Archeomagnetism in the use of brick dating lanos

From the significantly improved dataset a new archaeomagnetic dating curve for the UK is derived through the development of a temporally continuous geomagnetic field model, and is compared with previous UK archaeomagnetic dating curves and global field models.

The new model, ARCH-UK.1 allows model predictions for any location in the UK with associated uncertainties.

Date estimates are presented in the same way as those that arise from radiocarbon dating.

In order to illustrate the model and the inference method used, we will present results based on French, Bulgarian and Austrian datasets recently published.

Archaeological evidence including potsherds, coins and fragments of glass vessels suggests that the workshop was in use from shortly before 400 CE to the first third of the 5th century CE, though from archaeological point of view the period of operation cannot have covered more than a few years.

The modelling we propose allows all these observations and errors to be linked together thanks to appropriate prior probability densities.The errors that occur at different stages of the archaeomagnetic calibration process are combined using a Bayesian hierarchical modelling.The archaeomagnetic data obtained from archaeological structures such as hearths, kilns or sets of bricks and tiles, exhibit considerable experimental errors and are generally more or less well dated by archaeological context, history or chronometric methods (14C, TL, dendrochronology, etc.).castle in Antibes belonged originally to a vast monumental edifice of an unknown origin.No historical records that would allow establishing precise chronological framework of this building exist.Nevertheless, thanks to the mutual comparison of dating results, a reliable chronology have been established.
