Zircon ages in granulite facies rocks: decoupling from geochemistry above 850 °C? [PDF]

, 2018
Granulite facies rocks frequently show a large spread in their zircon ages, the interpretation of which raises questions: Has the isotopic system been disturbed? By what process(es) and conditions did the alteration occur?
