Detecting Remagnetization with Quantum Diamond Microscopy: A New Window into Earth’s Magnetic History
Unveiling a Hidden Chapter: Why Remagnetization Matters Rocks record Earth’s magnetic field as they form, lock in magnetic minerals, and preserve a chronology of paleomagnetic history. But the magnetic record is not always a simple, single snapshot. Over geological time, rocks can undergo remagnetization, a process that alters or adds magnetization after the original formation.…

Detecting Remagnetization with Quantum Diamond Microscopy: A New Window into Paleomagnetism
Understanding Remagnetization in Geologic Records Rock formations preserve a record of the Earth’s magnetic field through remanent magnetization. Over geological timescales, minerals can reset or acquire new magnetic signals during chemical changes, metamorphism, or recrystallization. Detecting remagnetization is essential for accurate paleomagnetic reconstructions, dating events, and understanding plate tectonics. Traditional techniques map bulk magnetization but…
