“…For dating purposes, we choose the time interval between 1000 BCE and 500 CE, based on the available age of the pottery style and radiocarbon dates. Both available local paleosecular reference curves (Mahgoub et al, 2019; García-Ruiz et al, 2022) show the paucity of directional data obtained from well-dated burned archaeological artifacts between 1000 BCE and 500 CE. The recent global geomagnetic models SHAWQ2K and SHAWQ-Iron Age (Campuzano et al, 2019; Osete et al, 2020) are of different age intervals.…”

A detailed magnetic mineralogy and archaeomagnetic study was carried out on recently discovered domestic hearths and burned floors at the Chak Pet archaeological settlement (Tamaulipas, Mexico). The study aimed to obtain reliable absolute chronological constraints on the early development of Huastecs during the Formative period. Oriented hand samples corresponded to four domestic hearths and one burned floor. Continuous thermomagnetic curves revealed mostly irreversible behavior, while titanomagnetites, titanomaghemites, and goethites are assumed to carry the remanent magnetization. In total, 87 specimens were subjected to stepwise demagnetization of natural remanent magnetization using an alternating field procedure. Characteristic remanent magnetization directions were obtained for 29 samples of two hearths and one burned floor. No single, technically acceptable paleointensity determination was obtained. The new archaeomagnetic age intervals for Chak Pet allow locating the origin of this settlement at the Gulf of Mexico within the Middle Formative (900–600 BCE) continuing until the Late Formative period (350–100 BCE). New archaeomagnetic ages are in accordance with the diagnostic pottery analysis. Dated archaeological elements are associated with both ceramic types and different sets of burials, providing a reliable tool to calibrate their chronological and stratigraphic positions.

“…Among these materials, archaeological artifacts are nearly optimal recorders of the ancient field due to their wide abundance, suitable magnetic properties (Brown et al, 2021), and our ability to date them precisely. Archaeomagnetic intensity (archaeointensity) data published in the past few decades have enabled the construction of regional geomagnetic intensity variation curves (Bonilla-Alba et al, 2021;Cai et al, 2017;Garcia-Ruiz et al, 2022;Genevey et al, 2016Genevey et al, , 2020Genevey et al, , 2021Goguitchaichvili et al, 2023;Herve et al, 2019;Kovacheva et al, 2014;Osete et al, 2020;Rivero-Montero et al, 2021;Schnepp et al, 2020;Tema & Lanos, 2021) and the development of global geomagnetic models (Arneitz et al, 2019;Campuzano et al, 2019;Constable et al, 2016;Korte et al, 2019;Nilsson et al, 2022;Pavon-Carrasco et al, 2014;Schanner et al, 2022) which have significantly improved our understanding of the temporal evolution of the global field and the nature of flow patterns in the outer core. With the understanding that the rate of change in field intensity can exceed 10 μT per century (Gallet et al, 2020(Gallet et al, , 2021Genevey et al, 2021;Kostadinova-Avramova et al, 2021;Osete et al, 2020;Rivero-Montero et al, 2021;Shaar et al, 2011Shaar et al, , 2022, it became clear that the temporal resolution of archaeointensity datasets should be at least one data point per century.…”

The rich and extensively studied archaeological record of the Near East provides an opportunity to develop a comprehensive archaeomagnetic dataset for exploring the behavior of the geomagnetic field with high precision. The Levantine archaeomagnetic curve (LAC) project is an ongoing effort to develop a continuous high‐resolution geomagnetic intensity curve for the Levant and Mesopotamia. The first version of the LAC covered the period between 3000 and 550 BCE. Here, we report archaeointensity data from 169 samples compiled into 32 groups dating between the 7th and the 1st centuries BCE aiming at extending the LAC up to the end of the first millennium BCE. Twenty‐two groups are assembled from storage jar handles bearing different types of royal seal impressions, which were used in Judah as part of a taxation administrative system. These groups are combined with 10 other groups of pottery assemblages, three of which are from Hellenistic destruction layers dated using radiocarbon and coins. The new curve shows that the Levantine Iron Age Anomaly (LIAA) spanned 550 years (1100 ‐ 550 BCE) and that the rate of decline during the last spike around 600 BCE could have reached ∼0.6 μT/year. During the 6th century, the virtual axial dipole moment (VADM) dropped from 160 ZAm2 to 125 ZAm2 after which field intensity only slightly increased to 135 ZAm2, until another considerable decline to ∼90 ZAm2 during the 3rd to the 1st centuries BCE. We highlight the archaeomagnetic implication of the new curve in inferring the relative chronological relationship between different stamp types.
