Abstract: The relationships between Huanan uplift and its surrounding basins, such as Sanjiang Basin, Hulin Basin, Boli Basin, Jixi Basin, Shuangyashan Basin and Shuanghua Basin，are playing an important role in the regional oil and gas resources exploration and development. The researches of regional stratigraphic correlation, marine fossils, basin boundary faults and geophysical MT profile suggest that these basins experienced the same evolution, and underwent one or more transgressions during Chengzihe and Muling Formations. The present basin boundary thrust faults and geophysical MT profiles crossing the basins and Huanan-uplift show that the present isolated basins belonged to a large-scale epicontinental offshore basin (Sanjiang-Muling Basin) during the period of Chengzihe and Muling Formations. Meanwhile, the Huanan uplift did not develop. Base on the directions of paleocurrent, sandstone provenance analysis and gravel composition statistics, it reveals that Huanan uplift were uplifted after the depositing of Dongshan Formation, and supplied the sediments for the surrounding basins during the period of Houshigou Formation, and the present basin-range topography appeared in the northeastern Heilongjiang Province.

Key words: northeastern Heilongjiang Province, Huanan uplift, Sanjiang-Muling Basin, Houshigou Formation
