stRAinMAN software now released

stRAinMAN software now released

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...

Strain release after polishing

Strain 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...

Determine strains on inclusions from Raman measurements

Determine 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...

Experimental validation of intracrystalline “geothermometry” for rocks

Experimental 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...

First evidence that Raman does not measure stresses on inclusions

First 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...

Continuous phase transitions in EosFit

Continuous 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...

Thermo-elastic behavior of grossular garnet

Thermo-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...
