Titanium isotopes as a tracer for the plume or island arc affinity of felsic rocks
Indirect evidence for the presence of a felsic continental crust, such as the elevated
49Ti/47Ti ratios in Archean shales, has been used to argue for ongoing subduction at that …

Dominance of felsic continental crust on Earth after 3 billion years ago is recorded by vanadium isotopes
The transition from mafic to felsic upper continental crust (UCC) is crucial to habitability of
Earth, and may be related to the onset of plate tectonics. Thus, defining when this crustal …
