Spectroscopic analyses of mineral inclusions for petrologic investigations

Session ID#: 28904

Session Description:
Inclusions of minerals trapped within other mineral grains provide a sensitive record of the conditions and microenvironment in which the host mineral grew. Understanding how this environment varied during growth is crucial for developing tectonic models, identifying chemical disequilibrium, unraveling igneous processes, and deciphering crust and mantle dynamics. This session is dedicated to the application of high-resolution spectroscopic methods (e.g., x-ray diffraction, micro-Raman, Fourier transform infrared spectroscopy) to mineral inclusions in igneous and metamorphic rocks, in order to interrogate geologic processes from the shallow crust to the deep mantle. We encourage submissions that utilize mineral (as well as fluid and melt) inclusions to decipher perturbations in pressure and/or temperature during mineral growth, and to assess fluid flux and transport. Submissions that integrate petrologic constraints with structural, deformation, and/or temporal (absolute and relative) context are highly encouraged.
