Gravity and magnetic maps are a fundamental tool for mapping the tectonic fabric of the ocean floor,
allowing us to reconstruct many millions of years of Earth's plate tectonic evolution. We use the plate tectonic reconstruction software
GPlates, combined with reconstruction models developed by members of the Earthbyte group,
to reconstruct geophysical images and explore the spatio-temporal relationships between present-day seafloor morphology and plate tectonic processes.
This tutorial
contains detailed information about how to reconstruct rasters with GPlates.
