Position Description: The first half-billion years of Earth history (the Hadean Eon) are as mysterious as they are controversial. We don’t even know yet when plate tectonics started and when the first continents formed. Due to the absence of a rock record, we can only directly study this time period through the mineral zircon. However, there are only a dozen locations around the globe where such old zircons have been found. In this project, you will study Hadean and Archean zircons from South Africa to understand what types of rocks these minerals came from, how far the zircons have been transported, and what they can tell us about early tectonic processes. You will search the literature for appropriate model melt calculations, use the geochemistry of the Hadean and Archean zircons to calculate the compositions of the melts the zircons crystallized from, do size and shape analyses of the zircons, and compare the results to modern and ancient rocks.
