The authors have tested the polar wander paths recently proposed for Mars by Schultz and Lutz-Garihan and for the Moon by Runcorn through a comparison of the lithospheric stress field predicted for rapid global reorientations against observed tectonic features. They have employed the theory of Vening Meinesz and of Melosh to calculate the reorientation stresses, and they argue that the formation of normal faults or graben in broad regions surrounding the former rotation poles should be the minimum tectonic signature of a reorientation that generates lithospheric stresses in excess of the extensional strength of near-surface material. It is concluded that polar wander of the magnitude and timing proposed for Mars by Schultz and Lutz-Garihan did not occur and that the tectonic test of polar wander on the Moon is inconclusive.
