摘要

Ninety years ago, Bernard Brunhes reported the discovery of rocks from a roadcut in the Massif Central of France that were magnetized in exactly the opposite direction to the local geomagnetic field. Brunhes was attracted to these particular rocks-baked clays over which molten lava had flowed-because he knew from the work of Guiseppe Folgerhaiter that ancient pottery carried a particularly strong and stable magnetization. Brunhes reasoned that because the clay had been fired by the lava, like pottery, it should retain an excellent record of the magnetic field. At one site, he chiseled two samples out of the flow. He found that they also had reversed magnetic polarity.
