Magnetic properties and soil micromorphology in the archaeological site Marazzi 2, Isla Grande de Tierra del Fuego, Chile
The aim of the present work is to get an insight into the origin of the magnetic signature (natural and/or anthropogenic) of archaeological deposits and its relation to soil micromorphology. For this purpose, two profiles were sampled from the Late Holocene archaeological site Marazzi 2, located in...
