Magnetic Alteration of Soils by Late Holocene Hunter–Gatherer Groups (Tierra Del Fuego, South America)
(Wiley, 2017-01)
The present work aims to analyse the magnetic signature from the Late Holocene open-air archaeological deposits of hunter–gatherer ephemeral occupations. For this purpose, two profiles were sampled at the Marazzi 2 site ...
