High‐Fidelity Archeointensity Results for the Late Neolithic Period From Central China [PDF]
Geophysical Research Letters, 2020 AbstractArcheomagnetism focuses on exploring high‐resolution variations of the geomagnetic field over hundreds to thousands of years. In this study, we carried out a comprehensive study of chronology, absolute and relative paleointensity on a late Neolithic site in central China. Ages of the samples are constrained to be ~3,500–3,000 BCE, a period when

Archeointensity in Northeast Brazil over the past five centuries
Earth and Planetary Science Letters, 2010 Abstract This study presents the first archeointensity results from Northeast Brazil obtained from 14 groups of architectural brick fragments sampled in the city of Salvador, Bahia State (13°S, 38.5°W) and dated between the middle of the XVIth century and the beginning of the XIXth century.

New archeointensity data from Spain and the geomagnetic dipole moment in western Europe over the past 2000 years [PDF]
Journal of Geophysical Research, 2008 Archeomagnetic studies on 14 kilns, a group of jar fragments, and a collection of baked bricks dated between 1000 and 1959 AD plus one Roman pottery kiln have been conducted in order to obtain high‐quality archeointensity data to enhance the western European database.

Geomagnetic field intensity behavior in South America between 400 AD and 1800 AD: First archeointensity results from Argentina [PDF]
Physics of the Earth and Planetary Interiors, 2011 Abstract An absolute archeointensity study in Northwest Argentina provided 25 independent geomagnetic field lectures supported by 37 radiometric dates between AD 400 and 1800. The mean, cooling rate and remanence anisotropy corrected archeointensity values obtained in this study range from 36.5 ± 2.6 to 63.1 ± 8.7 μT, with corresponding Virtual Axial

Studia Geophysica Et Geodaetica, 2013 We report the results of a rock magnetic and archeointensity study on pottery fragments recovered at the archaeological site of Puertas de Rolón, Capacha culture (Colima), that is considered one of the most important pre-Classic cultural developments of western Mesoamerica, Mexico.

GEOMAGIA50: An archeointensity database with PHP and MySQL
Geochemistry, Geophysics, Geosystems, 2008 The GEOMAGIA50 database stores 3798 archeomagnetic and paleomagnetic intensity determinations dated to the past 50,000 years. It also stores details of the measurement setup for each determination, which are used for ranking the data according to prescribed reliability criteria. The ranking system aims to alleviate the data reliability problem inherent

Earth and Planetary Science Letters, 2011 Abstract We report new archeointensity data obtained from the analyses of baked clay elements (architectural and kiln brick fragments) sampled in Southeast Brazil and historically and/or archeologically dated between the end of the XVIth century and the beginning of the XXth century AD.

New archeointensity data from Novgorod (North-Western Russia) between c. 1100 and 1700 AD. Implications for the European intensity secular variation [PDF]
Physics of the Earth and Planetary Interiors, 2017 Abstract Reconstructing the secular variation of Europe’s geomagnetic field over the past millennium is challenging because of the lack of recently acquired archeomagnetic data from Western Russia. In this paper, we report on nine new archeointensity values obtained from groups of brick fragments sampled in Novgorod (North-Western Russia) and its ...

Earth and Planetary Science Letters, 2013 We present archeointensity data carried out on pieces of incense burners from the ancient Maya city of Palenque, Chiapas, Mexico, covering much of the Mesoamerican Classic period, from A.D. 400 to A.D. 850. We worked on pieces from 24 incense burners encompassing the five Classic ceramic phases of Palenque: Motiepa (A.D. 400–500), Cascadas (A.D.
