Proterozoic onset of crustal reworking and collisional tectonics: Reappraisal of the zircon oxygen isotope record
A global U-Pb and δ18O zircon database shows temporal changes in the magmatic record related to changes in the degree of crustal reworking. The δ18O composition of bulk sediment remains relatively constant through geologic time, with a mean value of 14.9‰. In contrast, the δ18O values in magmatic zi...
