Briefings

Research published in 2026 by Kari Schleher at the University of New Mexico investigates whether archaeologists can identify the specific sources of azurite, a blue copper mineral used by Ancestral Pueblo people since at least 1,400 years ago. The study aims to determine if chemical signatures can distinguish between different mining locations, potentially revolutionizing how ancient sites are interpreted.

Key points

• Kari Schleher, an assistant professor in the University of New Mexico's Department of Anthropology, recently published research examining the ability to determine azurite mineral sources.
• Azurite is a vivid blue copper mineral used by the Ancestral Pueblo people starting at least 1,400 years ago.

Context

This study addresses a critical gap in understanding ancient material sourcing, which is essential for reconstructing trade networks and settlement patterns of the Ancestral Pueblo civilization.

Limitations

The evidence is limited to a single published article from 2026 by Kari Schleher at the University of New Mexico. No additional data, dates, or geographic locations are provided beyond the 1,400-year timeframe for azurite usage.
