AN ARCHAEOMAGNETIC STUDY OF A ROMAN BATH IN SOUTHERN FRANCE

摘要

Absolute Thellier-Thellier archaeointensity determinations were conducted on 137 tiles and sedimentary blocks from five different structures from the 'Site de la Molsre', southern France, to constrain the archaeological interpretation of a relative age difference between structures and add new data to the French secular variation database. We present 89 new archaeointensity and 20 new directional results, with averages of 57 (+8) mu T in the second century AD and 68 (+/- 7) mu T in the third century AD. The overall data trend is consistent with the limited available data, indicating rapidly increasing field intensity from the second to the third century AD.
