What are Obsidians?

Obsidians are a type of natural glass that forms when volcanic lava cools rapidly. Unlike other rocks, which have a crystalline structure, obsidians are amorphous, giving them a glassy appearance. These stones are typically black or dark gray, but they can also exhibit a variety of colors and patterns depending on their mineral content and the conditions in which they formed.

How are Obsidians Formed?

The formation of obsidians begins deep within the Earth, where intense heat and pressure cause rocks to melt into lava. When this molten rock erupts from a volcano, it cools quickly upon contact with the air or water, solidifying into glassy obsidian. This rapid cooling prevents the formation of crystals, resulting in the smooth, uniform texture that obsidians are known for.

Why are Obsidians Significant in Eugene, Oregon?
