Using archaeomagnetism to improve the dating of three sites in Catalonia (NE Spain)

Abstract

19Archaeomagnetic dating for four archaeological structures has been attempted in 20 Catalonia (NE Spain) using magnetic inclination and declination values from three 21 reference curves: the Iberian SVC and two curves computed using the regional 22

Refining Holocene geochronologies using palaeomagnetic records

“…(2013) gave two potential time intervals and hence larger uncertainty than the TL dating. A more conclusive application of the method was using full vector magnetic results from two kilns in Greece (Tema et al, 2015 -Chakrouni et al, 2013;Casas et al, 2018) or burnt cave sediments from the Bronze age in Spain (Carrancho et al, 2017).…”

“…Archaeomagnetic dating is wellestablished in Europe (Hervé, Chauvin, Lanos 2013;Batt et al 2017) and regularly utilised for dating fired archaeological structures, i.e. furnaces, kilns or hearths (Aidona et al 2018;Casas et al 2018). Palaeosecular variation curves (PSVC) mainly cover country-specific areas and facilitate archaeomagnetic dating for those countries where there is enough data.…”

Estudios arqueomagnéticos y de arqueointensidad en materiales arqueológicos quemados de la Península Ibérica y el Cáucaso

“…The archaeomagnetic dating technique, is based on the knowledge of the directional and/or intensity variations of the Earth's magnetic field (EMF) with time, and it is a valuable tool increasingly used to date archaeological combustion structures for the last millennia (e.g. : Ruiz-Martínez et al, 2008;Casas et al, 2018;. In addition, information about temporal variations of the EMF is necessary to understand and model the characteristics of the field.…”

“…: kilns, potteries, bricks, etc) to register the direction and/or the intensity of the EMF when, after being heated above its Curie temperature, the archaeological material cools down in the presence of the EMF to room temperature, acquiring a thermal remanent magnetization (TRM). One of the advantages of archaeomagnetic dating (e.g., Casas et al, 2018) on materials carrying a TRM signal is that this technique dates the precise time of the last heating to which the analysed material has been subjected. The last heating of an archaeological combustion structure is usually associated with the end of its use or the abandonment of the site (e.g., Casas et al, 2018).…”

The last heating of an archaeological combustion structure is usually associated with the end of its use or the abandonment of the site (e.g., Casas et al, 2018). By comparing the mean direction and archaeointensity values of the samples with a geomagnetic field model or an available regional secular variation curve the age of the magnetization (its last use) can be determined.…”
