“…The first directional SVC for Greece have been constructed by DeMarco (2007), while for the intensity the first attempt was made by Spatharas (2005). A new, improved version was published by DeMarco et al, 2008. In order to date archaeomagnetically our results, the obtained data for the studied areas (Table 2) have been recalculated to the geographical coordinates of Athens, where the Greek SVC also referred to as a reference site. The relocation was made by using the virtual geomagnetic pole (VGP) method proposed by Noel and Batt (1990).…”

“…Since this value is used by DeMarco et al, (2008) for the elaboration of the new intensity SV for Greece we did not use the Greek curves for dating this site in order to avoid any circular reasoning. Instead, the regional archaeomagnetic model for Europe for the last 3000yrs, SCHA.DIF.3K proposed by Pavon-Carrasco et al, (2009) was used.…”

“…Intensity data reported since 1980 (Liritzis and Thomas 1980) are by far more numerous (for a thorough review see DeMarco et.al., 2008) whereas directional data appeared in 1984 (Downey and Tarling, 1984). Recently new archaeomagnetic data have been obtained following severe selection criteria (Evans & Kondopoulou, 1998, Kovacheva et al, 2000, Kondopoulou & Spatharas, 2002, Tarling et al, 2004, Evans 2006) which leaded to the construction of new intensity (Spatharas, 2005, DeMarco et al, 2008 and directional SVC for Greece (DeMarco, 2007).…”

“…This issue will be further developed as follows. Table 5 provides a compilation of archaeomagnetic data from a broad timespan, ranging from Late Classical-Hellenistic to Early Roman kilns, some of which have already been incorporated in the Greek secular variation curves (De Marco et al 2008bTema et al 2012). We have selected a broader period than the one studied here (Hellenistic-Early Roman) in order to cover potential chronological overlappings and document eventual differentiations following the archaeomagnetic dating, as the archaeological date range is often very broad.…”

“…The scope of this research was to provide accurate data for a robust secular variation curve (De Marco et al 2008bTema et al 2012) and to date archaeological features where possible-that is, where the geomagnetic field variations versus time had already been determined.…”

The present article comprises a multidisciplinary archaeometric approach for the study of Hellenistic and Early Roman kilns in Greece. A collection of previously published and new archaeomagnetic data are combined with new results from mineralogical analytical experiments. The sampled material came from four areas, covering different geological contexts: Katerini, Olympiada, and Polymylos in mainland Greece, and the island of Paros. Extensive rock-magnetic experiments, including identification of the dominant ferromagnetic minerals present, their domain state, and mineralogical alterations during laboratory treatments, have been carried out in order to examine the magnetic properties of the studied materials and prove their suitability for reliable archaeomagnetic determinations. Magnetic cleaning provided well-defined archaeomagnetic directions, and archaeointensity measurements were carried out using both the Thellier-Thellier and Triaxe protocols. Information from both magnetic and mineralogical properties referring to firing conditions is further discussed along with archaeological information. Finally, a new dating of the four sites together with other structures of similar age was carried out using the Pavón-Carrasco model.

One of the main challenges of paleomagnetic research is to obtain high-resolution geomagnetic field intensity reconstructions. For the last millennia, these reconstructions are mostly based on archeomagnetic data. However, the quality of the intensity data available in the databases is very variable, and the high scatter observed in the records clearly suggests that some of them might not be reliable. In this work we investigate how the geomagnetic field intensity reconstructions and, hence, our present knowledge of the geomagnetic field in the past, are affected by the quality of the data selected for modeling the Earth's magnetic field. For this purpose we rank the European archeointensity data in four quality categories following widely accepted paleomagnetic criteria based on the methodology used during the laboratory treatment of the samples and on the number of specimens retained to calculate the mean intensities. Four geomagnetic field regional models have been implemented by applying the revised spherical cap harmonic analysis to these four groups of input data. Geomagnetic field models strongly depend on the used data set. The model built using all the available data (without any preselection) appears to be the less accurate, indicating some internal inconsistencies of the data set. In addition, some features of this model are clearly dominated by the less reliable archeointensity data, suggesting that such features might not reflect real variations of the past geomagnetic field. On the contrary, the regional model built on selected high-quality intensity data shows a very consistent intensity pattern at the European scale, confirming that the main intensity changes observed in Europe in the recent history of the geomagnetic field occurred at the continental scale.
