Further discussion of the Lehmann discontinuity is found in Karato.

This boundary is known as the Bullen discontinuity, or sometimes as the Lehmann discontinuity.

During this work, she discovered another seismic discontinuity, which lies at depths between 190 and 250 km and is usually referred to as "Lehmann discontinuity" in honor of its discoverer.

The Lehmann discontinuity refers to an abrupt increase of P-wave and S-wave velocities in the vicinity of 220 30 km depth, discovered by seismologist Inge Lehmann.

This lower boundary, found beneath the continental lithosphere and oceanic lithosphere away from mid-ocean ridges, is sometimes referred to as the Lehmann discontinuity and occurs at about 220 30 km depth.

They can still appear in the solid inner core: when a P-wave strikes the boundary of molten and solid cores, called the Lehmann discontinuity, S-waves will then propagate in the solid medium.

Francis Birch noted that the "Lehmann discontinuity was discovered through exacting scrutiny of seismic records by a master of a black art for which no amount of computerization is likely to be a complete substitute..."
