We study a new class of high‐resolution mantle circulation models and predict their
corresponding elastic heterogeneity. Absolute temperatures are converted to seismic …

Heat transfer across the core mantle boundary (CMB) is fundamentally important to Earth's
internal energy budget. But the amount of heat entering the mantle from the core is poorly …

Seismic observations indicate that Earth's lower mantle is homogeneous as revealed by
smooth depth variations of the bulk sound velocity and Bullen's inhomogeneity parameter η …

A new post-perovskite phase has been identified recently from both X-ray observations and
first-principles calculations. This novel phase change occurs at a depth about 200 km above …

The new post-perovskite phase near the core–mantle boundary has important ramifications
on lower mantle dynamics. We have investigated the dynamical impact arising from the …

It is well established that the temperature gradients in the interiors of internally heated
mantle convection models are subadiabatic. The subadiabatic gradients have been …

Tomographical results are commonly presented in the form of color images and not much
statistical quantification has been carried out on the derived models. Correlation between …

The temperature gradient in the lower mantle is fundamental in prescribing many transport
properties, such as the viscosity, thermal conductivity and electrical conductivity. The …

Valuable information concerning the style of mantle density stratification can be gleaned
from the spatial distribution of Bullen's parameter. By means of numerical modelling of 2-D …

The issue concerning the state of adiabaticity of mantle plumes has been examined in a
cartesian two-dimensional box with an aspect-ratio of six. We have investigated in the quasi …
