Archaeomagnetic dating was described in the 1992 publication “Paleomagnetism: Magnetic Domains to Geologic Terranes.” By Robert F. 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.Before clay is fired and while lava is still in a molten state, the very weak magnetic fields of individual particles are randomly oriented. Later, its thermoremnant magnetism is measured with a magnetometer.By comparing these data, a researcher can determine the direction of magnetic north at the last time the sample had been exposed to a high temperature.. The earliest evidence of writing anywhere in the world only goes back about 5000 years.
