In her latest study Claudia Stangarone carried out ab initio hybrid Hartree-Fock/Density Functional Theory simulations to determine the structure and vibrational modes of zircon, ZrSiO4, as a function of different applied strains. In her...

In this new nice chapter of the saga of the orientation of inclusions in diamonds Paolo Nimis proposes the mechanical interaction between euhedral crystals in a fluid-rich environment as the most likely mechanism to produce the observed...

Shock in meteorite impacts may transform zircon (ZrSiO4) into a denser polymorph, reidite, but the mechanism and significance of this transformation has been obscured by discrepancies between observations on natural and experimental samples. In...

Mara Murri marks the beginning of the new year with an incredibly nice paper showing the effect of non-hydrostatic stresses on the structure of alpha-quartz. This investigation carried out through ab initio hybrid Hartree–Fock/DFT simulations...

In his new paper Nicola Campomenosi addresses the issues related to the release of the residual pressure in the inclusion due to exposure to the external pressure after polishing of the thin section. He illustrates with a careful set of...

In her new paper published on American Mineralogist, Mara Murri, describes a method for determining the strains in quartz inclusions from Raman spectroscopy using the concept of the phonon-mode Grüneisen tensor, which we determine by ab initio...

Continuous phase transitions in minerals, such as the α–β transition in quartz, can give rise to very large non-linear variations in their volume and density with temperature and pressure. In Angel et al 2017 we present a simplified description...
