In situ U-Pb Isotope Dating Techniques for Sandstone-type Uranium Deposits

Yankuang ceshi, 2020
BACKGROUND Uranium mineral dating has been difficult to ascertain in mineralization chronology. With the development of in situ U-Pb isotope dating technology, it is possible to directly date ore minerals (uranium minerals).

Determination of Trace Rhenium in Sandstone-type Uranium Deposits by Inductively Coupled Plasma-Mass Spectrometry with Magnesium Oxide Sintering

Yankuang ceshi, 2016
The average content of uranium in sandstone-type uranium deposits is 635 μg/g, whereas the content of rhenium is 0.3-1.9 μg/g. Because of low rhenium content, now precise determination of low Re in high U ores remains unresolved.
