Extension lectures

The COLS extension lectures offer research from a broad range of topics to everyday citizens.

The Meiji University Center for Obsidian and Lithic Studies (COLS) has been a research facility affiliated with the Organization of the Strategic Coordination of Research and Intellectual Properties since April 2010. Prehistoric people used obsidian as a lithic raw material throughout the Stone Age, from as early as 38,000 years ago, at the beginning of the Upper Paleolithic period. The COLS has carried out a research project to construct a history of relationships between prehistoric humans and the natural resources that surrounded them, which is connected with the dynamics of paleoenvironmental changes. The COLS extension lectures offer research from a broad range of topics to everyday citizens.
