Cooling history and emplacement of a pyroxenitic lava as proxy for understanding Martian lava flows Our PhD student Mara Murri at her second Scientific Reports paper for this year! Congratulations!! She has now concluded her studies on the...
Read moreOne more milestone: “Assessment of the reliability of elastic geobarometry with quartz inclusions”
It took overall about three years but we think we now start understanding things. This is science, only 3 years to start understanding. Thank you Mattia Bonazzi for this wonderful opportunity and the brilliant work. Check out Mattia...
Read moreQuartz‐in‐garnet and Ti‐in‐quartz thermobarometry for gneiss from eastern Papua New Guinea
With this new manuscript just published in Journal of Metamorphic Geology Joe has done an excellent job in showing us advantages and limitations of elastic barometry (quartz in garnet) combined with chemical thermometry (Titanium in quartz) to...
Read moreThe pressure‑induced phase transition(s) of ZrSiO4: revised
A new brilliant manuscript by Boriana and Naemi that finally revise the phase transition(s) of ZrSiO4 at high pressure conditions. In this manuscript published in Physics and Chemistry of Minerals they present the experimental proof for the...
Read moreEditors Selections: Notable papers on American Mineralogist (June 2019)
Quoting the really nice paragraph by the Editors of American Mineralogist about our paper: “stangaronite….”! Stangarone et al. (page 830) used density functional theory (DFT) simulations of the structures of zircon and reidite...
Read moreNeed an equation of state for a stiff anisotropic mineral?
In his latest manuscript Gabriele show us how to determine the thermo-elastic behaviour of rutile combining X-ray diffraction data at highP and high T together with direct elastic measurements. The manuscript then presents a series of...
Read moreEquations of State of stiff anisotropic minerals: The example of rutile
Gabriele Zaffiro, in his new manuscript presents an assessment of the thermo-elastic behaviour of rutile based on X-ray diffraction data and direct elastic measurements available in literature. Gabriele’s results confirm that the...
Read moreElastic geobarometry using zircons
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...
Read moreMagnesiochromite inclusions in diamonds: what do they tell us?
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...
Read moreJoin the PetroChro-19 workshop: Melting, modelling, dating the crust
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...
