Crossing isomekes: elastic geothermobarometry of quartz and zircon in garnet from UHP rocks Characterizing the pressure and temperature (PT) histories of eclogite-facies rocks is of key importance for unravelling subduction-zone processes at all...
Read moreElastic geobarometry beyond cubic hosts
Elastic geobarometry beyond cubic hosts In this publication, Joseph Gonzalez, Mattia Mazzucchelli developed and tested a new model for elastic thermobarometry that will allow for the use of non-cubic host minerals. Previously, reliable...
Read moreNow available: “A Grüneisen tensor for rutile and its application to host-inclusion systems”
Go have a look at the new publication on American Mineralogist by Kira Musiyachenko where she demonstrates with ab-initio calculations that pure rutile inclusions in metamorphic garnets do not develop positive residual pressures upon exhumation...
Read moreEosFit-Pinc: A simple GUI for host-inclusion elastic thermobarometry” —Reply to Zhong et al
Zhong et al. (2020) argue that the solution for entrapment conditions of inclusions presented by Guiraud and Powell (2006) is as equally valid as that proposed by Angel et al. (2017). In addition they propose a third calculation route based on...
Read moreQuartz metastability at high pressure: what new can we learn from polarized Raman spectroscopy
Quartz metastability at high pressure: what new can we learn from polarized Raman spectroscopy? Despite all the work we have done on it, quartz can still surprise us! In their new paper Marta, Boriana, Ross and Matteo characterize the Raman...
Read moreUpdated PVT Equation of State for Rutile
Updated PVT Equation of State for Rutile The conclusion of Zaffiro et al. (2019 Mineralogical Magazine, 83, 339–347) that the Mie–Grüneisen–Debye (MGD) Equation of State (EoS) cannot fit the available data for rutile is shown to be incorrect...
Read moreUsing polarized Raman spectroscopy to study the stress gradient in mineral systems with anomalous birefringence
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 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 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...
