| 摘 要： | 利用最新资料描述了承德上谷南大岭组四个实测剖面的地层层序，岩性岩石组合，沉积构造等特征，厘定了南大岭组含义为一套中基性火山岩系，其间的沉积岩系作为非正式填图单位，证实了火山岩系与沉积系在空间上呈指状交互关系，根据植物化石确定南大岭组中时代为早侏罗世，论述火山岩岩石学，岩石化学特征。

| Abstract: | Vsing the latest research data the authors desoribe the stratigraphic sequences,lithology,rock organization and sedimentary stnutures of four measured section of the Nandaling Formation in Shanggu of chengde Revising the Nandaling Formation is a sequence of intermediate-basic volcanic rocr system and sedimentary rock system is formal right mapping units. The author has verified that the volcanic rock ststem and sedimentary rock system are fingers and fingers relation in the space According to its fossil plants,determined the Nandaling Formation to be of Early Jurassic age,representing petrology and petrochemical features of volcanic rock |
