URANIUM-SERIES DATING OF YOUNG GEOLOGIC BODIES

Ye Huadong |Wu Zhenyuan| Wen Xiaosheng (Laboratory of the South China Sea Headquaters of Geological Investi gation, Ministry of Geology and Mineral Resources)  
Based on the fact that in young geologie bodies a disequilibrium state is existed between the daughter products and the parents of uranium and thorium isotopes, the uranium series dating methods suitable for dating young geologie bodies was established. With this method, the age of the rocks and sediments ranging from tens to hundreds thousand years can be determined, so it is useful in solving oceanographic, Quaternary and other geological problems. In tbis paper, the experimental method including the chemical treatment of samples (separation and purification of uranium), the preparation of U, Th sources, the energy-spectrum measurement and the handling of measured data and so on are described in detail. In addition, the data of the uranium series standard samples of the national project in 1983 measured in our laboratory are also discussed. The data of carbonate samples provided by the Beijing Institute of Geological Investigation and the data of the Guilin stalagmites measured by us are listed. The results indicated that the dating values of the carbonate samples with the uranium-series method are reliable.
