Paleomagnetic dating archaeology

Paleomagnetic Project Areas Select a project area from 12 regional maps to learn more about Applied Paleomagnetics projects around the world.Paleomagnetic Projects in Alaska and Northwest Territories, Canada In Alaska, we paleomagnetically oriented cores from North Slope oil fields (Prudhoe Bay, NPRA, ANWR), from the Beringian margin (St.Archaeomagnetic dating is the study and interpretation of the signatures of the Earth's magnetic field at past times recorded in archaeological materials.These paleomagnetic signatures are fixed when ferromagnetic materials such as magnetite cool below the Curie point, freezing the magnetic moment of the material in the direction of the local magnetic field at that time.The stronger component known as the Earth’s poles, reverses direction at irregular intervals.


In conjunction with techniques such as radiometric dating, the technique can be used to construct and calibrate the geomagnetic polarity time scale.

Magnetostratigraphy Magnetostratigraphy, or magnetic stratigraphy, allows age-dating of sedimentary and volcanic strata in which the primary magnetization records distinctive geomagnetic polarity reversals, like the magnetic stripes on the seafloor.
