Paleomagnetic Reference Frame

Paleomagnetism, after morphology and geology, provided key evidence for the great precursor of plate tectonics — continental drift. One of the great hopes with plate tectonics was for paleomagnetism to provide additional kinematic constraints. Alas, the v

Preface

There's something about introductory textbooks that can be fundamentally misleading. As I plowed through freshman Physical Geology some 36 years ago, I couldn't help but acquire the impression that all of the major problems in the earth sciences had been solved. Yes, there was a chapter about Wegener's continental drift hypothesis along with a few other ideas concerning earth evolution - expansion, contraction - and including Holmes' convection cell idea. Once I began to take the field trips and participate in junior-year field camp, I began to suspect that the textbooks had left something out. It didn't take long, however, to begin hearing about the "New Global Tectonics", at which point I felt that I had been misled by what I had encountered in my first formal contact with geology. All of a sudden it was clear that there was much more to geology and geophysics than a widely used book could convey. Plate Tectonics is now into its fifth decade. I haven't looked at current introductory textbooks, so I don't know whether they still convey the impression that all of the major problems in the earth
