Archaeomagnetic Dating

Clip: Season 1 | 2m 58s

Dr. Eric Blinman, director of the New Mexico Office of Archaeological Studies, explains how archaeomagnetic dating can help archaeologists determine the age of their site. When dirt is superheated, magnetic minerals in the soil realign to match the positions of the Earth’s poles. This technique reads that magnetic signature, and then scientists can match it to a plot of where the poles have been.
