Paleomagnetic data for nearly all geologic periods are now available from North America and Europe. The more reliable Paleozoic and Mesozoic evi-dence is analyzed in terms of some North Atlantic paleogeographic models, but the usefulness of paleomagnetism in testing such reconstructions is not obvious and depends critically upon the geometry of continental drift.
The divergence of the North American and European apparent polar-wandering curves is systematic only over their Carboniferous, Permian, and Triassic parts. The data are simultaneously compatible with two major rota-tions since the Permian: (1) separation of the two continents initially about the polar pivot proposed by...

North Atlantic—Geology and Continental Drift
The Gander Conference, an International Conference on Stratigraphy and Structure Bearing on the Origin of the North Atlantic Ocean, was held in Gander, Newfoundland, August 1967. The conference gave geologists familiar with the areas bordering the North Atlantic Ocean with an opportunity to present their knowledge and ideas to colleagues dealing with similar rocks and structures. This publication contains most of the papers that were presented at that conference and a few others that were prepared for the sessions.
