Overview

This page bundles the available data for the Baykit Anteclise in the Siberian region. The images are hyperlinks and will open up a separate window with a high resolution PDF image of the map.
The basin data is derived from a lower resolution grid which has been upsampled using GMT. This could have introduced an accuracy which is beyond the original data resolution.

Basin name Baykit Anteclise
Region code SIB
Basin ID 4200
Plate location/code intra-cratonic/INC
Basin cross section

The basin cross section is automatically generated using the available crustal structure data sets. Sometimes the data labels are not plotted correctly, depending on the length of the section.

The location of the profile is indicated in all maps as dashed-dotted thin black line. For the endpoints of the profile, the two points of a given polygon located farthest away from each other were computed.

Dynamic topography evolution for basin centroid
Baykit Anteclise dynamic topography through time

The dynamic topography history for the basin is derived by tracking the basin centroid. The paleo-location for this point is computed using the EarthByte plate kinematic framework rotating the position back in time.

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:
