BackgroundTwo adjacent volcanic cones are located just NE of the city of Kedong in the Heilongjiang Province of far northeastern of China. The larger eastern cone is about 700 m in diameter, and the smaller western one is 600 m. A third circular feature about 200 m in diameter forms a very low (12 m high) hill about 1 km NW of the western cone. Zhao and others (2014) reported a date of 0.43 +/- 0.01 Ma for the north cone, and noted that Liu and others (2001) had dated the east cone at 0.563 +/- 0.133 Ma.
