Most criteria used to substantiate the concept of continental drift rely on qualitative subjective interpretation and do not yield a statistically adequate proof that drift occurred across the North Atlantic Ocean. Specific variables could be used objectively to test the continental-drift model. Preferred variables are those that could establish (1) gradients parallel with a mobile belt (e.g., vectors defined by dissimilar rates of migration of fossil genera), (2) the intracratonic nature of the Caledonian and Appalachian mobile belts, and (3) the geometric separation of intersecting mobile belts.

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.
