摘要
利用“八五”期间开展的１∶５万区域地质调查获得的新资料，确认了辽西三十家子盆地张家口组的存在，就其岩相类型、岩石组合特征、时代归属、与上下地层之间的接触关系等问题进行了论述。并探讨了张家口组的建立对冀北辽西中生代岩石地层单位划分与对比的地质意义。
According to new information obtained from 1∶50 000 regional geological survey carried out during the Eighth Five Year Plan period, the authors confirm for the first time the existence of the Zhangjiakou Formation in the Sanshijiazi basin, western Liaoning and discuss such problems as the types of rock facies, features of rock associations, age assignment and contact relationships between the overlying and underlying strata.
