A crystallizing dense magma ocean at the base of the Earth’s mantle
TL;DR: It is shown that a stable layer of dense melt formed at the base of the mantle early in the Earth’s history would have undergone slow fractional crystallization, and would be an ideal candidate for an unsampled geochemical reservoir hosting a variety of incompatible species for an initial basal magma ocean thickness of about 1,000 km.
Journal ArticleDOI
Global warming of the mantle at the origin of flood basalts over supercontinents
TL;DR: The authors showed that continental aggregation promotes large-scale melting without requiring the involvement of plumes, when only internal heat sources in the mantle are considered, and that the formation of a supercontinent causes the enlargement of flow wavelength and a subcontinental increase in temperature as large as 100 °C.
Journal ArticleDOI
A case for late-Archaean continental emergence from thermal evolution models and hypsometry
TL;DR: Rey et al. as discussed by the authors investigated the continental freeboard predicted using different models for the cooling of the Earth and showed that constancy of the freeboard is possible throughout the history of the planet as long as the potential temperature of the upper mantle was never more than 110−210°C hotter than present.
Journal ArticleDOI
Global warming of the mantle beneath continents back to the Archaean
TL;DR: Coltice et al. as discussed by the authors used 3D numerical simulations of mantle convection to show that the mantle global warming model could explain the peculiarities of magmatic provinces that developed during the formation of Pangea and Rodinia, as well as putative Archaean supercontinents such as Kenorland and Zimvaalbara.
Journal ArticleDOI
Geochemical observations and one layer mantle convection
Nicolas Coltice,Yanick Ricard +1 more
TL;DR: In this article, a time dependent model with five reservoirs (bulk mantle, continental crust, atmosphere, residual deep mantle and DQ) is studied for Rb/ Sr and U/Pb/He systems.
