Sentence examples for models of mantle from inspiring English sources

When they added the heat release from the biggest asteroids to models of mantle convection, they found that the mantle became a heating blanket rather than an ice pack.

Global backwards-in time models of mantle convection have resulted in vastly different interpretations of the transient state of dynamic topography on the U.S. Atlantic passive margin (Moucha et al., 2008; Spasojević et al., 2008; Rowley et al., 2013; Rovere et al., 2015).

Here, we test first the ability of small-scale convection to initiate subduction with the two different top boundary conditions and, second, the importance of basal heating and an initial stagnant-lid phase on the mode of plate tectonics in global models of mantle convection.

In the basic equations, we assume a simple linear dependence of the reference density (overline{rho }) on the depth 1 − z (z is the height from the bottom), overline{rho } left( z right) = 1 + left[ {1.75left( {M_{text{p}} } right)^{0.258} - 1} right]left( {1 - z} right), (7 based on the earlier models of mantle structure (Valencia et al. 2006).

(a) 1D models of mantle conductivity and (b) 1D model of mantle C-Response induction; (c) 3D conductivity model from the Time Domain approach at the Earth's surface; (d) 3D model of mantle conductivity from the Time Domain approach at a depth of 400 km showing the recovered image of a synthetic anomaly beneath the Pacific Ocean.

The most widely supported model of mantle anisotropy is olivine alignment.

Here, we present the results on subduction initiation obtained by dynamically self-consistent, time-dependent numerical modelling of mantle convection.

In contrast, according to the model of mantle heating by impact of Monteux et al. (2015), in the vicinity of the impact, the lower mantle is heated to the core temperature and the CMB heat flux becomes zero, whereas away from it the lower mantle temperature is unchanged.

Based on the model of mantle convection and data from Hadean zircons, it is probable that the mantle was in a stagnant-lid convection mode at the time of formation of the EER i.e., within 30 Myr of Solar System formation.

Modelling of mantle convection becomes more realistic when the top surface of the mantle is treated as a free surface instead of being vertically fixed (i.e. free slip): A free surface allows for natural plate bending (Crameri et al. 2012b).

Most recently, Kuvshinov and Olsen (2006) derived a global model of mantle conductivity from five years of CHAMP, Ørsted and SAC-C magnetic data and demonstrated the necessity of taking into account the contributions of a laterally heterogeneous surface shell representing the distribution of oceans and continents.
