Melt-solid Segregation and Fractional Magma Ocean Solidification with Implications for the Evolution Of
Introduction: Large planetary bodies are likely to have been significantly melted during their accretion, simply as a consequence of the potential energy of accretion if accretion occurs rapidly enough or possibly due to giant impacts [1]. Since the solidus and liquidus temperatures of mantle mineral assemblages increase with pressure more rapidly than temperature along an adiabat, solidificati...
متن کاملOn the Scale of Lunar Mantle Overturn following Magma Ocean Fractional Solidification: the Role for Multiple Scales of Convective Motion,
Introduction: In understanding the evolution of the Moon, a number of its fundamental magmatic characteristics must be explained in the context of other geophysical and geological observations. Volcanic activity subsequent to the formation of anorthositic crust was dominated by the eruption of mare basalt. (1) The main phase of mare volcanism began ~500 Myr after the crystallization of the anor...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
MIXING IN NUMERICAL MODElS OF MANTLE CONVECTION INCORPORATING PLATE KINEMATICS
The process by which subducted lithosphere is mixed by mantle convection is investigated in numerical calculations. The results show that the observed isotopic heterogeneity of mantle sources and their ancient (1-2 b.y.) apparent ages are consistent with convective mixing. Passive tracers, which are introduced below "trenches," are efficiently dispersed, but nonetheless, heterogeneities in trac...
متن کاملTerrestrial Magma Ocean Solidification and Formation of a Candidate D ′ ′ Layer
In this thesis we investigate the solidification of early magma oceans on the Earth and the formation of a deep dense layer at the core-mantle boundary. We also study the concentrations and densities of the last layers of the solidified magma ocean and how they create a deep dense layer after solid-state overturn. The deep dense layer that forms in our model matches the bulk physical properties...
