摘要
The principles of U-Pb isotope dating, the advantages and limitations of minerals for dating, several dating methods and the basic principles of selection for minerals and methods of U-Pb dating are discussed based mainly on studies, combined with references recently reported. The potential prospects are discussed for applying in geology. The studies show that the different minerals for dating and different methods of U-Pb dating have different characteristics and limitations. It is very important to select minerals for dating and methods of U-Pb dating according to the mineral content, grain size, age range, U-Pb content and dating precision requirement of the samples to get relatively ideal results.
