Arxan-Chaihe

화산대지 · China · 1677m

The Arxan-Chaihe volcanic field covers around 2,000 km2 with at least 47 identified vents, some of which can be seen in a NE-SW trend through the center of this September 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 69 km across). As well as eruptions producing spatter cones and lava flows, there are phreatomagmatic vents and fissure-controlled vents.

지질학적 요약

The Arxan-Chaihe Volcanic Field, in the central Da Hinggan Mountains of Inner Mongolia in NE China, contains at least 27 volcanic features. The youngest cones, including Yanshan and Gaoshan, 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 2,000-1,900 years ago. The area has been designated as a National Geopark.
