Abstract A set of Late Paleozoic strata, dominated by acid-intermediate volcanic lava, is outcropped around the Nenbei Farm in Daxinganling region. Previously, the stratigraphic division and age of the strata have been great differences. The reasons for this are as follows: On the one hand, the volcanic rocks in the area are great in thickness, discontinuously outcropped and covered by vegetation, with top and bottom mostly contacted with faults or covered with Quaternary sediments. On the other hand, there is less fossils in the volcanic rocks, or lack of precise isotopic geochronological data. Based on recent research results and comparison between the rock assemblages on zircon U-Pb geochronology, these Late Paleozoic strata are reassigned.
