While we have applied this scheme to magma-poor rifted margin evolution, it potentially applies to other types of rifted margin or other tectonic boundaries. Under increased mantle potential temperatures, magmatism may occur earlier and to a greater extent. The SDRs and fault geometry seen in volcanic rifted margins could result from earlier magmatism changing the principal stress direction from top-down to bottom-up during the stretching phase and before widespread exhumation can begin. Future work synthesizing GeoFLAC results with geological and geophysical observations will test this hypothesis for volcanic margins such as along Scandinavia, West India, and Argentina and their conjugates. If successful, this methodology may be applied to pre-Mesozoic rift systems to investigate the effects of early-Earth thermal conditions
