An andesitic source for Jack Hills zircon supports onset of plate tectonics in the Hadean
© 2020 Crown. The composition and origin of Earth’s early crust remains hotly debated. Here we use partition coefficients to invert the trace element composition of 4.3–3.3 Gyr Jack Hills zircons to calculate the composition of the melts from which they crystallised. Using this approach, the ave...
