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 ...
Magnetic fields make life possible on Earth by protecting the planet from the Sun's harmful cosmic rays. A new study found the oldest evidence yet of this field’s existence in iron-rich rocks in ...
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 ...
Iron particles effectively act as tiny magnets that can record both magnetic field strength and direction when the process of crystallization locks them in place. The researchers found that rocks ...
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 ...
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 ...
