Nitrogen is ubiquitous in both natural and laboratory-grown diamond, but the number and
nature of the nitrogen-containing defects can have a profound effect on the diamond …

Earth's carbon, derived from planetesimals in the 1 AU region during accretion of the Solar
System, still retains similarities to carbon found in meteorites (Marty et al. 2013) even after …

Geothermobarometric calculations for a worldwide database of inclusions in diamond
indicate that formation of the dominant harzburgitic diamond association occurred …

This chapter is devoted to the carbon and nitrogen stable isotope compositions of terrestrial
diamonds with a strong focus on monocrystalline diamonds formed in Earth's mantle. The …

We comprehensively compile and review N content in geologic materials to calculate a new
N budget for Earth. Using analyses of rocks and minerals in conjunction with N–Ar …

Minerals included in diamonds provide direct information about the petrologic and chemical
environment of diamond crystallization. They record information relating to local and …

The nature and cause of deep earthquakes remain enduring unknowns in the field of
seismology. We present new models of thermal structures of subducted slabs traced to …

Primarily on the basis of C, N, S, and O stable isotope systematics, this article reviews recent
achievements in understanding diamond formation and growth in Earth's mantle. Diamond …

Plate tectonics plays a vital role in the evolution of our planet. Geochemical analysis of
Earth's oldest continental crust suggests that subduction may have begun episodically about …

Nitrogen solubility in the upper mantle minerals forsterite, diopside, enstatite and pyrope has
been quantified by SIMS measurements of nitrogen-saturated, synthetic samples. The …
