摘要
Mesozoic volcanic rock areas of Da Hinggan Mountains have been covered by plants,and its contact relationship of the stratigraphic units was unknown with less of paleontological chronology material,which makes it very hard to determine the ownership and forming times of geological units. Traditionally, we classify the stratigraphic units of this area by contrasting rocks combination and often give different names for the same mapping unit because of limited cognition. In this article,we firstly introduced the evolution history of Mesozoic volcanic stratigraphic units contrasts of Da Hinggan Mountains,secondly compared the stratigraphic units and set based on stratigraphic column which was put forward by Zhang Lidong in the Mesozoic volcanic stratigraphic units discussion meeting which was called by the geological survey of China in the city Chengde. According to the theory of bi-model volcanic origin and evolution and the latest chronology measurement means,such as U-Pb、Ar-Ar and others,we put forward new stratigraphic column and divided it into three stages of early,middle and late,which complied with the naming rule of stratigraphy priority.
