Large geomagnetic field anomalies revealed in Bronze to Iron Age archeomagnetic data from Tel Megiddo and Tel Hazor, Israel

“…The "spikes" are the extreme climax of a high field maximum (>160 ZAm 2 ) in the Levant that appears in close approximation to other unusually high paleointensity values seen in Turkey (Ertepinar et al, 2012) and Georgia (Shaar et al., 2013), and to other local maxima with lower values seen, for example, in France (Herve et al, 2013), and SE Asia (Hong et al, 2013). Thus, at least at a continental scale, the high-field episode is likely associated with a complicated field structure Kovacheva et al, 2009;Tema and Kondopoulou, 2011;Tema et al, 2012;Kovacheva et al, 2014), suggesting a complex global deviation from a simple dipole configuration (de Groot et al, 2013(de Groot et al, , 2015 that calls for further investigation.…”

Is it possible to identify temporal differences among combustion features in Middle Palaeolithic palimpsests? The archaeomagnetic evidence: A case study from level O at the Abric Romaní rock-shelter (Capellades, Spain)

“…In Europe for example, most SVCs "only" cover the last 2-3 millennia (e.g. Gallet et al 2002;Schnepp and Lanos 2005;Gómez-Paccard et al 2006;Tema et al 2006;Zananiri et al 2007) and exceptionally some records reach the last 8 ky (Kovacheva et al 2014;Kondopoulou 2011, Carrancho et al 2013). …”

Investigating the archaeointensity determination success of prehistoric ceramics through a multidisciplinary approach: new and re-evaluated data from Greek collections

“…The recently published Bulgarian Bayesian curve is also plotted in Fig. 11 (Kovacheva et al 2014). Finally, we also plotted the results computed using three geomagnetic field models: the SHA.DIF.14k (Pavón-Carrasco et al 2014b), the PFM9k.1 (Nilsson et al 2014) and the CALS10K.10b (Korte et al 2011).…”

“…The new archaeointensity for APK (1364 ± 99) fits very well with the high-quality intensity previously Figure 11. The new intensity results (in orange) are compared with previous high-quality archaeointensity data from Greece (in green) and with the Bulgarian Bayesian curve (Kovacheva et al 2014) relocated to Thessaloniki coordinates. The other Greek data, which do not accomplish modern quality criteria are plotted in grey (see text for further details on the criteria used to perform the selection).…”

“…Balkan archaeomagnetic studies started in the late 1960s with the work of Mary Kovacheva (Kovacheva 1969). Since then, a considerable amount of both directional and intensity data have been added (see Kovacheva et al 2014 for a recent compilation). In Greece, systematic archaeomagnetic investigations started about 10 yr later (see Tema & Kondopoulou 2011and De Marco et al 2008 for a review), although the first data were published before, by Belshé et al (1963).…”
