Paleomagnetic dating accuracy

In this article we shall discuss how we can use the paleomagnetism in rocks to attach dates to them (paleomagnetic dating).

One we have dated a sufficient number of rocks and measured the orientation of the magnetism they contain, we can build up a picture of how the position or apparent position of the poles over time.

So if we are then faced with a rock the date of which we do not know, then we do know (of course) the latitude and longitude at which we found it, and we can measure the orientation of its magnetism, and so we can look at the global picture we've built up of continental drift, and so figure out when the rock must have formed in order to have its magnetism oriented in just that direction.

ARCHEO is a new archeomagnetic directional database compiled by Don Tarling at the University of Southampton, U. The PMAG programs are designed to operate in a UNIX (or LINUX) environment. and published by the University of California Press (2009).

Details of PSVRL are given in Mc Elhinny and Mc Fadden (1997).

Perrin, Schnepp and Shcherbakov (1998) give a brief description of PINT and Mc Elhinny, Opdyke and Pisarevsky (1998) give a description of MAGST. Lisa Tauxe, offers an on-line version of companion software to the book Paleomagnetic Principles and Practice.

You may therefore be wondering why, if we have perfectly good dating methods already, we don't just use them.

However, the advantage of paleomagnetic dating is that we can use it on different rocks from those susceptible to our ordinary methods of absolute dating: while most radiometric methods usually require igneous rocks, paleomagnetism can be measured in sedimentary rocks.

All other databases are complete up to December 1999 and in some cases include data from early in 2000.
