Abstract

We report new palaeomagnetic, paleointensity and rock-magnetic results obtained in a sequence of 11nephelinitic lavas from the island of São Vicente (Cape Verde). Rock magnetism experiments yielded asingle thermomagnetic curve type, showing good reversibility and displaying low Ti-titanomagnetiteCurie temperatures. Hysteresis parameters show pseudo-single domain structure. Palaeomagnetic analysesindicate that a single paleomagnetic component can be distinguished in 10 of 11 flows, while only in onesite a second larger viscous component is recognized. A normal polarity characteristic component could beisolated in all flows. Paleointensity experiments are still ongoing.
