Rock Magnetism: Fundamentals and Frontiers



Since the first lodestone was used as a compass, the subject of rock magnetism has fascinated a broad range of scientists. In the late 1840s and early 1850s, A. Delesse and M. Melloni showed that Earth materials were capable of faithfully recording the ambient geomagnetic field, and in the early 1900s, P. David and B. Brunhes first recognized magnetizations anti-parallel to the local field.
