Geomagnetic intensity in Egypt and western Asia during the second millennium BC

摘要: We report here detailed evidence that during the period 1600–1100 BC geomagnetic intensity in Egypt and western Asia increased monotonically by a factor of 1.6 propose that, within this region period, such can be used as dating tool. The results, which form reference data for age evaluation, are from well-dated archaeological samples baked clay Cyprus, Egypt, Israel Mesopotamia using version Thellier technique1 modified use cryogenic (SQUID) magnetometer2. There is no more rapid fluctuations have been reported Egypt3, Greece4 France5 other periods. Earlier than 1700 remains close to present-day level, although there some indication small fluctuation.
