Archaeomagnetism in the Levant and Mesopotamia Reveals the Largest Changes in the Geomagnetic Field. [PDF]

J Geophys Res Solid Earth, 2022
Abstract Our understanding of geomagnetic field intensity prior to the era of direct instrumental measurements relies on paleointensity analysis of rocks and archaeological materials that serve as magnetic recorders. Only in rare cases are absolute paleointensity data sets continuous over millennial timescales, in sub‐centennial resolution, and ...

Archaeomagnetic dating of seven archaeological fireplaces in the Netherlands

Netherlands Journal of Geosciences — Geologie en Mijnbouw, 1997
The palaeomagnetic directions of seven Dutch fireplaces are compared with the archaeological age estimates which range from the first to the 17th century AD. A comparison with the British master curve of secular variation for archaeomagnetic dating results in a refinement of the archaeological age estimates in two cases, while four other archaeological

Using Palaeomagnetic Techniques to Date Indigenous Archaeological Sites in New Zealand

Heritage, 2023
Aotearoa/New Zealand was first settled by the Māori people some 800–1000 years ago. Archaeomagnetism provides one of the few means of dating early sites of Māori occupation, particularly when radiocarbon dating is not feasible.

Depopulation of the Northern Border of Mesoamerica during the Early Postclassic: Evidence from the Reappraisal of Archaeomagnetic Data

Land, 2022
The Mesoamerican Postclassic and Epiclassic were periods of drastic change and transformation related to social, political and economic aspects as well as settlement patterns.

Structure, evolutionary context and chronological data of the Monforte de Moyuela Roman dam (Ebro Basin, NE of Spain)

Geoarchaeology, Volume 38, Issue 4, Page 482-509, July/August 2023., 2023
Abstract The Monforte de Moyuela dam, also known as Ermita de la Virgen del Pilar dam, is a Roman reservoir built on a tributary of the Aguasvivas River (Ebro basin, Spain). A multidisciplinary study has been carried out to investigate this kind of Roman water infrastructure. It is the fifth‐highest dam (16.8 m) in the Iberian Peninsula and the seventh

Late Holocene Paleomagnetic Secular Variation in the Chukchi Sea, Arctic Ocean

Geochemistry, Geophysics, Geosystems, Volume 23, Issue 5, May 2022., 2022
Abstract The geomagnetic field behavior in polar regions remains poorly understood and documented. Although a number of Late Holocene paleomagnetic secular variation (PSV) records exist from marginal settings of the Amerasian Basin in the Arctic Ocean, their age control often relies on a handful of radiocarbon dates to constrain ages over the past 4 ...

On‐site non‐destructive determination of the remanent magnetization of archaeological finds using field magnetometers

Archaeological Prospection, Volume 29, Issue 2, Page 205-227, April/June 2022., 2022
Abstract The determination of the natural remanent magnetization (NRM) of archaeological features can be used for magnetic modelling, joining of shards, archaeomagnetic dating or the investigation of the firing–cooling–collapsing order of ancient buildings.

Global Evolution and Dynamics of the Geomagnetic Field in the 15–70 kyr Period Based on Selected Paleomagnetic Sediment Records

Journal of Geophysical Research: Solid Earth, Volume 126, Issue 12, December 2021., 2021
Abstract Reconstructions of the geomagnetic field on long time scales are important to understand the geodynamo processes in the Earth's core. The geomagnetic field exhibits a range of variations that vary from normal, dipole‐dominated secular variation to geomagnetic excursions and reversals.

Searching for the fundamentals of rehydroxylation dating of archaeological ceramics via NMR and IR microscopy

Journal of the American Ceramic Society, Volume 104, Issue 10, Page 5328-5340, October 2021., 2021
Abstract Determining absolute ages of archaeological ceramics is crucial for understanding past societies and reconstructing their accurate chronologies. The amount of OH hydroxyl chemically combined with ceramic material has been claimed to provide an ‘internal clock’ that can be read via RHX dating to determine the elapsed time since it was fired ...
