| 摘 要： | 笔者对腮林忽洞组的岩石地层特征、层序地层、生物(叠层石)地层进行了深入研究。将腮林忽洞组划分为4个岩性段、7个三级层序;根据叠层石组合特征,建立了3个叠层石组合;结合前人获得的两件同位素年龄(207Pb/204Pb)数据,认为腮林忽洞组的时代应归属中元古代长城纪—蓟县纪。

| Abstract: | The present paper gives a detailed discussion about the lithostratigraphy,sequence stratigraphy and biostratigraphy（stromatolitic stratigraphy） of the Sailinhudong Formation in the Damaoqi region,Inner Mongolia,and separates the Sailinhudong Formation into four lithological members,seven third-order sequences and three stromatolitic assemblages.According to the existing 1：50 000 regional geological survey and mineral exploration,in reference to the previous data,especially the isotopic ages of 1456 ± 69 Ma and 1283 ± 59 Ma,the authors in this study contend that the Sailinhudong Formation should be traced back to the Changchengian to the Jixianian of the Mesoproterozoic. |
