| Abstract: | The latest isotope age data from the Proterozoic metamorphic rocks in northern Jiaodong are reported which has led the author to conclude that:the Jingshan Group and the Fenzishan Graup should be considered to be synchronous but heteropical-facies products; the Zhifu Formation should be seperated from the Fenzishan Group and promoted to a separate group. Meanwhne, the age of the Penglai Group is also discussed. |
