The tectonics of North America — A discussion to accompany the tectonic map of North America, Scale 1:5,000,000

Abstract

The "Tectonic Map of North America," on a scale of 1: 5,000,000, has been compiled by the United States Geological Survey in collaboration with other national geological surveys, and with the assistance of various individuals. The compilers made use of tectonic maps of some of the countries maps that have been published or are in process of publication. In addition, many other basic maps and reports were consulted.
