-where grain_size is set to a constant value of 5mm, Vp and Vs are the P- and S-wave seismic velocities, respectively, Vs_anomaly is the S-wave velocity anomaly relative a reference velocity profile, faults represent the composition value at plate boundaries, and cratons represent the composition value within the continental cratons. Both faults and cratons have composition values set to 0 in this ASCII file because they are defined separately using the Geodynamics WorldBuilder (GWB) {cite}`Fraters2019c` and the input file `cookbooks/equilibrium_grain_size/input_file/world_builder_smac_cratons_faults_2D.json`.

 For plate boundary geometry, we use the Nuvel model{cite}`demets:etal:1990` input as `fault` features and the locations of cratons taken from{cite}`nataf:etal:1996` input as `continental plate` features regions in GWB {cite}`Fraters2019c`. The compositional value of faults transitions smoothly from 1 at the fault trace to 0 over a width of 50 km on either side of the fault. We do this to ensure that the prescribed plate boundary viscosity which is based on the fault composition is also smooth.
-Note that while the input file includes plate boundary geometry and cratons for the whole Earth, we only compute the compositions along a cross-section in this cookbook.
