Se sita a una profundidad media de unos 35 km, pudiendo encontrarse a 70 km de profundidad bajo los continentes o a tan solo 10 km bajo los ocanos. Se pone de relieve cuando las ondas ssmicas P y S aumentan bruscamente su velocidad. Constituye la superficie de separacin entre los materiales rocosos menos densos de la corteza, formada fundamentalmente por silicatos de aluminio, calcio, sodio y potasio, y los materiales rocosos ms densos del manto, constituido por silicatos de hierro y magnesio. Discontinuidad de Gutenberg B La discontinuidad de Gutenberg es la divisin entre manto y ncleo de la Tierra, situada a unos km de profundidad.

An introduction to seismological research: Immediately above the Moho, the velocities of primary seismic waves P-waves are consistent with those through basalt 6. P-wave velocities are much slower in the outer core than in the deep mantle while S-waves do not exist at all in the liquid portion of the core.
Recent evidence suggests a distinct boundary layer directly above the CMB possibly made of a novel phase of the basic perovskite mineralogy of the deep mantle named post-perovskite. Physics of the Earth and Planetary Interiors. Highest mountain, deepest lake, biggest tsunami and more.
