#Zircon doesn't just keep time; it can record temperature too. The image is of a ~4mm zoned zircon crystal from the Bancroft-area of Ontario (Grenville-age granulite metamorphics). The trenches are 40 and 60 microns wide, created by laser-ablation #ICPMS analyses.

~3.5 parts per million titanium corresponds to crystallization temperatures of ~ 675°C (plus or minus a lot, unfortunately, in this case).

#Neptunite is one of a few calcium-free titanium silicates (incl. benitoite). Seems like an obscure fact but:

#Zircon includes titanium in its structure, as a function of temperature; this can be a #geothermometer.

To standardize a microbeam analysis (like laser ablation ICPMS), we need a mineral with a known composition, lots of titanium and silica and no calcium, which has an isotope at mass 48. Neptunite and benitoite are perfect for this.
