However, paleointensity data are fraught with difficulties that make understanding the evolution of our planet more challenging. We demonstrate a long-sought-after quantitative relationship between fundamental rock magnetic properties and the fidelity of paleointensity records. This relationship can be used to reject low-fidelity paleointensity records and help resolve controversy that surrounds key questions about the evolution of our planet, such as when did the geodynamo begin, when did the inner core solidify, or how early life may have interacted with the magnetic field.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382544420380230656","@type":"Researcher","foaf:name":[{"@value":"Greig A.
