The structure of glasses and the melts from which they are formed is intrinsically disordered,
making their structural characterization difficult. Whilst the structure of solid minerals can be …

Magmas are mixtures of melt, crystals and dissolved gasses with or without crystalline
material (Mysen and Richet 2019). They play an important role in igneous processes …

Pair distribution function measurement of SiO 2 glass up to 120 GPa reveals changes in the
first-, second-, and third-neighbor distances associated with an increase in Si coordination …

With ab initio molecular dynamics simulations on a Na‐, Ca‐, Fe‐, Mg‐, and Al‐bearing
silicate melt of pyrolite composition, we examine the detailed changes in elemental …

Modelling of processes involving deep Earth liquids requires information on their structures
and compression mechanisms. However, knowledge of the local structures of silicates and …

The pressure-induced structural transformations in metasilicate MSiO 3 glass (M= Mg or Ca)
on cold-compression from ambient pressure to 17.5 GPa were investigated by neutron …

Sodium, silicon, and oxygen—the major constituents of magmatic silicate melts in the Earth's
crust and mantle—are also common ingredients in commercial flexible and scratch-proof …

Properties of liquid silicates under high-pressure and high-temperature conditions are
critical for modeling the dynamics and solidification mechanisms of the magma ocean in the …

The early Earth was marked by at least one global magma ocean. Melt buoyancy played a
major role for its evolution. Here we model the composition of the magma ocean using a six …

Under extreme conditions of high pressure and temperature, liquids can undergo substantial
structural transformations as their atoms rearrange to minimise energy within a more …
