Variable parameter | Meaning | Range of value |
---|---|---|
\(T_{{\text{M}}}\) | Middle mantle temperature | 1400–1750 K |
\(M^{*}\) | Reference permeability | 0–44 |
\(F_{{{\text{crst}}}}^{*}\) | The ratio of the concentration of the HPEs in the crust to that in the mantle (\({\text{HPEs}}_{{{\text{crst}}}} /{\text{HPEs}}_{{{\text{mantle}}}}\)) | 4–32 |
\(L^{*}\) | The thickness of the overturned layer after mantle overturn (see Section “Initial distribution of temperature, HPEs, and bulk composition”) | 1/5.5–1 |
