WebLithospheric Thickness: Assume temperature in the asthenosphere at the ridge axis T a = 1300 C and the base of the lithosphere defined by T = 1100 C. In this case one can say that L = 2.016sqrt ( k t). If k = 10 -6 m 2 s -1 then L = 11sqrt (t) in kilometres and t in Ma then will have the following curve but only good to about 70 Ma.
WebFeb 11, 2024 · The crust and outermost mantle are so cold they form the solid lithosphere. But the higher temperature just below that results in a somewhat softer layer, the asthenosphere. Still deeper in the mantle it’s even hotter, but pressure is so great that the lower mantle is a hard solid.
