Resumen:
This work presents a high-resolution paleomagnetic and rock magnetic study of two cores collected at Laguna Carmen (Tierra del Fuego, Patagonia, Argentina). Palaeomagnetic and rock magnetic data show that the sample sequence is magnetically homogeneous. Rock magnetic data analysis suggests that the remanence signal is carried by titano(magnetite) grains in stable pseudo single domain (PSD) state. The sequence is characterised by well-defined paleomagnetic properties and can be used to reconstruct a continuous stratigraphic record that provides high-resolution paleosecular variation curves (PSV) for the period 1000-4200 years. The constructed PSV curves are in very good agreement with the available records of Southern Argentina, implying very promising results in the construction of curve patterns for the region.
