El Complejo Minero prehispánico San José del Abra: Arqueobotánica y redes de abastecimiento de una mina incaica en el Collasuyu

This article presents the results of archaeobotanical research carried out in the San José del Abra mining district in northern Chile. This mine, after initially being exploited during the Late Intermediate period, was later incorporated into Tawantinsuyu, leading to a reorganization and intensification of mining production. The excavations carried out at the Inkawasi-Abra camp recovered a wide diversity of plant remains from different ecosystems and ecological zones of the region, which played essential roles within the living space. On the one hand, they provided the Atacameño mitayos with food, fuel, and raw materials. On the other hand, they were part of communal ceremonial and food preparation contexts related to political commensalism, reciprocal relationships, andmining rituals.Most of the analyzed plants come from the Atacameño streams and oases, including agricultural products, chañar (Geoffroea decorticans), and carob tree (Prosopis sp.), as well as wild and cultivated plants from puneño environments, low valleys, and the Pacific coast. These results allow us to map relationships and supply networks for the mine during the Inca period, as well as contributing to our knowledge of the miners who carried out the production in San José del Abra.
