Abstract

A magnetic map of the Ezcurra Inlet area on King George Island and magnetic parameters from some rocks adjacent to it are presented and interpreted. Field measurements were acquired by boat and land surveys. A set of local  distinct magnetic anomalies stretching in the south-eastern coast of Ezcurra Inlet and located on faults transverse to the Ezcurra Fault was defined. At least part of them define location of  volcanic activity centres.  A lineal arrangement of anomalies indicates that the fault or fracture parallel to the Ezcurra Fault in sites crossed by transverse faults opened up magma migration paths. The map of regional magnetic anomalies  similarly to the previous seismic data indicate that the deeply rooted Ezcurra Fault turns in western Ezcurra Inlet to the NW. This non-straight course does not support its strike-slip nature.
