Objective: To establish the relationship between sedimentary contribution,wind morphologies and processes of formation of the archaeological recordon the north coast of the San Matías Gulf (Río Negro).For this purpose, theapplied methodology consisted of an exhaustive review of the geological,geomorphological and geoarchaeological literature, as well as field visits, inwhich sedimentary samples were collected from several geomorphologicalunits for subsequent granulometric analyzes. The results obtained showthat coastal environments, in response to this dynamism, on the one handfacilitated the formation of different types of morphologies, such as dunesand, on the other hand, both coastal dynamics and anthropic activityhave affected qualitative and quantitative properties of the evidence.Conclusion: due to the environmental conditions of the region studied,the archaeological material is continually being exposed, redeposited anddisplaced by wind action, thus affecting the primary deposition context.
