AB A paleointensity study has been carried out on samples from 13 volcanic sites belonging to four differenttypes of volcanism of late Miocene to Pliocene age from south-eastern Spain. Rock-magnetic experimentsincluding measurement of thermomagnetic curves and hysteresis parameters as well as ore microscopyshowed that the main carriers of remanence were low-Ti titanomagnetite and titanohematite. A PSDdomain structure was observed in most samples. 43 of 90 samples from only 7 sites provided successfulpaleointensity determinations. 4 sites yield very low paleointensity values, but only in sites M4 and G15anomalous paleomagnetic directions confirm an intermediate polarity. Lamproitic and calc-alkaline volcanicsproved to be more suitable for paleointensity determinations in this area
