Extensive fluid‐rock interaction and pressure solution in a UHP fluid pathway recorded by garnetite Lago di Cignana, Western Alps Fluids released by dehydration reactions in subducting slabs can result in dissolution and related mass transfer...
Read moreGarnet sand reveals rock recycling processes in the youngest exhumed high- and ultrahigh-pressure terrane on Earth
This recent publication by Baldwin et al., in collaboration with new lab group member Joseph Gonzalez studied inclusion bearing detrital garnets from the actively exhuming (ultra)high-pressure terrane in eastern Papua New Guinea. Individual...
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 moreImpact shock origin of diamonds in ureilite meteorites
The origin of diamonds in ureilites is still a debated issue among the scientific community, with significant implications for the sizes of early Solar System bodies. We investigated three diamond-bearing ureilites by a multimethodological...

Commensurate Growth of Magnetite Microinclusions in Olivine under Mantle Conditions In this latest paper Campione Malaspina and co-workers provide evidence that points to a clear epitaxial growth of magnetite on olivine in a particular...
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...
