“…Archaeomagnetic reference curves vary in the method of their construction and presentation. Directional data may be shown as individual time series (e.g., Watanabe, 1958;Kovacheva, 1980), VGPs (e.g., Sternberg and McGuire, 1991;LaBelle and Eighmy, 1997;Lengyel, 2010), or as Bauer plots (Bauer, 1896), where inclination is plotted against declination (e.g., Thellier, 1981;Clark et al, 1988;Gallet et al, 2002;Hagstrum and Blinman, 2010).…”

The aperiodic nature of geomagnetic field variations, both in intensity and direction, can aid in dating archaeological artefacts, volcanic rocks, and sediment records that carry a palaeomagnetic signal. The success of palaeomagnetic dating relies upon our knowledge of past field variations at specific locations. Regional archaeo-and palaeomagnetic reference curves and predictions from global geomagnetic field models provide our best description of field variations through the Holocene. State-of-the-art palaeomagnetic laboratory practices and accurate independent age controls are prerequisites for deriving reliable reference curves and models from archaeological, volcanic, and sedimentary palaeomagnetic data. In this review paper we give an overview of these prerequisites and the available reference curves and models, discuss techniques for palaeomagnetic dating, and outline its limitations. In particular, palaeomagnetic dating on its own cannot give unique results, but rather serves to refine or confirm ages obtained by other methods. Owing

“…Manzanilla's (Beramendi-Orosco et al 2009) date for the great burning is based largely on a few archaeomagnetic specimens. However, the chronology of shifts in the virtual geomagnetic pole (VGP) is itself based largely on calibrated radiocarbon dates (Wolfman 1990) and continues to have some problems (Hagstrum and Blinman 2010; Lengyel 2010)—in addition to issues about individual specimens. I have more confidence in Bayesian analysis of calibrated radiocarbon dates constrained by stratigraphic evidence, as used by Beramendi-Orosco et al (2009).…”

After a century or so of slow decline, major civic-ceremonial structures in the city of Teotihuacan were burned and desecrated, probably around a.d. 600/650, at least some residential structures were abandoned, and the Teotihuacan state collapsed. Few features of Teotihuacan material culture survive in the Basin of Mexico in the ensuing Epiclassic period, which lasted from approximately a.d. 600/650-800/850. Ceramic and other lines of evidence suggest a sizable in-migration of peoples from western Mexico. These newcomers may have arrived in time to add to internal stresses responsible for bringing about Teotihuacan's collapse, arrived later to take advantage of that collapse, or both. Whatever the case, interactions with Teotihuacan survivors were complex and still poorly understood. Descendants of Teotihuacanos probably soon adopted new cultural identities, making them untraceable in the archaeological record, except possibly by biological markers.

“…The chronological data for the Eighmy data set was accessed from the Colorado State University Archaeometric Lab Technical Series (CSU Technical Series) (Eighmy et al., 1987; Eighmy & McGuire, 1989; Eighmy & Klein, 1988, 1990; LaBelle & Eighmy, 1995; Premo & Eighmy, 1997). These volumes include the age for each sampled archeological feature that Eighmy, Lengyel, Sternberg, and associates used in their regional paleosecular VGP models (e.g., Eighmy, 1991; LaBelle & Eighmy, 1997; Lengyel & Eighmy, 2002; Lengyel, 2010), but do not always cite the archeological report that qualifies those chronologies.…”

Archaeomagnetism applies many of the techniques of paleomagnetism to samples of anthropogenic origin. The materials most often studied are those heated by past peoples (hearths, burned floors, pottery, etc.) because the heating and subsequent cooling of the material generally preserve a stable and measurable magnetization. These heated anthropogenic materials hold tremendous potential for contributing to the understanding of variations in Earth's magnetic field over the last several thousand years because
