We undertook Zr isotope measurements on zircon, titanite, biotite, amphibole, and whole rocks from the La Posta pluton (Peninsular Ranges, southern California) together with trace element analyses and U-Pb age measurements to understand the controls

Tectonic deformation can influence spatiotemporal patterns of erosion by changing both base level and the mechanical state of bedrock. Although base-level change and the resulting erosion are well understood, the impact of tectonic damage on bedrock

We show that the existence and evolution of the geodynamo before 3.5 Ga ago remains unknown.
The time of origin of the geodynamo has important implications for the thermal evolution of the planetary interior and the habitability of early Earth.

Magmatic zircon tends to exhibit characteristic trends in trace element contents in response to magma cooling and fractionation, such that zircon may provide a window into melt evolution not accessible by whole rock geochemistry. The Peninsular Range
