The Panalesis model and its derivative maps: Implications for global long-term interaction between geodynamics and surface processes

The Panalesis model consists of global maps created every 10 million years or so from the Neoproterozoic to the present. These maps rely on a maximum of data from multiple sources (paleomagnetism, fossils, lithofacies, geochemistry, etc.) and comply with the rules of plate tectonics, following our Dual Control Approach methodology.

Once the global plate tectonics model has been defined, it is possible to derive many other types of maps. The first type of maps to be derived are palæogeographic maps. We supplement them however by maps of the age of the sea-floor, maps of accretion / subduction rates, maps of volume of subducted lithosphere, maps of hydrothermal alteration at mid-oceanic ridges, maps of crustal and lithospheric thickness, etc., which constitute the Panalesis Atlas. Associated with climate models, we show here an example of maps depicting the evolution of the drainage system at global scale through time and estimates of sediment fluxes over the Phanerozoic.
