Fossil subduction recorded by quartz from the coesite stability field In his latest paper Matteo Alvaro introduces ad method that exploits the elastic anisotropy of quartz inclusions in garnets to reconstruct the stress state at entrapment and...
Read moreLimits to the Validity of Thermal-Pressure Equations of State
In this new manuscript Ross Angel shows that for thermal-pressure Equations of State (EoS) such as the Mie-Grüneisen-Debye (MGD) the assumptions, including the quasi-harmonic approximation (QHA) and a simplified phonon density of states need to...
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 moreMulti-analytical characterization of Fe-rich magnetic inclusions in diamonds
Our physicist Marco Piazzi has now finalized a very nice article that combines several methodologies for the investigation of the magnetic response of Fe rich inclusions in diamonds. Very exciting story!! For further reading the manuscript can be...
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...

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 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 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...
