지질학적 요약
The Longgang volcanic field covers 1,700 km2 in the Jilin Province of NE China. Basaltic and trachybasaltic lava flows cover a large area containing more than 150 Quaternary cinder cones and eight tuff rings. There is only one known cinder cone of Holocene age, Jinlongdingzi (Gold Dragon Peak); the eruption formed the large scoria cone and deposited tephra over a broad area to the E which was radiocarbon dated at about 1,600-1,700 years ago.
