Lithosphere temperature gradient
WebThe geothermal gradient of 25 degrees centigrade/kilometer is thought to be restricted to the upper part of the crust. If it continued at this rate uniformly from the surface, the … 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.
