摘要：

The comparison of Pb isotopic compositions for Various ores and rocks has revealed that the lateral variation between different terranes is greater than the vertical variation between crust and mantle, which is useful for geochemical mapping. Based on a three dimensional topological diagram of ph isotopes, six geochemical provinces can be recognized in China, namely southern China, Yangtze, northern China, northern Xinjiang, Jiamusi and Tibet. The application of Pb isotopes to regional mapping provides important background data for geochemical prospecting as it establishes the tectonic boundaries of terranes and identifies the source regions of mineralization, magmatism and sedimentation. It also provides information on the origin of pollution and cultural relies.
