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（207 Pb/204 Pb）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。

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.
