The magnetic properties of 25 oriented samples of the Permian porphyries\ud from the Lugano district are investigated. After a.c. demagnetization (up to\ud 900 Oe peak value) eleven samples produce a characteristic direction of\ud magnetization, declination (D) = N 143.5OE, inclination (I) = -17O. The other\ud samples show streaking towards the direction of the present-day geomagnetic\ud field; their recent magnetic components are very hard and could not\ud be removed by our a.c. demagnetization procedures.\ud The paleomagnetic pole derived from the Lugano rocks is situated at\ud 41.5?N 119.5OW, and is equally divergent from the other Permian poles from\ud extra-Alpine European rocks as are the ones traced in other parts of the\ud Alps. This divergency is best explained by assuming large-scale tectonic\ud displacement
