摘要: Abstract Thellier-type determinations of the ancient geomagnetic intensity are reported for a large number samples from Greece, comprising pottery and other archaeologically dated forms baked clay. Comparison is made with results parts world about same latitude: Near East, China western U.S.A. These data indicate that, in time-range studied, variation dipole moment unlikely to have been dominant influence; it suggested that westward drift non-dipole disturbance could responsible.
