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...
Read moreNew insights into the zircon-reidite phase transition
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...

This short course, organized by Silvio Ferrero and Pierre Lanari aims to offer to PhD students and early carrier scientists working in the fields of metamorphic petrology, petrochronology and geochemistry a detailed overview of the most recent...
Read moreStructure and properties of quartz under non-hydrostatic stress
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...

Come and see us at SIMP in Catania. The Conference of the “Società Italiana di Mineralogia e Petrologia” SIMP where we will present some of the new exciting results on elastic barometry and metorite impact processes. Here below you...
Read moreStrain release after polishing
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...
