摘要
This paper presents a comprehensive analysis about lithological association,zoolite and plant fossil assemblage and sporo-pollen assemblage..The conclusions are as follows: 1) the Benxi Formation in Hebi of North Henan Province is a lithostratigraphic unit that spans across the Huashiban stage and Dalat stage; 2) the upper limit of the Benxi Formation in Jiaozuo City is near the upper limit of the Dala stage; 3) the Benxi Formation in West Henan Province is a lithstratigraphic unit cutting across the Huashiban stage,Dalat stage and Maping stage; 4) the biological group in the Benxi Formation of the North Songqi area is the product of the late Carboniferous epoch; and 5) the biological group in the Benxi Formation of the central Songqi area is later than that in the north Songqi area.
