WebbThe constitution of the lunar middle mantle, which is located between two prominent discontinuities at depths of 270 and 500 km, has been investigated by a method of thermodynamic modeling. On the basis of the THERMOSEISM data base, self-consistent phase equilibrium assemblages and synthetic seismic profiles have been calculated for … WebbThermo-chemical structure of the lithospheric mantle underneath the Siberian craton inferred from long-range seismic profiles O.L.

The negative jumps of velocities through the 270 km discontinuity are δ VP / VP =−3.5% and δ VS / VS =−5.5%. There is no identical peculiarity for the low-velocity zones in the Earth’s mantle. This strong decrease of ... Webb1 okt. 2014 · Based on a self-consistent thermodynamic-geophysical approach, we convert the recent seismic models of the lunar mantle to the temperature-depth profiles using Gibbs free energy minimization and petrological constraints in the Na 2 O–TiO 2 –CaO–FeO–MgO–Al 2 O 3 –SiO 2 system.
