| Abstract: | The Devonian System of Jilin, which was rarely known in the past,is now tentatively divided into the following stratigraphic units before further work is clone: the lower Middle Devonian (Eifelian) Wangjiajie Formation, the upper Lower Devonian (Emsian) Jiancaodianzi Formation and the Lowermost Devonian (Lochkovian) Erdaogou Formation. The upper part of the metamorphic Hulan Group belongs to the Middle Devonian. |
