Save Big on Coursera Plus. 7,000+ courses at $160 off. Limited Time Only! Grab it Explore groundbreaking research on tectonic motion and geodynamo reversals through magnetic imaging in this 33-minute conference talk by Roger Fu. Delve into studies on the Martian meteorite ALH 84001 and 3.18-3.25 Ga terrestrial rocks from the Pilbara Craton, revealing insights into Mars' magnetic field history and Earth's early plate tectonics. Learn how micrometer-scale magnetic field imaging, particularly using the quantum diamond microscope (QDM), has enabled new discoveries about the onset of mobile-lid plate tectonics and the characteristics of Earth's early geodynamo. Gain understanding of the implications these findings have for planetary habitability, atmospheric composition, and the validity of Archean paleomagnetism.
