A Windows program for pyroxene-liquid thermobarometry
Periodico di Mineralogia, 2018 A Windows program (WinPLtb) has been developed to calculate wet–chemical and microprobe pyroxene analyses based on the standard International Mineralogical Association (IMA-88) nomenclature scheme. The program allows the user to enter clinopyroxene, orthopyroxene and associated composition of liquid or whole-rock and some calculated components in the

EosFit-Pinc: A simple GUI for host-inclusion elastic thermobarometry
American Mineralogist, 2017 Elastic 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 ...

Annual Review of Earth and Planetary Sciences, 2023 Upon exhumation and cooling, contrasting compressibilities and thermal expansivities induce differential strains (volume mismatches) between a host crystal and its inclusions. These strains can be quantified in situ using Raman spectroscopy or X-ray diffraction.

Journal of Metamorphic Geology, 2023 AbstractEclogite thermobarometry is crucial for constraining the depths and temperatures to which oceanic and continental crust subduct. However, obtaining the pressure and temperature (P–T) conditions of eclogites is complex as they commonly display high‐variance mineral assemblages, and the mineral compositions only vary slightly with P–T.

Anais da Academia Brasileira de Ciências, 2021 The Tamboril and Olho d’Água granitic stocks are part of the abundant calc-alkalic magmatic epidote-bearing granitic rocks in the Cachoeirinha–Salgueiro Terrane (CST) in the Transversal Zone Domain, northeastern Brazil. The equigranular Olho d’Água stock
