The discovered ovens are a rare exampleof very well preserved domed ovens from the Early Neolithic period and are dated basedon archaeological information and radiocarbon dating. Standard thermal demagnetizationprocedures were used to determine the archaeomagnetic direction registered by each ovenduring its last firing and their archaeointensity was determined with the multi-specimenprocedure (MSP-DSC). Both directional and intensity results are of high quality and theyclearly show an intensity low during the Neolithic period. The new results are the firstfull geomagnetic field vector data for this period in Italy. They are compared with othercontemporaneous data from Europe and with global geomagnetic field models. Independentarchaeomagnetic dating of the three ovens has been also performed using the SCHA.DIF.7kmodel. The obtained results are in excellent agreement with the radiocarbon dates andconfirm that all ovens belong to the Neolithic period and were almost contemporaneouslyused. The new results importantly enrich our knowledge of the geomagnetic field during theNeolithic period that is poorly covered by data, not only in Italy but in the whole Europeand show that archaeomagnetic dating can provide very precise results even for prehistoricperiods.∗Intervenantsciencesconf.org:pmag2015:64461
