This paper presents the analysis of chert and orthoquartzite cores recovered from quarry-workshop sites located in the northwestern sector of Tandilia, Buenos Aires province. The main objective is to determine the knapping methods used to reduce the cores and to identify the types of débitage used on each rock. Considering the volumes and morphologies of the cores that were being reduced, the selected technical criteria and production objectives are analyzed. In this sense, different objectives related to obtaining supports represented by modules of different dimensions and thicknesses were identified. In turn, natural and prepared platforms were observed, as well as pieces with unidirectional, bidirectional and multidirectional extractions. There is great variability in the reduction of the cores, some of which are scarcely used and others exhausted, including bipolar pieces. These studies allowed us to recognize different ways in the exploitation of both rocks that are mainly related to the way in which they occur naturally in the outcrops.
