“…This evolution conforms to the curve previously proposed by Thellier (1981). This is further confirmed by the computation of an average curve using the method developed by Le Goff (1990) and Le Goff et al (2002), which is shown in black-red in Fig. 3 (see results in Additional file 1: Fig.…”

We present a new compilation and analysis of historical geomagnetic measurements made in Western Europe before AD 1750. The dataset in its ensemble provides a coherent evolution of magnetic field directions. Several data points excluded from previous analyses actually appear very consistent with most of the present compilation. A new average historical curve is computed for Paris, which is in very good agreement with the archeomagnetic data obtained in France, while significantly differing from the directional curve expected for Paris before AD 1675 based on the gufm1 model (Jackson et al. in Philos Trans R Soc Lond A 358:957-990, 2000). This finding suggests that the older segment of the gufm1 model lacks reliability and should be improved. Similarly, the historical part of the regional geomagnetic field model built for Europe by Pavón-Carrasco et al. (Geochem Geophys Geosyst 10:Q03013, 2009) should be revised because it erroneously incorporates directions derived from the gufm1 model.

“…7). For the dating purposes, we employed a basic principle of archaeomagnetic dating (Le Goff et al, 2002;Noel and Batt, 1990) that consists in finding the "crossing-point" with the palaeosecular curve of the region. In addition, some stratigraphic restrictions are considered to better constrain the dates.…”

Archaeomagnetic investigation of oriented pre-Columbian lime-plasters from Teotihuacan, Mesoamerica

et al. 2006

Results of an archaeomagnetic study of two excavation field seasons at the Xalla and Teopancazco residential areas of the ancient Prehispanic city of Teotihuacan, Central Mexico are reported. One-hundred and fifty three oriented samples of lime-plasters from the two archaeological sites were collected for the study. NRM directions are reasonably well grouped. Alternating field demagnetization shows single or two-component magnetizations. Rock magnetic measurements point to fine-grained titanomagnetites with pseudo-single domain behaviour. Characteristic site mean directions from both sites are correlated to the available palaeosecular variation curve for Mesoamerica. The mean directions obtained from Xalla site point to average dates of 550 AD±25 years that matches with the documented 'Big Fire' of Teotihuacan (AD 575). Two consecutive construction levels at Teopancazco were estimated as AD 250-350 and AD 350-425 respectively.

“…This distribution depends entirely on the obtained information for dating interval of the studied structures. The last 2000 years are historically well known for the Western Europe and SVCs are obtained for France (Gallet et al, 2002) and Germany (Schnepp and Lanos, 2005). In contrast in South Europe and Asia Minor the prehistoric discoveries are very reach.…”
