Two simulations of plate tectonic spreading at a mid-ocean ridge, driving mantle upwelling
and melting. Axes are labelled with depth and distance in kilometres. Colours show the
volume fraction of magma present; solid streamlines show the mantle flow; dashed contours
are lines of constant temperature (the upper surface is cold, the deep mantle is hot);
tracer particles mark the motion of the magma, where it is present. The upper panel has a
plate speed of 1 cm/year; the bottom has 5 cm/year. Mid-ocean ridges host 80% of Earth’s
volcanism. These simulation are PETSc-based numerical solutions of conservation of mass,
momentum, and energy for two phases (mantle rock; magma) and two thermochemical
components.

The movies show the effects of erosion and tectonic motion on the deflection and folding
of rock units in the upper few kilometers of the Earth. In one case we have a slower
deformation rate and a steeper initial slope whereas on the other case tectonic
deformation is an order of magnitude faster. The resulting folding patterns have some
resemblance with natural folding patterns observed in the Zagros Mountains. From the paper
