Experimental studies on remanence acquisition processes and regional geomagnetic field variability from archeointensity studies [PDF]

, 2012
The dissertation comprises two separate topics. Chapters 2 and 3 are experimental studies on remanence acquisition processes. Chapters 4 and 5 investigate the geomagnetic field variability in Africa and India between 1000 BCE and 1000 CE.

Regional archeointensity curve ArchJSK2k from 600 BCE to 1700 CE for East Asia and possible recurrence of the West Pacific Anomaly

There have been reports suggesting the possibility of the West Pacific Anomaly, an area of weak magnetic fields, existing around Southeast Asia during the 15–19 th century. To verify whether such an anomaly existed in other ages, we conducted a study on archeointensity and rock magnetism using several Japanese potteries, which were made in three stages

Possible impact of the Earth's magnetic field on the history of ancient civilizations

, 2006
International audienceWe report new archeointensity results from Iranian and Syrian archeological excavations dated from the second millennium BC. These high-temperature magnetization data were obtained using a laboratory-built triaxial vibrating sample ...

Fast Geomagnetic Field Intensity Decrease Between 500 BC and 250 AD. New Archeointensity Data From South Uzbekistan.

, 2020
Recent archeomagnetic studies provide new evidences for rapid variations of the intensity of the geomagnetic field in the last millennia. In particular, during the first millennium BC, one of the biggest jerks of the geomagnetic field took place. This phenomenon has been observed in the Near East, Israel and Georgia, Germany and Western Europe.
