Since the start of the 21st century, the widespread application of ion probes has promoted the mass output of high-precision and high-accuracy U‒Th‒Pb geochronology data. Zircon, as a commonly used mineral for U‒Th‒Pb dating, widely exists in the continental crust and records a variety of geological activities.
