Third, magnetism in rocks can be used to estimate the age of a fossil site. This method uses the orientation of the Earth's magnetic field, which has changed through time, to determine ages for ...

Dr. Leonid Surovitskii obtained his MSc Physics degree from the St. Petersburg State University, Russia in 2007 with a specialization in Paleomagnetism and Rock Magnetism. Upon graduation, he worked ...

Previously, estimates and hints of the early Earth's magnetic field have come from individual mineral crystals called zircons found within ancient rocks from Western Australia. These had suggested ...

Chinese scientists discovered that the moon's magnetic field lasted much longer than expected, persisting into its midlife. By studying tiny rocks brought back by the Chang’e-5 mission, they found the ...
