A quiet quantum revolution in Earth's deep interior
Renata Wentzcovitch, Laura Cobden, Christine Houser +2
The Earth's lower mantle hosts a subtle but pervasive quantum phenomenon: the pressure-induced spin crossover of iron in its dominant minerals, bridgmanite and ferropericlase. In t…
The origin of Earth's mantle nitrogen: primordial or early biogeochemical cycling?
H. Kurokawa, M. Laneuville, Y. Li +5
Earth's mantle nitrogen (N) content is comparable to that found in its N-rich atmosphere. Mantle N has been proposed to be primordial or sourced by later subduction, yet its origin…
Subduction and atmospheric escape of Earth's seawater constrained by hydrogen isotopes
Hiroyuki Kurokawa, Julien Foriel, Matthieu Laneuville +2
The hydrogen isotopic (D/H) ratio reflects the global cycling and evolution of water on Earth as it fractionates through planetary processes. We model the water cycle taking seaflo…
Persistence of Strong Silica-Enriched Domains in the Earth's Lower Mantle
Maxim D. Ballmer, Christine Houser, John W. Hernlund +2
The composition of the lower mantle comprising 56% of Earth's volume remains poorly constrained. Among the major elements, Mg/Si ratios ranging from 0.91.1, such a…
The language of exoplanet ranking metrics needs to change
Elizabeth Tasker, Joshua Tan, Kevin Heng +14
We have found many Earth-sized worlds but we have no way of determining if their surfaces are Earth-like. This makes it impossible to quantitatively compare habitability, and prete…
Influence of the iron spin crossover in ferropericlase on the lower mantle geotherm
Juan J. Valencia-Cardona, Gaurav Shukla, Zhongqing Wu +3
The iron spin crossover in ferropericlase introduces anomalies in its thermodynamics and thermoelastic properties. Here we investigate how these anomalies can affect the lower mant…
