A newly compiled global database of uranium, lead, and oxygen isotopic analyses of zircon shows temporal changes in the magmatic record related to changes in the degree of crustal reworking. The delta-18O composition of bulk sediment remains relatively constant through geologic time. In contrast, the delta-18O values in magmatic zircons go from relatively low values in the Archean to increasingly higher and scattered values defining a series of peaks and troughs in post-Archean data wherein peaks of crustal reworking increases is associated with supercontinent assembly. Hence we attribute the pattern of post-Archean delta-18O values recorded by magmatic zircons to the onset of collisional tectonics, especially during formation of supercontinents.


Complex mineral zoning patterns caused by ultra-local equilibrium at reaction interfaces
Stacey Borg et al., CSIRO Earth Science and Resource Engineering, P.O. Box 1130, Bentley, 6102 Western Australia, Australia. Published online 21 Mar. 2014; http://dx.doi.org/10.1130/G35287.1 Open Access.

Chemically zoned minerals are useful records of ambient conditions and bulk chemical composition of the fluid from which the minerals precipitate. In fluid-buffered systems, zoning of mineral compositions is expected to reflect directly the evolution of fluid composition. This study shows that during rapid fluid-rock reactions, ultra-local equilibrium can form complex mineral zoning patterns, even when the overall system is highly fluid buffered. Stacey Borg and colleagues reacted cleaved calcite single crystals with aqueous arsenat
