Its geographical location, accessibility, and quality, provide advantageous characteristics of procurement when compared to other known sources of obsidian. However, the geographic dispersion of this source is narrower compared with other Andean obsidian sources. Previous geochemical studies permitted discriminating between two sub-sources called El Peceño-1 and El Peceño-2. Recent field sampling allowed locating outcrops of both sub-sources and of processing and extraction locations. In this paper, spatial and geochemical characterization of the sub-sources, their macroscopic particularities, and first trends of their technological analysis are presented. The results show differences in distribution spatial of the sub-sources and production activities corresponding to different varieties of El Peceño obsidian. Flake and preform production were probably the activities conducted at El Peceño-1, while cortex removal and core formalizing, were the main activities conducted at El Peceño-2. Finally, expectations for the most frequent mode of transportation of these varieties of obsidian and the perspectives for future work are presented. La fuente primaria de obsidiana El Peceño se encuentra ubicada en la planicie oriental del sur de Mendoza y su uso ha sido vinculado a contextos arqueológicos del Holoceno Tardío. Su ubicación geográfica, accesibilidad y calidad para la talla le otorgan características ventajosas en relación con otras fuentes de obsidiana conocidas. Sin embargo, su dispersión geográfica es menor que la registrada en las fuentes de obsidiana de cordillera. Estudios geoquímicos previos hicieron posible discriminar dos sub-fuentes denominadas El Peceño-1 y El Peceño-2. Recientes muestreos de campo permitieron ubicar espacialmente los afloramientos de ambas sub-fuentes y los talleres de procesamiento y extracción. En este trabajo se presenta la caracterización espacial y geoquímica de las sub-fuentes taller, sus particularidades macroscópicas y las primeras tendencias de su abordaje tecnológico. Los resultados muestran diferencias en la distribución espacial de las sub-fuentes y en las actividades de producción representadas en las variedades de El Peceño. La obtención de lascas y la confección de preformas serían actividades representadas en El Peceño-1, mientras que el descortezamiento y formatización de núcleos son frecuentes en El Peceño-2. Por último, se proponen expectativas del modo de transporte de estas variedades de obsidiana y las perspectivas de trabajo futuro. Facultad de Filosofía y Humanidades.
