dc.description.abstractDetermination of the pressures and temperatures at which rocks form is crucial to understanding petrologic processes in Earth. Elastic thermobarometry is a new, simple, technique that has shown early potential to accurately constrain the temperature and pressure conditions of rock formation using only low-cost Raman spectroscopy. Here, I performed the first crustal-scale application of elastic thermobarometry to demonstrate its extent and limitations. I applied elastic thermobarometry on metasedimentary and igneous rocks along two transects through the crustal section at Sierra Valle Fertil – La Huerta, Argentina. Quartz-in-garnet in migmatites recovers pressure ranging from 120 to 1374 MPa. Zircon-in-garnet thermometry from the same rocks estimates temperatures between 623 to 1512 °C. Finally, I evaluated possible applications on inclusion-host systems from igneous, marble, and metasedimentary rocks. My work shows that elastic thermobarometry can be a useful tool in combination with other techniques, but I encountered limitations when applied to high temperature rocks.
