONS basin atlas is a collection of basin data for selected regions of the globe, displaying crustal structure data, computed extension factors and tectonic subsidence grids and derivatives thereof as well as the dynamic topography evolution of a given basin.
This page bundles the available data for the Siberian region region. The images are hyperlinks and will open up a separate window with a high resolution PDF image of the map. 
To view the data for individual basins, select a basin from the dropdown menu below or click the basin name in the overview table. This will open a separate page with detailed maps. 

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 paleolocation 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  

CommentsThis 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 fourdigit 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. ↑ back to the top
