In his new paper published in Zeitschrift fuer Kristallographie Ross Angel explains the development of the past year that led to the current version of the stRAinMAN program. This allows the strains acting on inclusions trapped in their host to...

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...

Mara Murri’s proposal “Cathodoluminescence as a tool for unravelling shock features of diamonds from impact craters” has been supported for 5 days of facility time by Europlanet 2020 Research Infrastructure funding scheme for a...
Read moreDetermine strains on inclusions from Raman measurements
In her new paper published on American Mineralogist, Mara Murri, describes a method for determining the strains in quartz inclusions from Raman spectroscopy using the concept of the phonon-mode Grüneisen tensor, which we determine by ab initio...
Read moreExperimental validation of intracrystalline “geothermometry” for rocks
In this paper, we test the available experimental calibrations for clino and orthopyroxenes as geothermometer by determining their site in synthetic samples grown from a hydrous nepheline basanite in a piston-cylinder apparatus at 1050 °C at...
Read moreFinite Element modelling of stresses in inclusions by Mattia L. Mazzucchelli on Geology.
Check our our latest paper on Finite Element modelling of stresses in inclusions by Mattia L. Mazzucchelli on Geology. Elastic geothermobarometry on inclusions is a method to determine pressure-temperature conditions of mineral growth independent...
Read moreFirst evidence that Raman does not measure stresses on inclusions
Our paper on elastic barometry illustrates the difficulties related to Raman measurements on non-cubic inclusions has just been published on American Mineralogist. In her manuscript Chiara Anzolini give us an idea of the greatest source of errors...
Read moreEosFit-Pinc released
An exact solution to the problem in elastic geobarometry of combining non-linear Equations of State (EoS) with the elastic relaxation for elastically isotropic spherical host-inclusion systems without any approximations of linear elasticity is...
Read more40 Years of mineral elasticity a critical review and new equation of state for mantle olivines
The new review manuscript by Ross Angel “40 years of mineral elasticity: a critical review and a new parameterisation of equations of state for mantle olivines and diamond inclusions” has just been published online on Physics and...
Read moreContinuous phase transitions in EosFit
Continuous phase transitions in minerals, such as the α–β transition in quartz, can give rise to very large non-linear variations in their volume and density with temperature and pressure. In Angel et al 2017 we present a simplified description...
