In order to investigate the mechanism of uranium accumulation in the Kupferschiefer, 88 samples from 10 sections were analysed by geochemical method. The results indicate that the higher uranium contents originated from and are transported from the underlying Rotliegendes into the Kupferschiefer by oxidized brines, and then precipitated when they encountered the organic matter, which occurred as reductant, in the Kupferschiefer.
