Brad Singer Browse All Authors Top 3 quotes by Brad Singer Reversals are generated in the deepest parts of the Earth's interior, but the effects manifest themselves all the way through the Earth and especially at the Earth's surface and in the atmosphere, unless you have a complete, accurate and high-resolution record of what a field reversal really is like at the surface of the Earth, it's difficult to even discuss what the mechanics of generating a reversal are. Brad Singer top-news Lava flows are ideal recorders of the magnetic field. They have a lot of iron-bearing minerals, and when they cool, they lock in the direction of the field, but it's a spotty record. No volcanoes are erupting continuously. So we're relying on careful field work to identify the right records. Brad Singer top-news I've been working on this problem for 25 years, and now we have a richer record and better-dated record of this last reversal than ever before. Brad Singer top-news
