The temperature anomalies in the Earth's mantle associated with thermal convection can be inferred from seismic tomography, provided that the elastic properties of mantle minerals are known as a function of temperature at mantle pressures. At present, however, such information is difficult to obtain ...
The Earth is made up of three layers. The core is the dense innermost layer of the earth, divided into two parts. The crust is the Earth's thin outer, rocky layer. The mantle is the largest layer of the Earth and is located between the core and the crust. The majority of the mantl...
Examining kimberlites, an igneous rock that formed from a magma generated in the upper mantle and then moved through the uppermost mantle toward the Earth's surface, from Kansas near MCR shows a fertile lherzolite composition. This composition could reflect melt-metasomatism beneath this region (...
Subduction (or sagduction) of the uppermost crust in an ultrahot orogen setting brought shales and greenstones to the lower crust. Ultrahigh temperature (UHT) conditions are the result of high mantle potential temperatures and self- heating by the radioactive inventory of the subducted lithologies...
The δ18O-δD relation shows that the main source is the meteoric water, together with some sedimentary water, but there are no deep magmatic water and mantle water which recharge the geothermal water in the basin. Through examining the distribution pattern of hydrogen-oxygen isotopic signatures,...

[1] We jointly invert global seismic traveltime data, mean mass, and mean moment of inertia for Earth's mantle composition and thermal state using a stochastic sampling algorithm. The chemical composition of the silicate Earth is modeled within the system CaO-FeO-MgO-Al2O3-SiO2. Given ...
