Abstract: Presentamos la caracterización de la tecnología lítica de un sitio bajo abrigo rocoso emplazado en un sector de poco acceso y visibilidad dentro del cordón Chapelco, Neuquén, Argentina. El sitio se distingue por el uso de obsidianas procedentes de al menos tres fuentes, dos disponibles a menos de 25 km y otra distante 150 km al norte. Los artefactos están relacionados con la conformación y/o mantenimiento de instrumentos bifaciales que aparecieron manufacturados en el sitio. Entre estos instrumentos predominan pequeñas lascas o microlitos de obsidiana con rastros de uso, que postulamos como producto del mantenimiento de utensilios expeditivos enmangados. Finalmente, en base a su cronología y contextos arqueológicos asociados cercanamente, se sostiene que el sitio y las actividades desarrolladas en el mismo son parte de estrategias vinculadas a la temprana resistencia y enfrentamiento con conquistadores hispanos. ; Techno-Typological and Geochemical Analysis of Lithic Artifacts (Microliths) from Alero Doña Mica, a Camp inside the Northern Patagonian Forest of Argentina during the Spanish-Indian Contact. We present the characterization of the lithic technology of a site under a rock shelter located in an area of poor access and visibility within the Chapelco range, Neuquén, Argentina. The site is distinguished by the use of obsidian from at least three sources, two available within 25 km and another one 150 km to the north. The artifacts are related to the shaping and/or maintenance of bifacial tools that appeared manufactured at the site. Among these instruments, small obsidian flakes or microliths with traces of use predominate, which we postulate as a product of the maintenance of expeditious tools with sleeves. Finally, based on its chronology and closely associated archaeological contexts, it is argued that the site and the activities carried out there are part of strategies linked to early resistance and confrontation with Hispanic conquerors.
