Andean Archaeology and pre-Columbian mining and metallurgy
Planned activities for the visit of the Humboldt Fellow, María Florencia Becerra (CONICET), in January 2026
María Florencia Becerra, a researcher at the National Scientific and Technical Research Council (CONICET), Argentina, will visit Bochum in January 2026 as a Humboldt Fellow, offering two lectures and one workshop on Andean Archaeology and pre-Columbian mining and metallurgy.

Green and blue minerals and rocks played significant roles in multiple dimensions of pre-Columbian Andean societies. Their extraction and circulation shaped human–environment interactions in the region since ancient times. Among these minerals, copper held a particularly important place due to its role in metallurgical and mining traditions. Yet, despite its significance, many aspects of its use remain poorly understood—especially which minerals were selected and worked for lapidary purposes.
This presentation synthesizes research carried out to date in the Southern Andes, focusing on several case studies from different sites and contexts in pre-Columbian Northwestern Argentina, particularly during the Late and Inka Periods (10th–16th centuries). Part of this research has been developed in collaboration with the Archaeometallurgy and Materials Science departments of the Deutsches Bergbau-Museum Bochum.
20.01.2026 – 4pm c.t.
Since 2004, GAEPuNo (Archaeology and Ethnohistory Group of the Northern Puna) has been conducting research in the northern highlands of extreme Northwestern Argentina, in Jujuy Province. One of the main lines of research concerns mining and metallurgy during pre-Columbian and Colonial times. This presentation will highlight part of the results of this research, with special emphasis on the most recent outcomes of our investigations.
In addition, it will particularly showcase the collaborative projects developed with local Indigenous communities for the preservation and exhibition of mining heritage in the area. This work is especially relevant in a region where mining heritage is celebrated, yet contemporary mining projects remain highly contested due to their social, economic, and environmental impacts. The debate involves multiple stakeholders—including the state, mining companies, and local communities—who negotiate the meanings and consequences of both past and present extractive activities. The presentation will also address the challenges of collaborative work, as well as the contributions that can be made to tourism promotion, heritage conservation, and community claims, underscoring how collaborative archaeology can contribute to strengthening Indigenous rights and sustainable forms of heritage management.
