In this work, we report an experimental observation of a new CaCO3 calcite-Vb phase,
which occurs as the intermediate between aragonite and calcite-V at pressures> 3.5 GPa …

In addition to ultramafic and mafic associations, a primary natrocarbonatitic association
occurs in the lower mantle. To date, it was identified as inclusions in diamonds from the …

We report the crystal structure of dolomite-IV, a high-pressure polymorph of Fe-dolomite
stabilized at 115 GPa and 2500 K. It is orthorhombic, space group Pnma, a= 10.091 (3), b …

Using molecular dynamics simulation and evolutionary metadynamic calculations, a series
of structures were revealed that possessed enthalpies and Gibbs energies lower than those …

In the present article, we disclose shock wave induced crystallographic switchable phase
transition of calcium carbonate nano particles (CaCO 3 NPs). The observed profiles of …

This article is dedicated to the occurrence, relevance, and structure of minerals whose
formation involves high pressure. This includes minerals that occur in the interior of the Earth …

The stability of the high-pressure CaCO 3 calcite (cc)-related polymorphs was studied in
experiments that were performed in conventional diamond anvil cells (DAC) at room …

A synthetic CaCO 3–SrCO 3 solid solution with composition Ca 0.82 Sr 0.18 CO 3 was
investigated by single-crystal X-ray diffraction in the pressure range between 0 and 22 GPa …

Phases of CaCO3 stabilized at high pressures and temperatures are the potential agents of
the global carbon cycle, transferring oxidized carbon in deep Earth's interiors and thus are of …

Calcite and vaterite crystallisation is strongly influenced by the presence of additives during
the reaction process, as demonstrated by organic molecules in biogenic calcium carbonate …
