Elastic Geobarometry for Anisotropic Inclusions in Anisotropic Host Minerals: Quartz?in?Zircon

Current models for elastic geobarometry have been developed with the assumption that host and/or inclusion minerals are elastically isotropic. This has limited applications of thermobarometry to mineral inclusions contained in cubic quasi-isotropic (e.g., garnet). Here, we report a new model takes into account anisotropic properties and relative crystallographic orientation (RCO) host-inclusion system where both noncubic. can be used thermobarometric calculations provided RCO known. We then this numerically evaluate effects anisotropy on strains stresses quartz entrapped zircon after exhumation from known entrapment P-T conditions room conditions. conclude quartz-in-zircon is suitable may widely applicable crustal rocks. Our results demonstrate isotropic cannot determine entire strain state an mineral, therefore lead errors estimated remnant pressures.
