Radar measurements of Greenland’s ice cap thickness have revealed a sub-ice landscape that Getech has analysed in order to gain new insights into the hydrocarbon prospectivity of the marginal sedimentary basins of Greenland.
As part of this report the pre-Neogene landscape has been restored by modelling the flexural isostatic response to ice loading using different experimental values for the elastic thickness of the lithosphere(Te). Additionally, the affect of relative Paleogene hotspot motion, which are critical, have been removed. This restored landscape was then analysed to pick out the signatures of past changes in Greenland’s drainage networks.
This innovative report exposes a new paradigm for the evolution of sediment source to sink relationships in the region. Can you afford to explore the Greenland margins without the benefits of these new insights?

This Regional Report investigates…
…which of the ancient river outfalls are the mouths of major drainage systems and which are short-headed rivers.
…if incorporation of flexural rigidity concepts change the analysis compared to simple Airy isostatic correction.
…how drainage patterns have changed over time and the evidence for these changes.
…if the path of the Iceland hotspot is evident in the landscape and whether this has affected drainage patterns.
…evidence from drainage patterns of recent pre-ice tectonic events and how these events might have affected hydrocarbon prospectivity offshore.
