The Earth's magnetic field varies its orientation and intensity through time. Geologists compile these magnetic fluctuations into a timeline useful for dating sedimentary strata and determining the kinetic motions of tectonic plates. Until recently, this timescale has covered only the last 300 million years, or 1/15th of the Earth's total history. A new magnetic mineral recorder has been recognized that will allow the geomagnetic timescale to be expanded into the earliest portions of Earth's history. A case study from the 2 billion year-old Bushveld Complex of South Africa will be presented.
