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?

Apatite U-Pb dating at UNAM laboratories: analytical protocols and examples of its application

Revista Mexicana de Ciencias Geológicas, 2019
Apatite is the most common phosphate mineral in the Earth’s crust and can be found in practically all magmatic and metamorphic rocks, as well as in ancient and recent sediments and in certain ore deposits. Its effective closure temperature of 450–550 °C
