The samples are sent to an Archaeomagnetic Laboratory for processing. Within these weaker areas the local directions and intensities change gradually secular variation. Adrien Hannus describes Folsom people's hunting strategy and the innovation of the Atlatl. Each of the samples is measured in a spinner magnetometer to determine the thermal remanent magnetism of each sample. Concepts Deep time Geological history of Earth Geological time units.

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.
