| 摘 要： | The 2nd Member of Kongdian Formation has been made up of a large number of oil shale and mudstone in the Kongnan aera of Huanghua depression around the Bohai Bay.In the Kongnan area,the lake basins were very large and deep during the deposition of the 2nd Member of Kongdian Formation.During that period,the lakes were sealed,uncommunicated with the sea water and the paleoclimate was very warm and wet in Kongnan area.Analyzing the content of the trace element and the rare earth element,carbon and oxygen isotope in the disquisition,The authors prove the two views correct.

| Abstract: | The 2nd Member of Kongdian Formation has been made up of a large number of oil shale and mud- stone in the Kongnan aera of Huanghua depression around the Bohai Bay. In the Kongnan area, the lake basins were very large and deep during the deposition of the 2nd Member of Kongdian Formation. During that period, the lakes were sealed, uncommunicated with the sea water and the paleoclimate was very warm and wet in Kongnan area. Analyzing the content of the trace element and the rare earth element, carbon and oxygen iso- tope in the disquisition, The authors prove the two views correct. |
