In the present work, we focus on Marazzi 2 Site, a Late Holocene short-lived-redundant occupation of terrestrial hunter-gatherer from the southeastern coast of Inútil Bay, northwestern steppe of Tierra del Fuego, Chile. Our aim is to understand the geomorphology, stratigraphy, formation processes and pedogenesis in relation to the human occupation for the last ~3000 years. For this porpoise, we integrate geomorphology, soil micromorphology, mineralogical analysis, geochemical data and magnetic

... usceptibility data, as well as the micro-and macro-frequency distribution of the archaeological material. Through all these lines of evidence we discuss three moments in the interplay between geomorphology, soil development and human occupation. First, a very low intensity of human occupation (beginning before 900 BC) was located at the river floodplain which was associated with a lack of or very weak pedogenesis. Second, multiple human occupations related to a shell midden formation on a low river terrace exhibited a weak upper horizon development but abundant coatings indicative of wetter conditions. Third, there was a second peak in human occupation intensity, but with relative less emphasis on marine resource use, which was related to stronger soil development along the present river terrace.
