Jingpohu is a Pliocene-to-Holocene volcanic field in the Jingpo Lake area of Heilongjiang Province, NE China. The lake formed when lava flows blocked the Mudan River (Mudanjiang). The NE-striking Dunhua-Mishan fault controls the location of many vents. One alkali basaltic lava flow traveled 100 km down a canyon NW of the lake. Many Holocene trachybasaltic or basanitic cones and lava flows lie on plateaus along the Mudan River, which also contain basanitic and tephriphonolitic rocks. Mantle xenoliths are common. A period of major activity about 5,500-5,200 years ago produced extensive lava flows that covered an area of about 500 km2.
