In situ location and U‐Pb dating of small zircon grains in

This paper describes a new, automated, in situ zircon location method and a 10 μm spot size LA-ICP-QMS analysis method that measures U-Pb ages in small zircon grains. The method is rigorously tested on a well characterized rhyolite and is then demonstrated on dolerites and

Zircon saturation in silicate melts: a new and improved

Feb 24, 2016The WH83 zircon saturation model has been widely used in geochemistry and geochronology, mainly to estimate temperatures of magmas. However, it can also be employed as a tool to predict the proportion of original zircon that remained in the unmelted source, in this way helping to understand the trace elements distribution in magmas (Watson and Harrison 1983).

Zircon

Zircon is very common and widely distributed in the Earth's crust. It is found in most igneous and metamorphic rocks; however, it may not be noticed because of its very small particle size. Due to its hardness and durability it does not weather easily, so is also found in sedimentary deposits and is a common constituent of most sands.
