The following standard names are recognized by TTBOX.
Discontinuity names are not case sensitive.
Discontinuity | TTBOX name | Explanation |
---|---|---|
Conrad D. | 'conrad' | Boundary between upper and lower crust, not always present |
Mohorovicic D. | 'moho' or 'mantle' |
Boundary between crust and mantle |
Olivine-&alpha to β-Spinel phase transition, "410" | 'olivine alpha beta' or 'transition zone' |
Beginning of the mantle transition zone |
β-Spinel to &gamma-Spinel phase transition, "520" | 'olivine beta gamma' | |
Spinel-Perowskite Transition, "660" | 'olivine gamma perovskite' or 'lower mantle' |
Boundary between upper and lower mantle |
Core-mantle-Boundary, "CMB" | 'cmb' or 'outer core' or 'outer-core' |
Boundary between Mantle and Core |
Inner core Boundary, "ICB" | 'icb' or 'inner core' or 'inner-core' |
Boundary between liquid outer and solid inner core. |
Discontinuities labeled with these names in .clr or .nd files will be stored in the .conr, .moho, .d410, .d520, d660, .cmb, and .icb fields of MODEL and CLR structure variables.
Proper computation of phases which are affected by discontinuities (like PcP, PKP) is not possible if discontinuities are not named properly!
