Table 1 Estimates of thermal effects of processes not modeled in Syracuse et al. (2010)
Effect | Impact | Temperature difference |
|---|---|---|
Primary | ||
Melt migration | Local | Few 100\(^\circ\)C |
Backarc spreading | Local and shallow | Few 100\(^\circ\)C |
Time-dependence of forcing parameters | Global | 100–200\(^\circ\)C |
3D flow effects | Global | 100–200\(^\circ\)C |
Rheology of the mantle wedge | Global | ?? |
Variable radiogenic heating | Local | \(\sim\)50–100\(^\circ\)C |
Decoupling-coupling transition | Local | Could be large locally |
Secondary | ||
Fluid flow in slab | Local to shallow slab | 10–50\(^\circ\)C |
Shear heating | Local to seismogenic zone | 50–100\(^\circ\)C |
Phase changes | Local to shallow slab | 50\(^\circ\)C |
