A survey of the main magnetomineralogical characteristics of 92 archeomagnetic samples from 37 sites in Greece, Italy, North Africa, and China is presented. Coercive force spectra suggest that magnetite and/or titano-magnetite dominates both natural and laboratory remanences (NRM, ARM and IRM). This is confirmed by thermal demagnetization, which establishes the overwhelming role played by these minerals. Magnetic granulometry techniques indicate that no particular domain state predominates. Some samples are dominated by very small particles near the single-domain/superparamagnetic boundary, some by pseudo-single domain particles, and others by what we interpret as mixtures.
