Stress Effects on Thermoremanent Magnetization

Abstract

Hall and Neale¹ have reported accurate measurements of the directions of thermoremanent magnetization acquired by rock specimens which cooled under stress in a low magnetic field. They observed small, but consistent, differences between the directions of thermoremanent magnetization in rocks cooled under stress and without stress, and suggested that their observations conflicted with our results^2,3, which indicated the absence of measurable differences in isotropic rocks. However, we consider that the experiments of Hall and Neale are consistent both with our results and with our conclusions, which may be summarized as follows.
