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...
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 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 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...
Read moreThermo-elastic behavior of grossular garnet
In her manuscript Sula Milani provides for the first time consistent the thermo-elastic parameters for grossular garnet using simultaneous fitting of pressure-volume-temperature data combined with either adiabatic (KS) or isothermal bulk modulus...
