摘要：

Paleomagnetic data from a sedimentary section from Santa Lucia archaeological site, Corrientes province (Northeastern Argentina) are reported. Natural remanent magnetization obtained from 74 oriented cores showed normal and intermediate magnetic remanence with negative and positive low inclination values during the Late Holocene. Characteristic remanent magnetization was determined by progressive demagnetization using the AF method. Virtual geomagnetic poles show some agreement with those registered during the terminal Pleistocene and Holocene in other sites from the southern cone of South America. Palaeomagnetic poles for other contemporaneous sites from northeastern Argentina fall some similar to 3-15 degrees away from the Earth's rotation's axis.
