Nettet1. jan. 2012 · The thickness of the lithosphere can vary geographically by hundreds of kilometres (see fig. 1 from Conrad & Lithgow-Bertelloni 2006 ). In oceanic regions, crustal thickness is nearly constant, but lithospheric thickness depends on the age of the ocean floor and ranges from 0 at the ridge to as much as 100 km for the oldest ocean floor. Nettetinside the lithosphere, and a negative anomaly due to high temperature outside, they may appear as one anomaly due to smearing, hence it may not be possible to determine lithosphere thickness properly.
