Zircon (ZrSiO4) is arguably the most valuable mineral in the geosciences today. Whilst that might be debatable (diamonds for example, are extremely important to our understanding of the mantle), there is no doubt zircon is in the top five of minerals that, without, our understand of the Earth, Moon, and solar system, would be quite different. Why is zircon so special? First of all, it is common in rocks of the Earth’s crust (intermediate to felsic rocks anyway), forms readily as an accessory mineral in igneous and high-grade metamorphic rocks, and is extremely resistant to chemical diffusion, alteration, and crystallisation, forming an extremely durable chemical ‘time-capsule’. The chemical structure of zircon also allows substation of many useful trace elements. Zircon’s most important use has been as a geochronomter. Uranium partitions into the crystal structure, and using standard radioactive decay law, we can calculate the age of the zircon one we know the radiogenic Pb concentrations. This has enabled us to date rocks across the Eons and is still our most widely used and trusted dating method. Zircon also offers additional isotopic and chemical tools. Hf isotopes tell us about the age of crust components involved in magmatic events, and O-isotopes tell us about involvement of surface components. Trace elements have been used to inform us on hydration and oxidation of magmas, as well as their igneous and metamorphic petrogenesis. In this study, we will be using the durability and persistence of zircon in these Archean volcanics to inform us on the age of any contaminating component (crust? Lithosphere?) using hafnium isotopes, and most importantly oxygen isotopes to search for a surface component in the source of this large igneous province. The results could give us clues into tectonic settings in the early Earth, and their effect on large-scale magmatic events. .
