Understanding of secular evolution of the Earth system is based largely on the rock and
mineral archive preserved in the continental lithosphere. Based on the frequency and range …

If we accept that a critical condition for plate tectonics is the creation and maintenance of a
global network of narrow boundaries separating multiple plates, then to argue for plate …

The Earth as a planetary system has experienced significant change since its formation c.
4.54 Gyr ago. Some of these changes have been gradual, such as secular cooling of the …

Phosphorus (P) is critical to modern biochemical functions and can control ecosystem
growth. It was presumably important as a reagent in prebiotic chemistry. However, on the …

Reconstructing Earth history during the Hadean defies the traditional rock-based approach
in geology. Given the extremely limited locality of Hadean zircons, some indirect approach …

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 …

Under modern oxidising Earth surface conditions, dehydrated subducted slabs show Mo
isotope compositions as low as δMo=− 1.5%, compared to the depleted mantle δMo …

Mo isotope compositions have been increasingly used as a source tracer in magmatic
systems. Here, we investigate the relative role of subducting oceanic crust, fluid-rich sources …

Arc volcanic rocks erupted above oceanic subduction zones generally have heavy
molybdenum (Mo) isotopic compositions, which are attributed to contributions from oceanic …

Several studies have suggested that the Earth's upper mantle is slightly enriched in light
molybdenum isotopes relative to bulk Earth, defined by chondrites, but there is no …
