  ABSTRACT: We carried out a geomagnetic investigation using Iphone 4S? integrated magnetic sensor. The investigated area is a faulted sedimentary terrain crossed by basaltic volcanic veins. The obtained magnetic anomaly map shows the limits between the sedimentary rocks and a magnetic body at a given depth. These results are compared to the geometry of the magnetic body as shown by geological maps. The results seem to be accurate for the determination of geometry and the depth of the magnetic body.
