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岩系在空间上呈指状交互关系。根据植物化石确定南大岭组时代为早侏罗世。论述火山岩岩石学、岩石化学特征。 Based on the latest data, the stratigraphic sequence, lithology, rock assemblage and sedimentary structure of the four measured sections of the Nanlingling Formation in Shanggu, Chengde are described. It is determined that the Nan Da Ling Formation is a set of middle-basic volcanic rock series. The sedimentary rock series as an informal mapping unit confirm that the volcanic rock series and sedimentary rock series are in a finger-like spatial relationship. According to plant fossils, the age of the Southern Da Ling Formation was Early Jurassic. Discussion on volcanic petrology and petrochemistry.
