The reactivity of xenon with terrestrial oxides was investigated by in situ synchrotron x-ray diffraction. At high temperature (T > 500 kelvin), some silicon was reduced, and the pressure stability of quartz was expanded, attesting to the substitution of some xenon for silicon. When the quartz was quenched, xenon diffused out and only a few weight percent remained trapped in samples. These results show that xenon can be covalently bonded to oxygen in quartz in the lower continental crust… Expand
Xenon and Argon: A contrasting behavior in olivine at depth
Abstract Xenon in the atmospheres of the Earth and Mars is characterized by a low abundance compared to other noble gases and by a depletion in light isotopes. By means of combined chemical analysis,Expand
Bonding of xenon to oxygen in magmas at depth
Abstract The field of noble gases chemistry has witnessed amazing advances in the last decade with over 100 compounds reported including Xe oxides and Xe–Fe alloys stable at the pressure-temperatureExpand
The Xe-SiO 2 System at Moderate Pressure and High Temperature
Xenon (Xe), the heaviest of the stable noble gases, is missing by a factor of 20 relatively to other noble gases, when comparing the Earth's and Mars's atmospheres with chondrites. In this work, theExpand
Stability of xenon oxides at high pressures.
Using an ab initio evolutionary algorithm, the existence of thermodynamically stable Xe-O compounds at high pressures is predicted and calculations indicate large charge transfer in these oxides, suggesting that large electronegativity difference and high pressure are the key factors favouring the formation of xenon compounds.

Synthesis of Xenon and Iron-Nickel Intermetallic Compounds at Earth's Core Thermodynamic Conditions.
The results indicate the changing chemical properties of elements under extreme conditions by documenting that electropositive at ambient pressure elements could gain electrons and form anions. Expand
Reaction between nickel or iron and xenon under high pressure
ABSTRACT Xe–Ni and Xe–Fe systems are studied in a pressure range relevant to the Earth's core (135–210 GPa) using laser-heated diamond anvil cells and synchrotron X-ray diffraction. The stability ofExpand
High-pressure stabilization of argon fluorides.
HSE06 calculations indicate that above 60 GPa ArF2-containing molecular crystals can be obtained by a reaction between argon and molecular fluorine, which enables synthesis of argon fluorides in bulk and at room temperature. Expand
Behavior of Xenon-Iron System under the Core Pressure
The so-called “Missing Xe” problem is a long standing unsolved problem and is related to many fields in Earth science: formation process and evolution of the Earth, origin and evolution of theExpand
Formation of xenon-nitrogen compounds at high pressure
Through a series of optical spectroscopy and x-ray diffraction experiments, this work demonstrates the formation of a novel van der Waals compound formed from binary Xe-N2 mixtures at pressures as low as 5 GPa. Expand

The chemistry of noble gases was for a long time dominated by fluoride-bearing compounds of xenon, but the last two decades have brought new insights, including insights involving a novel type of non-covalent interaction (aerogen bonding), discoveries of new xenon oxides, oxide perovskite frameworks and evidence for an abrupt increase of Xenon reactivity under extreme pressure-temperature conditions.

Plutonium-fission xenon found in Earth's mantle
Data from mid-ocean ridge basalt glasses indicate that the short-lived radionuclide plutonium-244 that was present during an early stage of the development of the solar system is responsible forExpand
Structure, Bonding, and Geochemistry of Xenon at High Pressures
Although xenon becomes metallic at pressures above about 100 gigapascals, a combination of quantum mechanical calculations and high pressure–temperature experiments reveals no tendency on the part ofExpand
Trapping of xenon in ice - Implications for the origin of the earth's noble gases
Although the Earth's atmosphere contains Ne, Ar, and Kr in about C1,2-chondrite proportions, Xe is depleted about 20-fold. To test the suggestion that the “missing” Xe is trapped in Antarctic ice, weExpand
Abundances and Isotopic Compositions of Rare Gases in Granites and Thucholites
