The Archaeomagnetic Laboratory at the Illinois State Museum has secular variation curves for the southwest, mid-continent and southeast United States. Eric Blinman, director of the New Mexico Office of Archaeological Studies, explains how archaeomagnetic dating can help archaeologists determine the age of their site. Archaeomagnetic dating requires an undisturbed feature that has a high likelihood of containing a remnant magnetic moment from the last time it had passed through the Curie point. Additional data points from archaeomagnetic samples with corresponding dating techniques such as tree ring dating or carbon dates, help refine the regional curves. This involves sufficient mass to take samples from, and a suitable material with adequate magnetite to hold the remnant magnetism.
