The synthesis of Cordilleran geology presented in this volume provides the reader with a summary of the current geoscience database and leading hypotheses derived therefrom. Some of the problems and questions that remain unanswered in this description of the evolution of the Canadian Cordillera are reviewed in this chapter and generally are the result of a lack of data. Many of the problems summarized below may be solved simply through detailed investigations in specific regions. Others demand greatly increased input from geophysical and geochemical studies. Finally there is a continuing need for integration of the complete spectrum of geoscience research to produce theoretical models of Cordilleran tectonic history for the benefit of resource exploration and evaluation and to provide guidance for future research.

Geology of the Cordilleran Orogen in Canada
Seven stratigraphic chapters cover time slices from Precambrian to Neogene; also included are chapters covering tectonic framework, paleomagnetism, physiographic evolution, Quaternary glaciation, volcanic and plutonic regimes, metamorphism, structural styles, metallogeny, energy and ground resources, and natural hazards. A tectonic synthesis chapter and a summary of outstanding problems round out the volume. Accompanying plates include physiographic, tectonic assemblage, terrane and metamorphic maps, correlation charts, structural cross sections, and special maps showing distribution of Proterozoic and Miocene plutonic suites and the metallogeny of terranes.
