Elastic Thermobarometry arrives in the Annual Review of Earth and Planetary Sciences Check out the new paper by Matt, Mattia and Matteo where they present an overview of the development of the last few years of elastic geothermobarometry...Read more
Equation of state of spinel (MgAl2O4)
Equation of state of spinel (MgAl2O4): implications for elastic geobarometry of peridotites and chromitites Spinel is potentially one of the best minerals for elastic geobarometry, but the large uncertainties in the published equation of state...Read more
Elastic geobarometry beyond simple elasticity
Resetting of zircon inclusions in garnet: Implications for elastic thermobarometry “Elastic thermobarometry of host-inclusion systems for back-calculating pressure (P) and temperature (T) conditions of inclusion entrapment relies on the...Read more
A key for understanding burial in the Scandinavian Caledonides
Deciphering the tectonometamorphic history of subducted metapelites using quartz-in-garnet and Ti-in-quartz (QuiG–TiQ) geothermobarometry In this paper, Pauline Jeanneret and co-authors characterized the tectonometamorphic evolution of the Lower...Read more
Hydrous peridotitic fragments of Earth’s mantle 660 km discontinuity sampled by a diamond
Hydrous peridotitic fragments of Earth’s mantle 660 km discontinuity sampled by a diamond “The internal structure and dynamics of Earth have been shaped by the 660 km boundary between the mantle transition zone and lower mantle. However...Read more
Can inclusions be symmetry broken?
Can inclusions be symmetry broken? Murri and co-authors recently studied the role of symmetry-breaking strains in quartz inclusions entrapped in zircon by ab initio simulations. They discovered that for deformations expected for real cases the...Read more
What can we learn from trace element and dislocations distribution in Rutile crystals?
What can we learn from trace element and dislocations distribution in Rutile crystals? Rick Verberne and Hughetto investigated the trace-element migration in low-angle boundaries formed by dislocation creep in rutile within an omphacite vein of...Read more
Looking for the next “bible” for diamond research?
Looking for the next “bible” for diamond research? “After more than 80 volumes of Reviews in Mineralogy and Geochemistry (RiMG), we now have a volume on diamond—Diamond: Genesis, Mineralogy and Geochemistry. ” Are you...Read more
Are you looking for elasticity data for garnet?
Garnet EoS: a critical review and synthesis All available volume and elasticity data for the garnet end-members grossular, pyrope, almandine and spessartine have been re-evaluated for both internal consistency and for consistency with...Read more
Characterization of carbon phases in Yamato 74123 ureilite to constrain the meteorite shock history
Characterization of carbon phases in Yamato 74123 ureilite to constrain the meteorite shock history The formation and shock history of primitive achondrites meteorites such as ureilite has been debated for decades! The characterization of carbon...Read more
Inclusions in diamonds probe Earth’s chemistry through deep time
Inclusions in diamonds probe Earth’s chemistry through deep time Most of our knowledge about the chemical composition of the Earth’s interior is primarily retrieved by indirect observations, experiments and calculations that are limited to simple...Read more
