In the framework of the ARC Discovery Project titled “A terrestrial hot spring setting for the origin of life?” I am investigating the geological, geochemical, and metallogenic aspects of a 3.5 billion-year-old hot spring setting in the Pilbara region of Western Australia. This work aims at understanding the 4-dimensional evolution of the Dresser Caldera in relation to element mobility within the hydrothermal fluids. To achieve this goal I am examining the alteration imparted by hydrothermal fluids to the host-rocks through a combination of field observations, whole-rock, XRD, and stable lithium and boron isotope analyses of newly collected samples, which have been integrated with previously published hyper-spectral maps, and fluid inclusion data. This large and multi-disciplinary dataset will be translated into a holistic model able to constrain the processes that allowed metals and other elements to be mobilised, and develop the conditions for early forms of life to form and thrive.
