Significant use of paleomagnetic data
The most significant use of paleomagnetic data is three-fold: it is a proof of the movement of the tectonic plate; its data can be used to plot and map the movements of the tectonic plates, and thus the movements of the supercontinents as they broke up; and its data shows that the poles have reversed several time over the earth's lifetime. It was an early proof of Wegener's theory of continental drift, moving it into a more accurately described plate techtonic structure. Basically palemagnetism measures the strength and direction of magnetic fields in ferrous metal patterns on the earth's crust showing plate movement, where naturally magnetically induced ferrous crystals align themselves along the N-S plain during the solidifying of the ferrous crystals within the ignious rock as it hardens. The mapping of these directional data of the ferrous crystals set in solidifying magma. the mapping shows where the continental remnant/techtonic plate has been ans where it finally ended up. In combination with comparative fossil analyses and even a compartison of typical living birds, animals, insects, plants and fish the paleomagnetic data gives a crear view of what happened over the billions of years of continental Drift, and as it continues today.

with paleomagnetism, theres always been one thing that has confused me somewhat. I wonder what causes the magnetic field to change, and when it does "flip", is it an immediate thing, or is it a gradual thing. wouldnt this also have some sort of a profound effect on nature aswell. im not sure but dont birds have somthing in them that helps them align with north (magnetic) and thus migrate? would be grateful if anyone could answer these questions :)


 * I don't know about biological effects but the duration of the "flip" is 2 to 10 thousand years (this is an extremely short time with regards to the geological time scale but a long time when it comes to humans). The cause of the "flip" lies in the liquid outer core (the geodynamo process) and is very much debated. --Octupole
