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

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).

Mysterious Magnetic Anomaly Unveiled by Mesopotamian Bricks

Ancient Mesopotamian bricks, dating back to the third and first millennia B.C., have helped confirm a mysterious anomaly in Earth's magnetic field that occurred 3,000 years ago. Iron oxide grains within the clay of these bricks recorded changes in Earth's magnetic field when they were heated, allowing scientists to reconstruct changes in the magnetic field over time. This finding not only sheds light on the ancient anomaly but also provides a new method for dating artifacts that do not contain organic material.
