Multifractal Characteristics of Uranium Grade Distribution and Spatial Regularities in a Sandstone Type Uranium Deposit in Xinjiang, China

Fractal and Fractional, 2023
Based on the analysis of the spatial distribution of uranium grade in 348 boreholes of a uranium deposit in Xinjiang, the enrichment and spatial variation of uranium ore in two stopes of the deposit are discussed by using multifractal theory. The distribution characteristics of uranium ore of the two stopes are studied by multifractal parameters: the ...

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). However, due to complex occurrences of sandstone-type U deposits, high requirements for laser ablation during in situ dating, and
