Lithology and Thickness
The Huangbanji Formation is dominated by metamorphosed siltstone, slate and sandstone intercalated with local schistose acid tuff, with a coarser clast and a lower metamorphism in the upper part, representing a shallow marine terrigenous sedimentation. In the type area, the formation is about 300 m.
Relationships and Distribution
Lower contact
It rests conformably on the Kunasenhe Fm
Upper contact
The contact relationship between the Huangbanji Fm and the overlying strata is not known owing to the intrusion of plagiophyre. Regionally, the next younger unit is the Dayixikanghe Fm.
Regional extent
The Huangbanji Fm is exposed in Huangbanji and the junction area of the Kunasen River and the Neiwolegen River.
