Archaeomagnetic dates derived from geomagnetic field direction records in baked materials are proposed for a mediaeval brick kiln (from inclination I and declination D) bricks wall only) northern Belgium. They used to verify whether chronology based on the format of is feasible Flanders. The yielded highly reliable average magnetization corresponding an archaeomagnetic date around A.D. 1650, using British French secular variation curves as reference, at least half century younger than expected historical data. fidelity was controlled by measuring magnetic anisotropy bricks. Anisotropy susceptibility (AMS) measurements demonstrate that have shape related fabric, which induced during molding process. A test control AMS can substitute thermo-remanent (ATRM) failed because changes laboratory heating. © 2003 Wiley Periodicals, Inc.
