Geological Summary

The recently discovered Arshan volcanic field in the central Da Hinggan Mountains of Inner Mongolia in NE China, contains more than 40 Cenozoic volcanoes. The youngest cones, including Yanshan and Gaoshan, are perfectly preserved and produced basaltic lava flows that blocked drainages of the Halahale River and created six lava-dammed lakes. Radiocarbon dates from scoria deposits document eruptions about 2000-1900 years ago. Yanshan cone is about 362 m high, and the crater of Gaoshan is 140 m deep.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
