1984) could in principle reflect not only the geomagnetic secular variation, but also the disturbing effect of older lava flows.
In this interval, the geomagnetic secular variation pattern in the Canary Islands as revealed by the PSVC is generally coherent with the results obtained from geomagnetic models constructed both from historical/instrumental and archeomagnetic/paleomagnetic observations (GUFM1, ARCH3K.
A final consideration concerning the applicability of this methodology should be made: it is well known that geomagnetic secular variation averages to zero on timescales of ~ 10 ka, implying that similar values of the paleomagnetic elements (i.
