LONG CITATION
Prof. Evans has made major fundamental contributions to geomagnetic science. He and his colleagues used electron microscopy to demonstrate that single-domain iron oxide grains carry stable remanent magnetizations in igneous rocks, thereby verifying the physical basis of paleomagnetism. Dr. Evans showed that the geomagnetic field remained dipolar over Phanerozoic time, validating all paleomagnetic continental reconstructions. Using magnetic properties of loess deposits in China, Evans and coworkers have dated climatic changes over the last 3.5 million years. These changes strongly support Milankovitch's theory linking climatic cycles to orbital parameters. Prof. Evans’ recent book Environmental Magnetism (co-authored with Heller) will dominate this field for years to come.

SHORT CITATION
Ted Evans has made major fundamental contributions to geomagnetic science by demonstrating how iron oxide grains can carry magnetization in rocks. His work has been instrumental in validating continental reconstructions throughout important periods of earth history and in developing the field of environmental magnetism for the earth sciences. His recent book on these topics will be a key reference for many years to come.
