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

open access: yesYankuang 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

open access: yesProgress 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.

Geochemistry and geochronology of Carboniferous volcanic rocks from the Edren range, Trans-Altai Zone, SW Mongolia

open access: yesMongolian Geoscientist, 2022
The Edren range of the Trans-Altai zone is situated in the central south part of the Central Asian Orogenic Belt. The Edren range is composed primarily of volcano-sedimentary rocks that were weakly metamorphosed during the Devonian to Carboniferous ...
