They also point toward the location around the geographic north pole where the magnetic north pole was at that moment in its wandering.

This heating, or firing, process resets the iron particles in the clay.

This involves sufficient mass to take samples from, and a suitable material with adequate magnetite to hold the remnant magnetism. In the early to mid s, Dr. The Historic England Archaeomagnetic Dating guidelines are intended to help archaeologists, particularly curators, consultants and project managers to better understand the archaeomagnetic dating technique and thus to make optimal use of it as one of the range of scientific dating methods available for examining archaeological chronology.

This process is called thermoremanent magnetization in the case of lava and clay, and depositional remanent magnetization in the case of lake and ocean sediments.

Archaeomagnetic dating is based on the comparison of directions, intensities or polarities with master records of change.
