core/ A9135E Earth core and lower mantleIn this paper we elaborate on suggestions in the recent literature that the mantle convects uniformly through its entire depth. The main novel feature introduced here, which leads to a satisfactory account of earth temperatures, it the assumption of a ...
Transformation Kinetics in the Earth's Interior Transformations of mantle minerals have a great effect on the dynamics of the descending oceanic plate through metastable reactions and changes in the micr... Tomoaki,KUBO - 《Review of High Pressure Science & Technology》 被引量: 6发表: 1999年 Arq...
Carbon in the upper mantle controls incipient melting of carbonated peridotite and so acts as a critical driver of plate tectonics. The carbon-rich melts that form control the rate of volatile outflux from the Earth’s interior, contributing to climate evolution over geological times. However, att...
Finite element numerical modeling has been carried out in order to investigate the effect of the depth- and temperature-dependent viscosity on the thermal convection occurring in the Earth's mantle. Calculations were made in a 2D spherical shell domain applying Boussinesq approximation. It was establi...

Surface heat flow has been observed to be highly variable in the Nankai subduction margin. This study presents an investigation of local anomalies in surface heat flows on the undulating seafloor in the Nankai subduction margin. We estimate the heat flow

It has been proposed that Earth's interior has a fundamental discontinuity at mid-mantle depths of ∼400-1000 km, marking the mantle transition zone (MTZ) between mantle layers below and above (e.g., Bullen, 1940, 1947). The lower boundary of the MTZ was later reclassified as the 660...
Convective circulation of the mantle causes deflections of the Earth's surface that vary as a function of space and time. Accurate measurements of this dynamic topography are complicated by the need to isolate and remove other sources of elevation, arising from flexure and lithospheric isostasy. The...
(S-wave) splits into two orthogonal components with different velocities when passing through an anisotropic medium, provides some of the most direct constraints on anisotropy in the Earth and has been widely used to investigate seismic anisotropy in the crust and upper mantle of tectonically active...
