EosFit-Pinc: A simple GUI for host-inclusion elastic thermobarometry
American Mineralogist, 2017Elastic geothermobarometry is a method of determining metamorphic conditions from the excess pressures exhibited by mineral inclusions trapped inside host minerals. An exact solution to the problem of combining non-linear Equations of State (EoS) with the elastic relaxation problem for elastically isotropic spherical host-inclusion systems without any ...

Journal of Metamorphic Geology, 2008
AbstractThermobarometry, the estimation of the pressure–temperature (P–T) conditions of metamorphism, can be undertaken by using pseudosection calculations as well as by conventional methods. Conventional thermobarometry uses only the equilibrium thermodynamics of balanced reactions between end‐members of minerals, combined with the observed ...

The valence state of iron in mantle-derived melts, such as mid-ocean ridge basalt, is a useful proxy for oxygen fugacity (ƒO2). On subduction, oceanic crust undergoes metamorphic reactions that alter its initial ƒO2, generating compositional and redox ...

Reconstruction of the Talkeetna intraoceanic arc of Alaska through thermobarometry [PDF]
Journal of Geophysical Research, 2008 The Talkeetna arc is one of two intraoceanic arcs where much of the section from the upper mantle through the volcanic carapace is well exposed. We reconstruct the vertical section of the Talkeetna arc by determining the (re)crystallization pressures at various structural levels. The thermobarometry shows that the tonalites and quartz diorites intruded

Thermobarometry in granulites: pitfalls and new approaches
Precambrian Research, 1992Abstract Computer models of cooling granulite-facies rocks with the assemblage garnet+biotite+sillimanite+K-feldspar±plagioclase+quartz are presented that incorporate simultaneous reaction (net transfer and exchange) and multicomponent diffusion in garnet.

Clinopyroxene in postshield Haleakala ankaramite: 1. Efficacy of thermobarometry
Contributions To Mineralogy and Petrology, 2015Magma storage depth is a fundamental aspect of a volcano’s magmatic plumbing system that may be resolved using mineral-melt thermobarometry, assuming crystal growth occurs at near-equilibrium conditions. We acquire major and minor element compositional analyses of whole rock, groundmass separates, and clinopyroxene in ankaramite erupted ca.
