The Pleistocene Nangelaqiushan scoria cone contains a 500-m-wide flat-bottomed crater, is one of many cones forming the Wudalianchi volcanic field in Manchuria, NE China. The cones show a preferred alignment along three parallel NE-SW trends. The Wudalianchi volcanic field was named for five scenic lakes dammed by lava flows during a 1719-21 eruption, which formed two new scoria cones and produced a 65 km² lava field.
