U-Pb Isotopic Dating of Monazite in Granite from the Changjiang Uranium Orefield, Northern Guangdong Province and Its Geological Significance

Yankuang ceshi, 2022
BACKGROUND The Changjiang uranium ore field in the southern margin of the Zhuguangshan complex pluton is a typical granite-type uranium ore field in China. Zircon U-Pb dating has been used to date ore-bearing granites. However, due to the high content of

NanoSIMS and EPMA dating of lunar zirconolite

Progress in Earth and Planetary Science, 2021
Zirconolite is a common Zr-rich accessary mineral in mafic rocks. It is also an ideal U–Pb/Pb–Pb chronometer because it commonly contains high U content (mostly 0.1–10 wt%) and negligible initial Pb.
