Monazite geochronology
Videos
Monazite geochronology is a dating technique to study geological history using the mineral monazite. It is a powerful tool in studying the complex history of metamorphic rocks particularly, as well as
Range of geological processes at different temperature recorded by monazite, zircon and apatite in U-Pb dating
Sample preparation: Thin sections of limestone rocks
Monazite identification: Illustration showing a backscattered electron image of a rock sample with monazite (at the center with white color). Edited after Williams, 1999.
Quantitative dating: Histogram of ages measured, showing two age zonations in monazite. Edited after Williams, 1999.
