Abstract The obsidian in Changbaishan area is the result of volcanic activities. It is formed by the specific eruption of the Changbaishan volcano, with special geological characteristics. The obsidian is also the evidence for the history and culture of Changbaishan Mountain. Based on analysis of chemical composition and tests of physical properties, this paper preliminarily studies the characteristics, formation, distribution and genesis of the obsidian from Changbaishan Mountain, which would provide a reference for the development and utilization of the obsidian in the area.
