Abstract
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
