| 摘 要： | 1IntroductionThe Shansonggang Basin, one of the Mesozoic coal-bearing basins in northeastern China, is located in southern Jilin Province, China and covering about 30 km2(Fig.1). The basin is lying in the northwest-ern margin of the Longgang anticline, just opposite to the Yihe Basin which lies in the southeastern margin of the anticline. During 1940s~1970 s, a lot of work on the survey of coal geology was made in the basin, but there has been a little knowledge about the plant fossils…

| Abstract: | More than 35 species belonging to 22 genera of fossil plants are recognized by the authors from the Shan-songgang flora in the Shansonggang Basin of Jilin, China. Among them, the coexistence of Coniopteris and Cycadocarpi-dium demonstrates that the present flora possesses the characters of the early assemblage of Early Jurassic floras in Eura-sia. Therefore, the age of the Shansonggang flora is considered the Early Jurassic.This study would be beneficial for bet-ter understanding the paleoecological and paleoclimatic characteristics of the Shansonggang Basin. Based mainly on the characters of the flora, the authors suggest that the Lower Jurassic coal-bearing strata, the Shansongang Formation, should namely be renewed. |
