 : to measure continental drift? That is ...observe the magnetic alignment
 : of the lava extruded from the midocean rifts....
 
 The symmetric alternation...in magnetic alignment...around the Mid-Atlantic
 Ridge...is a way to detect seafloor spreading...but I don't believe it's
 regular enough...that is periodic enough...to be used as a clock.

sorry...didn't mean to imply regularity...or that it could be used as a
clock...just that it happened ....If there x number of magnetic alignment
variations of sea-floor magma (lava?) then there were x number of magnetic
pole shifts between then and now...and I don't know if there is a way to
determine the interval between pole shifts.
