Using polarized Raman spectroscopy to study the stress gradient in mineral systems with anomalous birefringence Our PhD student Nicola Campomenosi using experimental results coupled with selected finite element models showed that the ratio...
Read moreCooling history and emplacement of a pyroxenitic lava as proxy for understanding Martian lava flows
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 moreAnother score for Mazzucchelli: Elastic geobarometry for anisotropic inclusions in cubic hosts
Another score for Mattia Mazzucchelli! In his new manuscript Mattia tackles the key issue of extending elastic barometry to anisotropic inclusions in cubic host! The change of strain in the inclusion can now be modelled using the axial equations...
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 moreQuantifying hexagonal stacking in diamond
Once again on the shock impact topic. In her new nice manuscript in Scientific Reports Mara Murri presents some of the recent considerations about structural disorder in the form of complex combinations of cubic and hexagonal stacking motifs...
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 moreViscosity experiments at superliquidus temperatures
Rheology is the key factor to understand dynamic processes and behavior of magma rising through volcanic conduit and lava emplacement on Earth or other terrestrial planets. Today we can monitor the evolution of magma and volcanic mixtures by...
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 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...
