Popis:	Laser micro-area analysis40Ar-39Ar isochron dating for pure alunite is first reported. Microarea40Ar-39Ar isochron dating results revealed that the metallogenetic epoch of Fanshan superlarge alunite deposit is 74.50 Ma, and this age is 10–20 Ma later than that of regional volcanic activity. Moreover, the potential application of micro-area analysis40Ar-39Ar isochron dating method in metallogenetic epoch studies for nonmetal deposits is also discussed.
