Zircon-and bulk-rock Zr-based thermometric parameters have become fundamental to
petrogenetic models of magmatism, from which broader geochronological and tectonic …

Significant volume of wet melting requires an influx of H2O-rich volatile phase. In hydrate-
breakdown melting, initial melt accumulation is diffusion-controlled and melt accumulates …

The Th/U ratios of zircon crystals are routinely used to help understand their growth
mechanism. Despite the wide application of Th/U ratios in understanding the geological …

At low temperatures (< 750 C at moderate to high crustal pressures), the production of
sufficient melt to reach the melt connectivity transition (∼ 7 vol%), enabling melt drainage …

Concordant U–Pb zircon dates have been interpreted traditionally to date the crystallization
ages of plutons because until recently analytical uncertainties have generally been large …

Zircon geochronology and geochemistry are increasingly important for understanding
metamorphic processes, particularly at extreme conditions, but drivers of zircon dissolution …

Ages retrieved from accessory minerals in high-grade metamorphic rocks place important
constraints on the timing of events and the rates of tectonometamorphic processes operating …

Zirconium and Hf are nearly identical geochemically, and therefore most of the crust
maintains near-chondritic Zr/Hf ratios of~ 35–40. By contrast, many high-silica rhyolites and …

U–Pb age data collected from zircon and monazite are used to draw fundamental inferences
about tectonic processes in the Earth. Despite the emphasis placed on zircon and monazite …

Abstract Hafnium, U, Th, and REE content of zircons from the Spirit Mountain batholith in
southern Nevada correlate with calculated temperatures from the Ti-in-zircon thermometer to …
