A group of scientists – led by Dr John Tarduno from the University of Rochester, NY – has recovered a magnetic field record from minerals for Iron Age southern Africa. The data suggest that the region of the planet’s core beneath southern Africa, referred to as the African large low shear velocity province (LLSVP), may be the birthplace of some of the more recent and future Earth’s magnetic pole reversals. Schematic illustration of...
