A Rare Maar Volcanic Group Was Discovered in Inner Mongolia!

A Maar volcanic group - a broad, low-relief volcanic crater caused by a phreatomagmatic eruption - has been found in northern China's Inner Mongolia Autonomous Region, consisting of 116 volcanos, each with a crater diameter of more than 50 meters.

The volcanic group in the northern part of Zhuozi County, Inner Mongolia, has more than 100 craters within a radius of 180 square km, mostly between 100 to 400 meters in diameter.

Unlike common conical craters above the ground, Maar volcanos are a group of broad and shallow craters in shape like a "plate with wide sides and flat bottoms," making them difficult to identify.

Ding said its formation of the volcanic group dates back between 33 million years and 9.4 million years ago.
