"Babylonian Bricks Reveal Clues to Earth's Magnetic Mysteries"

Originally Published 2 years ago — by Forbes

Researchers have used archaeomagnetism to study changes in Earth's magnetic field over the past 3,000 years by analyzing magnetic signatures in ancient clay bricks from Mesopotamia. These bricks, inscribed with the names of kings, have helped to confirm the "Levantine Iron Age geomagnetic Anomaly" and provide a new method for dating artifacts that lack organic material. The study enhances our understanding of Earth's magnetic field fluctuations and offers a new tool for archaeological dating, with implications for recognizing potential shifts in the magnetic field. The research was published in the Proceedings of the National Academy of Sciences (2023).

Unveiling Ancient Mesopotamian Bricks' Magnetic Anomaly

Originally Published 2 years ago — by Ancient Origins

Analysis of ancient Mesopotamian bricks from modern-day Iraq has revealed a dramatic spike in the Earth's magnetic field around 3,000 years ago. The bricks, containing iron oxide, were heated and cooled to erase the ancient magnetic signature and establish a ratio between the object's magnetic charge in the past and under controlled laboratory conditions. This alternative method of artifact dating, known as archaeomagnetic techniques, provides a more precise chronological record compared to traditional methods like carbon dating. The findings shed light on the Levantine Iron Age geomagnetic anomaly and offer insights into ancient Mesopotamia.
