Abstract

Combined analysis of drill-hole, gravity and magnetic data indicates that the Precambrian rocks in the basement of the Dakotas may be divided into a series of lithotectonic terrains. On the basis of an analysis of geological and geophysical data in the Dakotas and from the surrounding states and Canada, it is shown how the exposed Precambrian rocks of the adjacent shield areas project into the study area. Brief comments are made on the tectonic implications of this study. Geological and geophysical characteristics of 11 terrains are tabulated. -P.Br.
