obsidian sources

Obsidian sources refer to specific locations where natural volcanic glass, called obsidian, can be found. These sources are identified through geological analysis and sometimes archaeological studies, which trace the unique characteristics of obsidian artifacts back to their original volcanic origin. Knowing these sources helps researchers understand ancient trade routes and cultural interactions, as obsidian was highly valued for making sharp tools and weapons. Identifying obsidian sources involves examining mineral composition, color, and other properties to match artifacts to particular volcanic regions.
