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