Lithosphere properties
WebMechanical lithosphere - that portion of the earth which has sufficient strength so that it acts a a brittle or rigid solid - cannot convect. As such, because temperature will control the mechanical properties of the rocks the thickness of the lithosphere is dependent on the heat flow and geothermal gradient. Web1 jan. 2012 · With the strategy outlined above, de Koker et al. made two important innovations to determine the density of the mantle lithosphere: (1) Compute the density of depleted and undepleted mantle layers as a function of depth using a self-consistent thermodynamic model for mantle petrology and physical properties (Stixrude & Lithgow …
