2011, Earth-Science ReviewsCitation Excerpt :Such a study can also test whether the geologically suggested episodic emergence of supercontinents is realized in the numerical model. The thermal effect of accumulation of continental crust with compositionally buoyant materials on mantle convection has been previously evaluated in a series of papers (Lenardic and Kaula, 1994, 1995, 1996; Lenardic, 1997; Moresi and Lenardic, 1997; Lenardic, 1998; Moresi and Lenardic, 1999). Convective overturn of the mantle causes chemically light crust to thicken above the mantle downwelling and surface heat flux above the thick crust is lower than that above the mantle (Lenardic and Kaula, 1995).
Preliminary three-dimensional model of mantle convection with deformable, mobile continental lithosphere
2010, Earth and Planetary Science LettersCitation Excerpt :The mechanism of crustal production and growth should be incorporated in a future numerical model so as to confirm this geologically suggested episodic emergence of supercontinents. The thermal effect of accumulations of continental crust with compositionally buoyant materials on mantle convection is previously published in a series of papers (Lenardic, 1997; Lenardic, 1998; Lenardic and Kaula, 1995; Lenardic and Kaula, 1996; Moresi and Lenardic, 1999; Moresi and Lenardic, 1997). Walzer and Hendel (2008) have recently performed simulations of 3D spherical mantle convection with the growth of a continent by considering the chemical differentiation and redistribution of incompatible elements.
The combined effects of continents and the 660 km-depth endothermic phase boundary on the thermal regime in the mantle
2009, Physics of the Earth and Planetary InteriorsCitation Excerpt :Being less dense and therefore, more buoyant than the mantle, continents do not participate in mantle overturn. Both numerical- and laboratory-based models have been created to investigate the dynamic interaction between the continental lithosphere and the mantle (Gurnis, 1988; Zhong and Gurnis, 1993; Guillou and Jaupart, 1995; Lowman and Jarvis, 1995, 1996; Lenardic and Kaula, 1995, 1996; Lenardic, 1997, 1998; Lenardic et al., 2005; Moresi and Lenardic, 1997; Grigné and Labrosse, 2001; Grigné et al., 2005, 2007a,b). Lenardic and Moresi (2001, 2003) investigated the variation of the surface heat flow as a function of the thickness and the lateral extent of the thermally coupled continents, and derived a parameterized model based on their numerical model results.

2004, Trends in Ecology and EvolutionIntraplate tectonics: Feedback between radioactive thermal weakening and crustal deformation driven by mantle lithosphere instabilities
2004, Earth and Planetary Science LettersCitation Excerpt :The results similarly show that time-varying over-compensated topography can develop under the influence of sub-lithospheric loading, but the analyses impose a constant mantle buoyancy load and consequently neglect the influence of time-dependent convection in the underlying mantle. Three-dimensional isoviscous simulations of time-dependent mantle convection that include a buoyant overlying crust demonstrate variable crustal accumulation and thickening above regions of downwelling mantle flow [17,18]. The resulting high positive topography is not in (Airy) isostatic equilibrium, as the crustal thickening is dynamically supported by the time-varying mantle fluid flow.
