Lucia Perez presented COMPASS-related research at the SAMPLE colloquium, Heidelberg, Germany

Posted on 14/06/2013

The SAMPLE colloquium gathers professionals from the field of geology and with a common research interest: the tectonic evolution of the South Atlantic Ocean. This year’s edition took place between June 11th and June 14th in Heidelberg. Some of the topics discussed were the influence of mantle plumes on the dynamics of rifting, the advances on lithosphere modelling and the influence of passive margin evolution on hydrocarbon generation and leakage.

Presentation title: Seafloor depth through time in the South Atlantic”

Abstract: Accurate and reliable tectonic models describing plate motions from Early Cretaceous to present are key for this project’s main aim: to develop palaeo-bathymetric models of the Ocean’s conjugate margins, depicting the topography of the ocean floor. Knowledge of past plate motions provides the keys for modelling paleobathymetry by allowing us to construct a high resolution age grid that will in turn be the base for modelling thermal subsidence. However, many other factors affect bathymetry at smaller temporal and spatial scales, both within the ocean and at its margins. Assessing and quantifying these processes is key to increase the resolution and accuracy of paleobathymetric maps. Understanding ocean topography is essential if its role in paleoclimate change is to be properly understood. Also, it will shed light on the tectonic and stratigraphic processes that shape basin evolution on rifted margins”
