UNDER THE VOLCANO. UNVEILING MAGMA HISTORIES WITH MICROANALYSIS
Seminars
Teresa is a volcano petrologist at The University of Queensland. She develops high-resolution geochemical techniques to interrogate magmatic crystals and their carrier melts, providing a better understanding of magma transport and storage through the Earth’s upper mantle and crust. Her research constrains magmatic processes in space and time, with a particular focus on the drivers of volcanic eruptions and the processes that lead to the accumulation of metals that are critical for the green energy transition.
Teresa is an ARC Future Fellow and was awarded the 2023 Anton Hales Medal from the Australian Academy of Science.
Magma storage modulates the explosivity, frequency, and impact of volcanic eruptions, and controls the formation of magmatic-hydrothermal mineral deposits. The architecture of magma storage and plumbing systems, and their eruption triggering mechanisms,
are inaccessible to direct observation in active volcanoes. However, they can be accessed through the study of volcanic products, particularly by isolating the crystal and melt records they contain. This talk will explore high-resolution geochemical techniques to extract pre-eruptive histories from crystal cargoes, and syn-eruptive information from the carrier melts. We will investigate magma-mush storage systems feeding volcanism, and their implications for volcano monitoring and finding critical metals from the green energy transformation.
