RECENT ADVANCE IN STUDY OF EARLY CRETACEOUS BIOSTRATIGRAPHY FROM JIXI COAL-BEARING BASIN,HEILONGJIANG,CHINA

Recently,the new discoveries of the Early Cretaceous marine dinoflagellates and early angiosperms from Jixi coal-bearing basin in the eastern Heilongjiang,China have documented that the coal-bearing Jixi Group,consisting(ascendingly)of the Didao Formation,Chengzihe Formation and Muling Formation, aged in Early Cretaceous. The Palaeogeographic framework of the eastern Heilongjiang in Late Mesozoic era is rebuilt through marine and paralic biostratigraphic analysis,which provided new fundametal data for widening coal searching prospect.
