Abstract
IT is well known that igneous rocks and ceramic objects are permanently magnetized in the direction of the Earth's magnetic field in which they were cooled from a high temperature. I have already pointed out that the baked earth in the hearths of prehistoric dwelling pits would be magnetized similarly, and that this could be applied to developing chronology for anthropology and archæology1. The term ‘geomagnetochronology’ may be defined as chronology from palæomagnetism.
