Multivariable Dependence of Fe-Mg Partitioning in the Lower Mantle High-pressure diamond-cell experiments indicate that the iron-magnesium partitioning between (Fe,Mg)SiO$_3$-perovskite and magnesiowustite in Earth's lower mantle depends on the pressure, temperature, bulk iron/magnesium ratio, and ...

Stability of phlogopite at high pressures and possible presence of phlogopite in the earth's upper mantle High-pressure experiments have been made on the stability of natural and synthetic phlogopites by the tetrahedral-anvil type high-pressure apparatus in the pressure range from 41 to 96 kb (ki...
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,...

Here, we study three fundamental climatic phenomena: The seasonal lag, the diurnal lag, and the asymmetry of daily temperature variation. We write a nonlinear ODE based on an energy balance for surface temperature and humidity. The model focuses on small regions of the Earth’s surface; it rep...
