The evolution and future of earth's nitrogen cycle
TL;DR: Humans must modify their behavior or risk causing irreversible changes to life on Earth, as the damage done by humans to the nitrogen economy of the planet will persist for decades, possibly centuries, if active intervention and careful management strategies are not initiated.
Journal ArticleDOI
Zircon saturation re-revisited
TL;DR: In this paper, the authors used a Bayesian approach to optimize the calculation of the coefficients in the zircon solution model, which is given by: ln D Zr = 10108 ± 32 / T K − 1.16 ± 0.15 M − 1 − 1.48 ± 0.09 where DZr is the distribution coefficient of Zr between zirton and melt and the errors are at one sigma.

A Change in the Geodynamics of Continental Growth 3 Billion Years Ago
TL;DR: In this paper, the authors identify systematic variations in hafnium and oxygen isotopes in zircons of different ages that reveal the relative proportions of reworked crust and of new crust through time, and a marked decrease in the rate of crustal growth at ~3 billion years ago may be linked to the onset of subduction-driven plate tectonics.

Research Development on K-Ion Batteries.
Tomooki Hosaka,Kei Kubota,Kei Kubota,A. Shahul Hameed,A. Shahul Hameed,Shinichi Komaba,Shinichi Komaba +6 more
TL;DR: This review comprehensively covering the studies on electrochemical materials for KIBs, including electrode and electrolyte materials and a discussion on recent achievements and remaining/emerging issues includes insights into electrode reactions and solid-state ionics and nonaqueous solution chemistry.

The generation and evolution of the continental crust
Chris J. Hawkesworth,Chris J. Hawkesworth,Bruno Dhuime,Anna Pietranik,Peter A. Cawood,Anthony I.S. Kemp,Craig Storey,Craig Storey +7 more
TL;DR: The continental crust is the archive of the geological history of the Earth and only 7% of the crust is older than 2.5 Ga, and yet significantly more crust was generated before than subsequently.

The composition of the Earth
William F. McDonough,Shen-Su Sun +1 more
TL;DR: In this paper, the authors compared the relative abundances of the refractory elements in carbonaceous, ordinary, and enstatite chondritic meteorites and found that the most consistent composition of the Earth's core is derived from the seismic profile and its interpretation, compared with primitive meteorites, and chemical and petrological models of peridotite-basalt melting relationships.
Journal ArticleDOI
The composition of the continental crust
TL;DR: In this paper, a new calculation of the crustal composition is based on the proportions of upper crust (UC) to felsic lower crust (FLC) to mafic lower-crust (MLC) of about 1.6:0.4.
Journal ArticleDOI
The geochemical evolution of the continental crust
TL;DR: A survey of the dimensions and composition of the present continental crust is given in this paper, where it is concluded that at least 60% of the crust was emplaced by the late Archean (ca. 2.7 eons).

The chemical composition of subducting sediment and its consequences for the crust and mantle
Terry Plank,Charles H. Langmuir +1 more
TL;DR: This article evaluated subducting sediments on a global basis in order to better define their chemical systematics and to determine both regional and global average compositions, and then used these compositions to assess the importance of sediments to arc volcanism and crust-mantle recycling, and to re-evaluate the chemical composition of the continental crust.

Nature and composition of the continental crust: A lower crustal perspective
TL;DR: In this article, a three-layer crust consisting of upper, middle, and lower crust is divided into type sections associated with different tectonic provinces, in which P wave velocities increase progressively with depth and there is a large variation in average P wave velocity of the lower crust between different type sections.
